FX2LP contains two standard 8051 USARTs, addressed via

Special Function Register (SFR) bits. The USART interface pins

are available on separate IO pins, and are not multiplexed with

port pins.

UART0 and UART1 can operate using an internal clock at

230 KBaud with no more than 1% baud rate error. 230 KBaud

operation is achieved by an internally derived clock source that

generates overflow pulses at the appropriate time. The internal

clock adjusts for the 8051 clock rate (48 MHz, 24 MHz, and 12

MHz) such that it always presents the correct frequency for 230

3. Functional Overview

3.1 USB Signaling Speed

FX2LP operates at two of the three rates defined in the USB

Specification Revision 2.0, dated April 27, 2000:

KBaud operation.

■ Full-speed, with a signaling bit rate of 12 Mbps

3.2.3 Special Function Registers

■ High-speed, with a signaling bit rate of 480 Mbps.

Certain 8051 SFR addresses are populated to provide fast

access to critical FX2LP functions. These SFR additions are

shown in T a ble 1 on page 4. Bold type indicates non standard,

enhanced 8051 registers. The two SFR rows that end with “0”

and “8” contain bit addressable registers. The four IO ports A to

D use the SFR addresses used in the standard 8051 for ports 0

to 3, which are not implemented in FX2LP. Because of the faster

and more efficient SFR addressing, the FX2LP IO ports are not

addressable in external RAM space (using the MOVX

instruction).

FX2LP does not support the low speed signaling mode of

1.5 Mbps.

3.2 8051 Microprocessor

The 8051 microprocessor embedded in the FX2LP family has

256 bytes of register RAM, an expanded interrupt system, three

timer/counters, and two USARTs.

3.2.1 8051 Clock Frequency

FX2LP has an on-chip oscillator circuit that uses an external 24

MHz (±100 ppm) crystal with the following characteristics:

3.3 I C Bus

FX2LP supports the I C bus as a master only at 100-/400- KHz.

SCL and SDA pins have open-drain outputs and hysteresis

inputs. These signals must be pulled up to 3.3V, even if no I C

device is connected.

Two control bits in the USBCS (USB Control and Status) register,

control the ReNumeration process: DISCON and RENUM. To

simulate a USB disconnect, the firmware sets DISCON to 1. To

reconnect, the firmware clears DISCON to 0.

3.5 USB Boot Methods

During the power up sequence, internal logic checks the I C port

for the connection of an EEPROM whose first byte is either 0xC0

or 0xC2. If found, it uses the VID/PID/DID values in the EEPROM

in place of the internally stored values (0xC0), or it boot-loads the

EEPROM contents into internal RAM (0xC2). If no EEPROM is

detected, FX2LP enumerates using internally stored descriptors.

The default ID values for FX2LP are VID/PID/DID (0x04B4,

Before reconnecting, the firmware sets or clears the RENUM bit

to indicate whether the firmware or the Default USB Device

handles device requests over endpoint zero: if RENUM = 0, the

Default USB Device handles device requests; if RENUM = 1, the

firmware services the requests.

3.8.1 INT2 Interrupt Request and Enable Registers

FX2LP implements an autovector feature for INT2 and INT4.

There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF)

vectors. See EZ-USB Technical Reference Manual (TRM) for

more details.

3.6 ReNumeration™

Because the FX2LP’s configuration is soft, one chip can take on

the identities of multiple distinct USB devices.

3.8.2 USB Interrupt Autovectors

When first plugged into USB, the FX2LP enumerates automati-

cally and downloads firmware and USB descriptor tables over

the USB cable. Next, the FX2LP enumerates again, this time as

a device defined by the downloaded information. This patented

two step process called ReNumeration™ happens instantly when

the device is plugged in, without a hint that the initial download

step has occurred.

The main USB interrupt is shared by 27 interrupt sources. To

save the code and processing time that is required to identify the

individual USB interrupt source, the FX2LP provides a second

level of interrupt vectoring, called Autovectoring. When a USB

interrupt is asserted, the FX2LP pushes the program counter

onto its stack then jumps to the address 0x0043 where it expects

to find a “jump” instruction to the USB Interrupt service routine.

