Functional Overview

the internal burst counter regardless of the state of chip

enables inputs or WE. WE is latched at the beginning of a burst

cycle. Therefore, the type of access (Read or Write) is

maintained throughout the burst sequence.

The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 are

synchronous-pipelined Burst NoBL SRAMs designed specifi-

cally to eliminate wait states during Write/Read transitions. All

synchronous inputs pass through input registers controlled by

the rising edge of the clock. The clock signal is qualified with

the Clock Enable input signal (CEN). If CEN is HIGH, the clock

signal is not recognized and all internal states are maintained.

All synchronous operations are qualified with CEN. All data

outputs pass through output registers controlled by the rising

edge of the clock. Maximum access delay from the clock rise

Single Write Accesses

Write access are initiated when the following conditions are

satisfied at clock rise: (1) CEN is asserted LOW, (2) CE , CE ,

and CE are ALL asserted active, and (3) the write signal WE

is asserted LOW. The address presented to the address inputs

is loaded into the Address Register. The write signals are

latched into the Control Logic block.

On the subsequent clock rise the data lines are automatically

Accesses can be initiated by asserting all three Chip Enables

(CE , CE , CE ) active at the rising edge of the clock. If Clock

Enable (CEN) is active LOW and ADV/LD is asserted LOW,

the address presented to the device will be latched. The

satisfied at clock rise: (1) CEN is asserted LOW, (2) CE , CE ,

and CE are ALL asserted active, (3) the Write Enable input

signal WE is deasserted HIGH, and (4) ADV/LD is asserted

LOW. The address presented to the address inputs is latched

into the Address Register and presented to the memory core

and control logic. The control logic determines that a read

access is in progress and allows the requested data to

propagate to the input of the output register. At the rising edge

of the next clock the requested data is allowed to propagate

through the output register and onto the data bus within 2.6 ns

(200-MHz device) provided OE is active LOW. After the first

clock of the read access the output buffers are controlled by

OE and the internal control logic. OE must be driven LOW in

order for the device to drive out the requested data. During the

second clock, a subsequent operation (Read/Write/Deselect)

can be initiated. Deselecting the device is also pipelined.

Therefore, when the SRAM is deselected at clock rise by one

of the chip enable signals, its output will three-state following

the next clock rise.

synchronous

self-timed write mechanism has been provided to simplify the

write operations. Byte write capability has been included in

order to greatly simplify Read/Modify/Write sequences, which

can be reduced to simple byte write operations.

Because the CY7C1460AV25/CY7C1462AV25/CY7C1464AV25

are common I/O devices, data should not be driven into the

device while the outputs are active. The Output Enable (OE)

Burst Read Accesses

The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 have

an on-chip burst counter that allows the user the ability to

supply a single address and conduct up to four Reads without

reasserting the address inputs. ADV/LD must be driven LOW

in order to load a new address into the SRAM, as described in

the Single Read Access section above. The sequence of the

burst counter is determined by the MODE input signal. A LOW

input on MODE selects a linear burst mode, a HIGH selects an

interleaved burst sequence. Both burst counters use A0 and

A1 in the burst sequence, and will wrap-around when incre-

mented sufficiently. A HIGH input on ADV/LD will increment

Test Data-In (TDI)

IEEE 1149.1 Serial Boundary Scan (JTAG)

The TDI ball is used to serially input information into the

registers and can be connected to the input of any of the

registers. The register between TDI and TDO is chosen by the

instruction that is loaded into the TAP instruction register. TDI

is internally pulled up and can be unconnected if the TAP is

unused in an application. TDI is connected to the most signif-

icant bit (MSB) of any register. (See Tap Controller Block

Diagram.)

The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 incor-

porates a serial boundary scan test access port (TAP). This

part is fully compliant with 1149.1. The TAP operates using

JEDEC-standard 2.5V/1.8V I/O logic level.

The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 contains

a TAP controller, instruction register, boundary scan register,

bypass register, and ID register.

Disabling the JTAG Feature

Test Data-Out (TDO)

It is possible to operate the SRAM without using the JTAG

feature. To disable the TAP controller, TCK must be tied

LOW(VSS) to prevent clocking of the device. TDI and TMS are

internally pulled up and may be unconnected. They may alter-

nately be connected to VDD through a pull-up resistor. TDO

should be left unconnected. Upon power-up, the device will

come up in a reset state which will not interfere with the

operation of the device.

The TDO output ball is used to serially clock data-out from the

registers. The output is active depending upon the current

state of the TAP state machine. The output changes on the

falling edge of TCK. TDO is connected to the least significant

bit (LSB) of any register. (See Tap Controller State Diagram.)

rising edges of TCK. This RESET does not affect the operation

of the SRAM and may be performed while the SRAM is

operating.

UPDATE-DR

UPDATE-IR

At power-up, the TAP is reset internally to ensure that TDO

comes up in a High-Z state.

The 0/1 next to each state represents the value of TMS at the

rising edge of TCK.

TAP Registers

Registers are connected between the TDI and TDO balls and

allow data to be scanned into and out of the SRAM test

circuitry. Only one register can be selected at a time through

the instruction register. Data is serially loaded into the TDI ball

on the rising edge of TCK. Data is output on the TDO ball on

the falling edge of TCK.

Test Access Port (TAP)

Test Clock (TCK)

The test clock is used only with the TAP controller. All inputs

are captured on the rising edge of TCK. All outputs are driven

from the falling edge of TCK.

Instruction Register

Test MODE SELECT (TMS)

Three-bit instructions can be serially loaded into the instruction

TDI and TDO balls as shown in the Tap Controller Block

Diagram. Upon power-up, the instruction register is loaded

with the IDCODE instruction. It is also loaded with the IDCODE

instruction if the controller is placed in a reset state as

described in the previous section.

