256K x 36/512K x 18 Synchronous
Flow-Thru Burst SRAM
synchronous peripheral circuitry and a two-bit counter for
internal burst operation. All synchronous inputs are gated by
registers controlled by a positive-edge-triggered Clock Input
(CLK). The synchronous inputs include all addresses, all data
inputs, address-pipelining Chip Enable (CE), depth-expansion
Chip Enables (CE2 and CE2), burst control inputs (ADSC,
ADSP, and ADV), Write Enables (BWa, BWb, BWc, BWd, and
BWE), and global Write (GW). However, the CE2 chip enable
input is only available for the TA package version.
Features
• Fast access times: 6.0, 6.5, 7.0, and 8.0ns
• Fast clock speed: 150, 133, 117, and 100MHz
• Fast OE access times: 3.5 ns and 4.0 ns
• Optimal for depth expansion (one cycle chip deselect
to eliminate bus contention)
• 3.3V –5% and +10% power supply
• 3.3V or 2.5V I/O supply
• 5V tolerant inputs except I/Os
• Clamp diodes to VSS at all inputs and outputs
• Common data inputs and data outputs
• Byte Write Enable and Global Write control
• Multiple chip enables for depth expansion: A package
version and two chip enables for BG and AJ package
versions
Asynchronous inputs include the Output Enable (OE) and
burst mode control (MODE). The data outputs (Q), enabled by
OE, are also asynchronous.
Addresses and chip enables are registered with either
Address Status Processor (ADSP) or Address Status
Controller (ADSC) input pins. Subsequent burst addresses
can be internally generated as controlled by the Burst Advance
Pin (ADV).
• Address pipeline capability
• Address, data, and control registers
• Internally self-timed Write cycle
• Burst control pins (interleaved or linear burst
sequence)
• Automatic power-down feature available using ZZ
mode or CE deselect.
• JTAG boundary scan for BG and AJ package version
• Low-profile 119-bump 14-mm × 22-mm PBGA (Ball Grid
Array) and 100-pin TQFP packages
Address, data inputs, and Write controls are registered on-chip
to initiate self-timed Write cycle. Write cycles can be one to
four bytes wide as controlled by the Write control inputs.
Individual byte Write allows individual byte to be written. BWa
controls DQa. BWb controls DQb. BWc controls DQc. BWd
controls DQd. BWa, BWb, BWc, and BWd can be active only
with BWE being LOW. GW being LOW causes all bytes to be
written. The x18 version only has 18 data inputs/outputs (DQa
and DQb) along with BWa and BWb (no BWc, BWd, DQc, and
DQd).
For the B and T package versions, four pins are used to
implement JTAG test capabilities: Test Mode Select (TMS),
Test Data-In (TDI), Test Clock (TCK), and Test Data-Out
(TDO). The JTAG circuitry is used to serially shift data to and
from the device. JTAG inputs use LVTTL/LVCMOS levels to
shift data during this testing mode of operation. The TA
package version does not offer the JTAG capability.
Functional Description
The Cypress Synchronous Burst SRAM family employs
high-speed, low-power CMOS designs using advanced
triple-layer polysilicon, double-layer metal technology. Each
memory cell consists of four transistors and two high-valued
resistors.
The CY7C1361A and CY7C1363A operate from a +3.3V
power supply. All inputs and outputs are LVTTL-compatible.
The CY7C1361A and CY7C1363A SRAMs integrate 262,144
× 36 and 524,288 × 18 SRAM cells with advanced

Notes:
3. X = “Don’t Care.” H = logic HIGH. L = logic LOW.
For X36 product, Write = L means [BWE + BWa*BWb*BWc*BWd]*GW equals LOW. Write = H means [BWE + BWa*BWb*BWc*BWd]*GW equals HIGH.
For X18 product, Write = L means [BWE + BWa*BWb]*GW equals LOW. Write = H means [BWE + BWa*BWb]*GW equals HIGH.
4. BWa enables Write to DQa. BWb enables Write to DQb. BWc enables Write to DQc. BWd enables Write to DQd.
5. All inputs except OE must meet set-up and hold times around the rising edge (LOW to HIGH) of CLK.
6. Suspending burst generates wait cycle.l
7. For a Write operation following a Read operation, OE must be HIGH before the input data required set-up time plus High-Z time for OE and staying HIGH
throughout the input data hold time.
8. This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
9. ADSP LOW along with chip being selected always initiates a Read cycle at the L-H edge of CLK. A Write cycle can be performed by setting Write LOW for the
CLK L-H edge of the subsequent wait cycle. Refer to Write timing diagram for clarification.

Sleep Mode
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
the “sleep” mode. CEs, ADSP, and ADSC must remain inactive
for the duration of tZZREC after the ZZ input returns LOW.
The ZZ input pin is an asynchronous input. Asserting ZZ
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.