Note

2. The I C bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this detection method does not work properly.

3.8.3 FIFO/GPIF Interrupt (INT4)

Just as the USB Interrupt is shared among 27 individual USB

interrupt sources, the FIFO/GPIF interrupt is shared among 14

individual FIFO/GPIF sources. The FIFO/GPIF Interrupt, like the

USB Interrupt, can employ autovectoring. T a ble 4 shows the

priority and INT4VEC values for the 14 FIFO/GPIF interrupt

of the crystal and the PLL. This reset period must be approxi-

mately 5 ms after VCC reaches 3.0V. If the crystal input pin is

driven by a clock signal the internal PLL stabilizes in 200 μs after

[3]

VCC has reached 3.0V.

Figure 2 on page 7 shows a power on reset condition and a reset

applied during operation. A power on reset is defined as the time

reset that is asserted while power is being applied to the circuit.

A powered reset is when the FX2LP powered on and operating

Two memory maps are shown in the following diagrams:

Figure 4 on page 9 shows the External Code Memory, EA = 1.

3.9.2 Wakeup Pins

The 8051 puts itself and the rest of the chip into a power down

mode by setting PCON.0 = 1. This stops the oscillator and PLL.

When WAKEUP is asserted by external logic the oscillator

restarts after the PLL stabilizes, and the 8051 receives a wakeup

interrupt. This applies whether or not FX2LP is connected to the

USB.

3.10.2 Internal Code Memory, EA = 0

This mode implements the internal 16 KByte block of RAM

(starting at 0) as combined code and data memory. When

external RAM or ROM is added, the external read and write

strobes are suppressed for memory spaces that exist inside the

chip. This enables the user to connect a 64 KByte memory

without requiring address decodes to keep clear of internal

memory spaces.

The FX2LP exits the power down (USB suspend) state using one

of the following methods:

■ USB bus activity (if D+/D– lines are left floating, noise on these

lines may indicate activity to the FX2LP and initiate a wakeup)

Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM

spaces have the following access:

■ External logic asserts the WAKEUP pin

■ USB download

■ USB upload

■ External logic asserts the PA3/WU2 pin

The second wakeup pin, WU2, can also be configured as a

general purpose IO pin. This enables a simple external R-C

network to be used as a periodic wakeup source. WAKEUP is by

default active LOW.

■ Setup data pointer

■ I C interface boot load.

3.10.3 External Code Memory, EA = 1

The bottom 16 KBytes of program memory is external and

therefore the bottom 16 KBytes of internal RAM is accessible

only as a data memory.

configured to a 512 byte buffer, in full-speed only the first 64

bytes are used. The unused endpoint buffer space is not

8051-IO domain. The blocks can be configured as single,

double, triple, or quad buffered as previously shown.

3.13 External FIFO Interface

3.13.1 Architecture

The IO control unit implements either an internal master (M for

master) or external master (S for Slave) interface.

The FX2LP slave FIFO architecture has eight 512 byte blocks in

the endpoint RAM that directly serve as FIFO memories and are

controlled by FIFO control signals (such as IFCLK, SLCS#,

SLRD, SLWR, SLOE, PKTEND, and flags).

In Master (M) mode, the GPIF internally controls FIFOADR[1..0]

to select a FIFO. The RDY pins (two in the 56-pin package, six

in the 100-pin and 128-pin packages) can be used as flag inputs

from an external FIFO or other logic if desired. The GPIF can be

run from either an internally derived clock or externally supplied

clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s

(48-MHz IFCLK with 16-bit interface).

In operation, some of the eight RAM blocks fill or empty from the

SIE, while the others are connected to the IO transfer logic. The

transfer logic takes two forms, the GPIF for internally generated

control signals and the slave FIFO interface for externally

controlled transfers.

In Slave (S) mode, the FX2LP accepts either an internally

derived clock or externally supplied clock (IFCLK, max frequency

48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals

from external logic. When using an external IFCLK, the external

clock must be present before switching to the external clock with

the IFCLKSRC bit. Each endpoint can individually be selected

for byte or word operation by an internal configuration bit and a

Slave FIFO Output Enable signal SLOE enables data of the

selected width. External logic must ensure that the output enable

signal is inactive when writing data to a slave FIFO. The slave

interface can also operate asynchronously, where the SLRD and

SLWR signals act directly as strobes, rather than a clock qualifier

as in synchronous mode. The signals SLRD, SLWR, SLOE and

PKTEND are gated by the signal SLCS#.