The TMS input is used to give commands to the TAP controller

and is sampled on the rising edge of TCK. It is allowable to

leave this ball unconnected if the TAP is not used. The ball is

pulled up internally, resulting in a logic HIGH level.

When the TAP controller is in the Capture-IR state, the two

least significant bits are loaded with a binary “01” pattern to

allow for fault isolation of the board-level serial test data path.

SAMPLE Z

The SAMPLE Z instruction causes the boundary scan register

to be connected between the TDI and TDO pins when the TAP

controller is in a Shift-DR state. The SAMPLE Z command puts

the output bus into a High-Z state until the next command is

given during the “Update IR” state.

Bypass Register

To save time when serially shifting data through registers, it is

sometimes advantageous to skip certain chips. The bypass

TDI and TDO balls. This allows data to be shifted through the

SRAM with minimal delay. The bypass register is set LOW

SAMPLE/PRELOAD

SAMPLE/PRELOAD is a 1149.1-mandatory instruction. When

the SAMPLE/PRELOAD instructions are loaded into the

instruction register and the TAP controller is in the Capture-DR

state, a snapshot of data on the inputs and output pins is

captured in the boundary scan register.

(V ) when the BYPASS instruction is executed.

Boundary Scan Register

The boundary scan register is connected to all the input and

bidirectional balls on the SRAM. The length of the Boundary

Scan Register for the SRAM in different packages is listed in

the Scan Register Sizes table.

The user must be aware that the TAP controller clock can only

operate at a frequency up to 20 MHz, while the SRAM clock

operates more than an order of magnitude faster. Because

there is a large difference in the clock frequencies, it is

possible that during the Capture-DR state, an input or output

will undergo a transition. The TAP may then try to capture a

signal while in transition (metastable state). This will not harm

the device, but there is no guarantee as to the value that will

be captured. Repeatable results may not be possible.

The boundary scan register is loaded with the contents of the

RAM I/O ring when the TAP controller is in the Capture-DR

state and is then placed between the TDI and TDO balls when

the controller is moved to the Shift-DR state. The EXTEST,

SAMPLE/PRELOAD and SAMPLE Z instructions can be used

to capture the contents of the I/O ring.

To guarantee that the boundary scan register will capture the

correct value of a signal, the SRAM signal must be stabilized

long enough to meet the TAP controller's capture set-up plus

The Boundary Scan Order tables show the order in which the

bits are connected. Each bit corresponds to one of the bumps

on the SRAM package. The MSB of the register is connected

to TDI, and the LSB is connected to TDO.

hold times (t and t ). The SRAM clock input might not be

captured correctly if there is no way in a design to stop (or

slow) the clock during a SAMPLE/PRELOAD instruction. If this

is an issue, it is still possible to capture all other signals and

simply ignore the value of the CK and CK# captured in the

boundary scan register.

Identification (ID) Register

The ID register is loaded with a vendor-specific, 32-bit code

during the Capture-DR state when the IDCODE command is

loaded in the instruction register. The IDCODE is hardwired

into the SRAM and can be shifted out when the TAP controller

is in the Shift-DR state. The ID register has a vendor code and

other information described in the Identification Register

Definitions table.

Once the data is captured, it is possible to shift out the data by

putting the TAP into the Shift-DR state. This places the

boundary scan register between the TDI and TDO pins.

PRELOAD allows an initial data pattern to be placed at the

latched parallel outputs of the boundary scan register cells

prior to the selection of another boundary scan test operation.

TAP Instruction Set

The shifting of data for the SAMPLE and PRELOAD phases

can occur concurrently when required—that is, while data

captured is shifted out, the preloaded data can be shifted in.

Overview

Eight different instructions are possible with the three bit

instruction register. All combinations are listed in the

Instruction Codes table. Three of these instructions are listed

as RESERVED and should not be used. The other five instruc-

tions are described in detail below.

BYPASS

When the BYPASS instruction is loaded in the instruction

advantage of the BYPASS instruction is that it shortens the

boundary scan path when multiple devices are connected

together on a board.

Instructions are loaded into the TAP controller during the

Shift-IR state when the instruction register is placed between

TDI and TDO. During this state, instructions are shifted

through the instruction register through the TDI and TDO balls.

To execute the instruction once it is shifted in, the TAP

controller needs to be moved into the Update-IR state.

EXTEST

The EXTEST instruction enables the preloaded data to be

driven out through the system output pins. This instruction also

selects the boundary scan register to be connected for serial

access between the TDI and TDO in the shift-DR controller

state.

IDCODE

The IDCODE instruction causes a vendor-specific, 32-bit code

to be loaded into the instruction register. It also places the

instruction register between the TDI and TDO balls and allows

the IDCODE to be shifted out of the device when the TAP

controller enters the Shift-DR state.

EXTEST Output Bus Tri-State

IEEE Standard 1149.1 mandates that the TAP controller be

able to put the output bus into a tri-state mode.

The IDCODE instruction is loaded into the instruction register

upon power-up or whenever the TAP controller is given a test

logic reset state.

The boundary scan register has a special bit located at bit #89

(for 165-FBGA package) or bit #138 (for 209 FBGA package).

When this scan cell, called the “extest output bus tri-state,” is

latched into the preload register during the “Update-DR” state

output (Q-bus) pins, when the EXTEST is entered as the

current instruction. When HIGH, it will enable the output

buffers to drive the output bus. When LOW, this bit will place

the output bus into a High-Z condition.
