Features

Functional Description^[1]

• Supports 100, 133-MHz bus operations

• Supports 100-MHz bus operations (Automotive)

• 256K × 36/512K × 18 common I/O

The CY7C1361C/CY7C1363C is a 3.3V, 256K x 36/512K x 18

Synchronous Flow-through SRAMs, respectively designed to

interface with high-speed microprocessors with minimum glue

logic. Maximum access delay from clock rise is 6.5 ns

(133-MHz version). A 2-bit on-chip counter captures the first

address in a burst and increments the address automatically

for the rest of the burst access. All synchronous inputs are

gated by registers controlled by a positive-edge-triggered

Clock Input (CLK). The synchronous inputs include all

• 3.3V –5% and +10% core power supply (V

)

• 2.5V or 3.3V I/O power supply (V

• Fast clock-to-output times

— 6.5 ns (133-MHz version)

)

addresses, all data inputs, address-pipelining Chip Enable

[2]

• Provide high-performance 2-1-1-1 access rate

(CE ), depth-expansion Chip Enables (CE and CE ), Burst

Control inputs (ADSC, ADSP, and ADV), Write Enables (BW ,

• User-selectable burst counter supporting Intel

and BWE), and Global Write (GW). Asynchronous inputs

include the Output Enable (OE) and the ZZ pin.

Pentium interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed write

The CY7C1361C/CY7C1363C allows either interleaved or

linear burst sequences, selected by the MODE input pin. A

HIGH selects an interleaved burst sequence, while a LOW

selects a linear burst sequence. Burst accesses can be

initiated with the Processor Address Strobe (ADSP) or the

cache Controller Address Strobe (ADSC) inputs. Address

advancement is controlled by the Address Advancement

(ADV) input.

• Asynchronous output enable

• Available in lead-free 100-Pin TQFP package, lead-free

and non lead-free 119-Ball BGA package and 165-Ball

FBGA package

• TQFP Available with 3-Chip Enable and 2-Chip Enable

• IEEE 1149.1 JTAG-Compatible Boundary Scan

•“ZZ” Sleep Mode option

Addresses and chip enables are registered at rising edge of

clock when either Address Strobe Processor (ADSP) or

Address Strobe Controller (ADSC) are active. Subsequent

burst addresses can be internally generated as controlled by

the Advance pin (ADV).

The CY7C1361C/CY7C1363C operates from a +3.3V core

power supply while all outputs may operate with either a +2.5

or +3.3V supply. All inputs and outputs are JEDEC-standard

JESD8-5-compatible.

places the SRAM in a power conservation “sleep” mode. Two

clock cycles are required to enter into or exit from this “sleep”

mode. While in this mode, data integrity is guaranteed.

Accesses pending when entering the “sleep” mode are not

considered valid nor is the completion of the operation

guaranteed. The device must be deselected prior to entering

6. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BW . Writes may occur only on subsequent clocks after

Test MODE SELECT (TMS)

IEEE 1149.1 Serial Boundary Scan (JTAG)

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.

The CY7C1361C/CY7C1363C incorporates a serial boundary

scan test access port (TAP) in the BGA package only. The

TQFP package does not offer this functionality. This part

operates in accordance with IEEE Standard 1149.1-1900, but

doesn’t have the set of functions required for full 1149.1

compliance. These functions from the IEEE specification are

excluded because their inclusion places an added delay in the

critical speed path of the SRAM. Note the TAP controller

functions in a manner that does not conflict with the operation

of other devices using 1149.1 fully compliant TAPs. The TAP

operates using JEDEC-standard 3.3V or 2.5V I/O logic levels.

Test Data-In (TDI)

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 CY7C1361C/CY7C1363C contains a TAP controller,

instruction register, boundary scan register, bypass register,

and ID register.

Test Data-Out (TDO)

Disabling the JTAG Feature

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.)

It is possible to operate the SRAM without using the JTAG

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

(V ) to prevent clocking of the device. TDI and TMS are inter-

nally pulled up and may be unconnected. They may alternately

be connected to V 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.

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

comes up in a High-Z state.

TAP Registers

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

rising edge of TCK.

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.

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.

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

EXTEST is a mandatory 1149.1 instruction which is to be

executed whenever the instruction register is loaded with all

0s. EXTEST is not implemented in this SRAM TAP controller,

and therefore this device is not compliant to 1149.1. The TAP

controller does recognize an all-0 instruction.

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.

Bypass Register

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

sometimes advantageous to skip certain chips. The bypass

SRAM with minimal delay. The bypass register is set LOW

When an EXTEST instruction is loaded into the instruction

instruction has been loaded. There is one difference between

the two instructions. Unlike the SAMPLE/PRELOAD

instruction, EXTEST places the SRAM outputs in a High-Z

state.

(V ) when the BYPASS instruction is executed.

Boundary Scan Register

IDCODE

The boundary scan register is connected to all the input and

bidirectional balls on the SRAM.

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.

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.

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 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.

SAMPLE Z

The SAMPLE Z instruction causes the boundary scan register

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

controller is in a Shift-DR state. It also places all SRAM outputs

into a High-Z state.

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.

SAMPLE/PRELOAD

SAMPLE/PRELOAD is a 1149.1-mandatory instruction. When

the SAMPLE/PRELOAD instructions are loaded into the in-

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

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

tured in the boundary scan register.

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 possi-

ble 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.

TAP Instruction Set

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.

The TAP controller used in this SRAM is not fully compliant to

the 1149.1 convention because some of the mandatory 1149.1

instructions are not fully implemented.

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

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.

The TAP controller cannot be used to load address data or

control signals into the SRAM and cannot preload the I/O

buffers. The SRAM does not implement the 1149.1 commands

EXTEST or INTEST or the PRELOAD portion of

SAMPLE/PRELOAD; rather, it performs a capture of the I/O

ring when these instructions are executed.

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 bound-

ary scan register between the TDI and TDO pins.

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

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.

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.

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.