3.13.2 Master/Slave Control Signals

The FX2LP endpoint FIFOS are implemented as eight physically

distinct 256x16 RAM blocks. The 8051/SIE can switch any of the

RAM blocks between two domains, the USB (SIE) domain and

the 8051-IO Unit domain. This switching is done virtually instan-

taneously, giving essentially zero transfer time between “USB

FIFOS” and “Slave FIFOS.” Because they are physically the

same memory no bytes are actually transferred between buffers.

At any given time, some RAM blocks are filling/emptying with

USB data under SIE control, while other RAM blocks are

available to the 8051, the IO control unit or both. The RAM blocks

operate as single port in the USB domain, and dual port in the

Notes

4. “0” means “not implemented.”

5. “2×” means “double buffered.”

6. Even though these buffers are 64 bytes, they are reported as 512 for USB 2.0 compliance. The user must never transfer packets larger than 64 bytes to EP1.

3.15 ECC Generation^[7]

3.13.3 GPIF and FIFO Clock Rates

An 8051 register bit selects one of two frequencies for the inter-

nally supplied interface clock: 30 MHz and 48 MHz. Alternatively,

an externally supplied clock of 5 MHz–48 MHz feeding the IFCLK

pin can be used as the interface clock. IFCLK can be configured

to function as an output clock when the GPIF and FIFOs are

internally clocked. An output enable bit in the IFCONFIG register

turns this clock output off, if desired. Another bit within the

IFCONFIG register inverts the IFCLK signal whether internally or

externally sourced.

The EZ-USB can calculate ECCs (Error Correcting Codes) on

data that passes across its GPIF or Slave FIFO interfaces. There

are two ECC configurations: Two ECCs, each calculated over

256 bytes (SmartMedia Standard); and one ECC calculated over

512 bytes.

The ECC can correct any one-bit error or detect any two-bit error.

3.15.1 ECC Implementation

The two ECC configurations are selected by the ECCM bit:

ECCM = 0

3.14 GPIF

The GPIF is a flexible 8-bit or 16-bit parallel interface driven by

a user programmable finite state machine. It enables the

CY7C68013A/15A to perform local bus mastering and can

implement a wide variety of protocols such as ATA interface,

printer parallel port, and Utopia.

Two 3 byte ECCs, each calculated over a 256 byte block of data.

This configuration conforms to the SmartMedia Standard.

Write any value to ECCRESET, then pass data across the GPIF

or Slave FIFO interface. The ECC for the first 256 bytes of data

is calculated and stored in ECC1. The ECC for the next 256 bytes

is stored in ECC2. After the second ECC is calculated, the values

in the ECCx registers do not change until ECCRESET is written

again, even if more data is subsequently passed across the

interface.

The GPIF has six programmable control outputs (CTL), nine

address outputs (GPIFADRx), and six general-purpose ready

inputs (RDY). The data bus width can be 8 or 16 bits. Each GPIF

vector defines the state of the control outputs, and determines

what state a ready input (or multiple inputs) must be before

proceeding. The GPIF vector can be programmed to advance a

FIFO to the next data value, advance an address, etc. A

sequence of the GPIF vectors make up a single waveform that

is executed to perform the desired data move between the

FX2LP and the external device.

ECCM = 1

One 3 byte ECC calculated over a 512 byte block of data.

Write any value to ECCRESET then pass data across the GPIF

or Slave FIFO interface. The ECC for the first 512 bytes of data

is calculated and stored in ECC1; ECC2 is unused. After the

ECC is calculated, the values in ECC1 do not change even if

more data is subsequently passed across the interface, till

ECCRESET is written again.

3.14.1 Six Control OUT Signals

The 100-pin and 128-pin packages bring out all six Control

Output pins (CTL0-CTL5). The 8051 programs the GPIF unit to

define the CTL waveforms. The 56-pin package brings out three

of these signals, CTL0–CTL2. CTLx waveform edges can be

programmed to make transitions as fast as once per clock (20.8

ns using a 48-MHz clock).

3.16 USB Uploads and Downloads

The core has the ability to directly edit the data contents of the

internal 16 KByte RAM and of the internal 512 byte scratch pad

RAM via a vendor specific command. This capability is normally

used when soft downloading user code and is available only to

and from internal RAM, only when the 8051 is held in reset. The

available RAM spaces are 16 KBytes from 0x0000–0x3FFF

(code/data) and 512 bytes from 0xE000–0xE1FF (scratch pad

3.14.2 Six Ready IN Signals

The 100-pin and 128-pin packages bring out all six Ready inputs

(RDY0–RDY5). The 8051 programs the GPIF unit to test the

RDY pins for GPIF branching. The 56-pin package brings out two

of these signals, RDY0–1.

data RAM).

3.17 Autopointer Access

3.14.3 Nine GPIF Address OUT Signals

FX2LP provides two identical autopointers. They are similar to

the internal 8051 data pointers but with an additional feature:

they can optionally increment after every memory access. This

capability is available to and from both internal and external

RAM. The autopointers are available in external FX2LP registers

under control of a mode bit (AUTOPTRSET-UP.0). Using the

external FX2LP autopointer access (at 0xE67B – 0xE67C)

enables the autopointer to access all internal and external RAM

to the part.

Nine GPIF address lines are available in the 100-pin and 128-pin

packages, GPIFADR[8..0]. The GPIF address lines enable

indexing through up to a 512 byte block of RAM. If more address

lines are needed IO port pins are used.

3.14.4 Long Transfer Mode

In the master mode, the 8051 appropriately sets GPIF trans-

action count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or

GPIFTCB0) for unattended transfers of up to 2 transactions.

Also, the autopointers can point to any FX2LP register or

endpoint buffer space. When autopointer access to external

memory is enabled, location 0xE67B and 0xE67C in XDATA and

code space cannot be used.

The GPIF automatically throttles data flow to prevent under or

overflow until the full number of requested transactions

complete. The GPIF decrements the value in these registers to

represent the current status of the transaction.

Notes

7. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.

8. After the data has been downloaded from the host, a “loader” can execute from internal RAM to transfer downloaded data to external memory.

The EZ-USB FX2LP is form, fit and with minor exceptions

functionally compatible with its predecessor, the EZ-USB FX2.

This makes for an easy transition for designers wanting to

upgrade their systems from the FX2 to the FX2LP. The pinout

and package selection are identical and a vast majority of

firmware previously developed for the FX2 functions in the

FX2LP.

For designers migrating from the FX2 to the FX2LP a change in

Differences

4. Pin Assignments

Figure 6 on page 15 identifies all signals for the five package

types. The following pages illustrate the individual pin diagrams,

plus a combination diagram showing which of the full set of

signals are available in the 128-pin, 100-pin, and 56-pin

packages.

CY7C68013A is identical to CY7C68014A in form, fit, and

functionality. CY7C68015A is identical to CY7C68016A in form,

fit, and functionality. CY7C68014A and CY7C68016A have a

lower suspend current than CY7C68013A and CY7C68015A

respectively and are ideal for power sensitive battery applica-

tions.

The signals on the left edge of the 56-pin package in Figure 6

on page 15 are common to all versions in the FX2LP family with

the noted differences between the CY7C68013A/14A and the

CY7C68015A/16A.

CY7C68015A and CY7C68016A are available in 56-pin QFN

package only. Two additional GPIO signals are available on the

CY7C68015A and CY7C68016A to provide more flexibility when

neither IFCLK or CLKOUT are needed in the 56-pin package.

Three modes are available in all package versions: Port, GPIF

master, and Slave FIFO. These modes define the signals on the

right edge of the diagram. The 8051 selects the interface mode

using the IFCONFIG[1:0] register bits. Port mode is the power on

default configuration.

USB developers wanting to convert their FX2 56-pin application

to a bus-powered system directly benefit from these additional

signals. The two GPIOs give developers the signals they need

for the power control circuitry of their bus-powered application

without pushing them to a high pincount version of FX2LP.

The 100-pin package adds functionality to the 56-pin package by

adding these pins:

The CY7C68015A is only available in the 56-pin QFN package

The 128-pin package adds the 8051 address and data buses

plus control signals. Note that two of the required signals, RD#

and WR#, are present in the 100-pin version.

In the 100-pin and 128-pin versions, an 8051 control bit can be

set to pulse the RD# and WR# pins when the 8051 reads

from/writes to PORTC. This feature is enabled by setting

PORTCSTB bit in CPUCS register.

Section 10.5 displays the timing diagram of the read and write

strobing function on accessing PORTC.

10.5 PORTC Strobe Feature Timings

The RD# and WR# are present in the 100-pin version and the

128-pin package. In these 100-pin and 128-pin versions, an

8051 control bit can be set to pulse the RD# and WR# pins when

the 8051 reads from or writes to PORTC. This feature is enabled

by setting PORTCSTB bit in CPUCS register.

The RD# signal prompts the external logic to prepare the next

data byte. Nothing gets sampled internally on assertion of the

RD# signal itself, it is just a prefetch type signal to get the next

data byte prepared. So, using it with that in mind easily meets the

setup time to the next read.

The RD# and WR# strobes are asserted for two CLKOUT cycles

when PORTC is accessed.

The purpose of this pulsing of RD# is to allow the external

peripheral to know that the 8051 is done reading PORTC and the

data was latched into PORTC three CLKOUT cycles before

asserting the RD# signal. After the RD# is pulsed, the external

logic can update the data on PORTC.

The WR# strobe is asserted two clock cycles after PORTC is

updated and is active for two clock cycles after that, as shown in

Figure 15.

Following is the timing diagram of the read and write strobing

function on accessing PORTC. Refer to Section 10.3 and

Section 10.4 for details on propagation delay of RD# and WR#

signals.

As for read, the value of PORTC three clock cycles before the

assertion of RD# is the value that the 8051 reads in. The RD# is

pulsed for 2 clock cycles after 3 clock cycles from the point when

the 8051 has performed a read function on PORTC.

There is no specific timing requirement that should be met for

asserting PKTEND pin to asserting SLWR. PKTEND can be

asserted with the last data value clocked into the FIFOs or there-

caused the last byte or word to be clocked into the previous auto

committed packet. Figure 23 shows this scenario. X is the value

the AUTOINLEN register is set to when the IN endpoint is

configured to be in auto mode.

after. The setup time t

and the hold time t

must be met.

SPE

PEH

Although there are no specific timing requirements for the

PKTEND assertion, there is a specific corner case condition that

needs attention while using the PKTEND to commit a one byte

or word packet. There is an additional timing requirement that

needs to be met when the FIFO is configured to operate in auto

mode and it is required to send two packets back to back: a full

packet (full defined as the number of bytes in the FIFO meeting

the level set in AUTOINLEN register) committed automatically

followed by a short one byte or word packet committed manually

using the PKTEND pin. In this scenario, the user must ensure to

assert PKTEND at least one clock cycle after the rising edge that

Figure 23 shows a scenario where two packets are committed.

The first packet gets committed automatically when the number

of bytes in the FIFO reaches X (value set in AUTOINLEN

committed manually using PKTEND.

Note that there is at least one IFCLK cycle timing between the

assertion of PKTEND and clocking of the last byte of the previous

packet (causing the packet to be committed automatically).

Failing to adhere to this timing results in the FX2 failing to send

the one byte or word short packet.

Figure 29 shows the timing relationship of the SLAVE FIFO

signals during a synchronous FIFO read using IFCLK as the

synchronizing clock. The diagram illustrates a single read

followed by a burst read.

If the SLCS signal is used, it must be asserted before SLRD is

asserted (The SLCS and SLRD signals must both be asserted

to start a valid read condition).

■ The FIFO pointer is updated on the rising edge of the IFCLK,

while SLRD is asserted. This starts the propagation of data

IFCLK) the new data value is present. N is the first data value

read from the FIFO. To have data on the FIFO data bus, SLOE

MUST also be asserted.

■ At t = 1, SLOE is asserted. SLOE is an output enable only,

whose sole function is to drive the data bus. The data that is

driven on the bus is the data that the internal FIFO pointer is

currently pointing to. In this example it is the first data value in

the FIFO. Note: the data is pre-fetched and is driven on the bus

when SLOE is asserted.

The same sequence of events are shown for a burst read and

are marked with the time indicators of T = 0 through 5.

Note For the burst mode, the SLRD and SLOE are left asserted

during the entire duration of the read. In the burst read mode,

when SLOE is asserted, data indexed by the FIFO pointer is on

the data bus. During the first read cycle, on the rising edge of the

clock the FIFO pointer is updated and increments to point to

address N+1. For each subsequent rising edge of IFCLK, while

the SLRD is asserted, the FIFO pointer is incremented and the

next data value is placed on the data bus.

The Figure 31 shows the timing relationship of the SLAVE FIFO

signals during a synchronous write using IFCLK as the synchro-

nizing clock. The diagram illustrates a single write followed by

burst write of 3 bytes and committing all 4 bytes as a short packet

using the PKTEND pin.

FIFO data bus is written to the FIFO on every rising edge of

IFCLK. The FIFO pointer is updated on each rising edge of

IFCLK. In Figure 31, after the four bytes are written to the FIFO,

SLWR is deasserted. The short 4 byte packet can be committed

to the host by asserting the PKTEND signal.

There is no specific timing requirement that should be met for

asserting PKTEND signal with regards to asserting the SLWR

signal. PKTEND can be asserted with the last data value or

number of data values committed includes the last value written

to the FIFO. In this example, both the data value and the

PKTEND signal are clocked on the same rising edge of IFCLK.

PKTEND can also be asserted in subsequent clock cycles. The

FIFOADDR lines should be held constant during the PKTEND

assertion.

Although there are no specific timing requirement for the

PKTEND assertion, there is a specific corner case condition that

needs attention while using the PKTEND to commit a one

byte/word packet. Additional timing requirements exists when

the FIFO is configured to operate in auto mode and it is desired

to send two packets: a full packet (full defined as the number of

bytes in the FIFO meeting the level set in AUTOINLEN register)

packet committed manually using the PKTEND pin.

If the SLCS signal is used, it must be asserted with SLWR or

before SLWR is asserted (The SLCS and SLWR signals must

both be asserted to start a valid write condition).

■ While the SLWR is asserted, data is written to the FIFO and on

the rising edge of the IFCLK, the FIFO pointer is incremented.

The FIFO flag is also updated after a delay of t

from the

XFLG

rising edge of the clock.

In this case, the external master must ensure to assert the

PKTEND pin at least one clock cycle after the rising edge that

caused the last byte or word that needs to be clocked into the

previous auto committed packet (the packet with the number of

bytes equal to what is set in the AUTOINLEN register). Refer to

Figure 23 for further details on this timing.

The same sequence of events are also shown for a burst write

and are marked with the time indicators of T = 0 through 5.

Note For the burst mode, SLWR and SLCS are left asserted for

the entire duration of writing all the required data values. In this

burst write mode, after the SLWR is asserted, the data on the

Figure 32 shows the timing relationship of the SLAVE FIFO

13. PCB Layout Recommendations

Follow these recommendations to ensure reliable high perfor-

mance operation:

■ Bypass and flyback caps on VBus, near connector, are recom-

mended.

[24]

■ Four layer impedance controlled boards are required to

maintain signal quality.

■ DPLUS and DMINUS trace lengths should be kept to within 2

mm of each other in length, with preferred length of 20 to

30 mm.

■ Specify impedance targets (ask your board vendor what they

can achieve).

■ Maintain a solid ground plane under the DPLUS and DMINUS

traces. Do not allow the plane to split under these traces.

■ To control impedance, maintain trace widths and trace spacing.

■ Do not place vias on the DPLUS or DMINUS trace routing.

■ Minimize stubs to minimize reflected signals.

■ Isolate the DPLUS and DMINUS traces from all other signal

traces by no less than 10 mm.

■ Connections between the USB connector shell and signal

ground must be near the USB connector.

14. Quad Flat Package No Leads (QFN) Package Design Notes

Electrical contact of the part to the Printed Circuit Board (PCB)

is made by soldering the leads on the bottom surface of the

package to the PCB. Hence, special attention is required to the

heat transfer area below the package to provide a good thermal

bond to the circuit board. Design a Copper (Cu) fill in the PCB as

a thermal pad under the package. Heat is transferred from the

FX2LP through the device’s metal paddle on the bottom side of

the package. Heat from here is conducted to the PCB at the

thermal pad. It is then conducted from the thermal pad to the

PCB inner ground plane by a 5 x 5 array of via. A via is a plated

through hole in the PCB with a finished diameter of 13 mil. The

QFN’s metal die paddle must be soldered to the PCB’s thermal

pad. Solder mask is placed on the board top side over each via

to resist solder flow into the via. The mask on the top side also

minimizes outgassing during the solder reflow process.

For further information on this package design refer to Appli-

cation Notes for Surface Mount Assembly of Amkor's MicroLead-

Frame (MLF) Packages. You can find this on Amkor's website

http://www.amkor.com.

The application note provides detailed information about board

mounting guidelines, soldering flow, rework process, etc.

Figure 40 shows

cross-sectional area underneath the

package. The cross section is of only one via. The solder paste

template should be designed to allow at least 50% solder

coverage. The thickness of the solder paste template should be

5 mil. Use the No Clean type 3 solder paste for mounting the part.

Nitrogen purge is recommended during reflow.

Figure 41 is a plot of the solder mask pattern and Figure 42