TMS–Test Mode Select (INPUT)
IEEE 1149.1 Serial Boundary Scan (JTAG)
The TMS input is sampled on the rising edge of TCK. This is
the command input for the TAP controller state machine. It is
allowable to leave this pin unconnected if the TAP is not used.
The pin is pulled up internally, resulting in a logic HIGH level.
Overview
This device incorporates a serial boundary scan test access
port (TAP). This port is designed to operate in a manner
consistent with IEEE Standard 1149.1-1990 (commonly
referred to as JTAG), but does not implement all of the
functions required for IEEE 1149.1 compliance. Certain
functions have been modified or eliminated because their
implementation places extra delays in the critical speed path
of the device. Nevertheless, the device supports the standard
TAP controller architecture (the TAP controller is the state
machine that controls the TAPs operation) and can be
expected to function in a manner that does not conflict with the
operation of devices with IEEE Standard 1149.1 compliant
TAPs. The TAP operates using LVTTL/ LVCMOS logic level
signaling.
TDI–Test Data In (INPUT)
The TDI input is sampled on the rising edge of TCK. This is the
input side of the serial registers placed between TDI and TDO.
The register placed between TDI and TDO is determined by
the state of the TAP controller state machine and the
instruction that is currently loaded in the TAP instruction
register (refer to Figure 1, TAP Controller State Diagram). It is
allowable to leave this pin unconnected if it is not used in an
application. The pin is pulled up internally, resulting in a logic
HIGH level. TDI is connected to the Most Significant Bit (MSB)
of any register (see Figure 2).
Disabling the JTAG Feature
TDO–Test Data Out (OUTPUT)
It is possible to use this device without using the JTAG feature.
To disable the TAP controller without interfering with normal
operation of the device, TCK should be tied LOW (VSS) to
prevent clocking the device. TDI and TMS are internally pulled
up and may be unconnected. They may alternately be pulled
up to VCC through a 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 pin is used to serially clock data-out from the
registers. The output that is active depending on the state of
the TAP state machine (refer to Figure 1, TAP Controller State
Diagram). Output changes in response to the falling edge of
TCK. This is the output side of the serial registers placed
between TDI and TDO. TDO is connected to the Least Signif-
icant Bit (LSB) of any register (see Figure 2).
Performing a TAP Reset
Test Access Port
The TAP circuitry does not have a reset pin (TRST, which is
optional in the IEEE 1149.1 specification). A RESET can be
performed for the TAP controller by forcing TMS HIGH (VCC)
for five rising edges of TCK and pre-loads the instruction
register with the IDCODE command. This type of reset does
not affect the operation of the system logic. The reset affects
test logic only.
TCK–Test Clock (INPUT)
Clocks all TAP events. All inputs are captured on the rising
edge of TCK and all outputs propagate from the falling edge
of TCK.
At power-up, the TAP is reset internally to ensure that TDO is
in a High-Z state.
Note:
10. For the X18 product, there are only BWa and BWb.

TAP Registers
TAP Controller Instruction Set
Overview
Overview
The various TAP registers are selected (one at a time) via the
sequences of ones and zeros input to the TMS pin as the TCK
is strobed. Each of the TAPs registers are serial shift registers
that capture serial input data on the rising edge of TCK and
push serial data out on subsequent falling edge of TCK. When
a register is selected, it is connected between the TDI and
TDO pins.
There are two classes of instructions defined in the IEEE
Standard 1149.1-1990; the standard (public) instructions and
device specific (private) instructions. Some public instructions
are mandatory for IEEE 1149.1 compliance. Optional public
instructions must be implemented in prescribed ways.
Although the TAP controller in this device follows the IEEE
1149.1 conventions, it is not IEEE 1149.1-compliant because
some of the mandatory instructions are not fully implemented.
The TAP on this device may be used to monitor all input and
I/O pads, but can not be used to load address, data, or control
signals into the device or to preload the I/O buffers. In other
words, the device will not perform IEEE 1149.1 EXTEST,
INTEST, or the preload portion of the SAMPLE/PRELOAD
command.
Instruction Register
The instruction register holds the instructions that are
executed by the TAP controller when it is moved into the run
test/idle or the various data register states. The instructions
are three bits long. The register can be loaded when it is
placed between the TDI and TDO pins. The parallel outputs of
the instruction register are automatically preloaded with the
IDCODE instruction upon power-up or whenever the controller
is placed in the test-logic reset state. When the TAP controller
is in the Capture-IR state, the two least significant bits of the
serial instruction register are loaded with a binary “01” pattern
to allow for fault isolation of the board-level serial test data
path.
When the TAP controller is placed in Capture-IR state, the two
least significant bits of the instruction register are loaded with
01. When the controller is moved to the Shift-IR state the
instruction is serially loaded through the TDI input (while the
previous contents are shifted out at TDO). For all instructions,
the TAP executes newly loaded instructions only when the
controller is moved to Update-IR state. The TAP instruction
sets for this device are listed in the following tables.
Bypass Register
The bypass register is a single-bit register that can be placed
between TDI and TDO. It allows serial test data to be passed
through the device TAP to another device in the scan chain
with minimum delay. The bypass register is set LOW (VSS)
when the BYPASS instruction is executed.
EXTEST
EXTEST is an IEEE 1149.1 mandatory public instruction. It is
to be executed whenever the instruction register is loaded with
all 0s. EXTEST is not implemented in this device.
The TAP controller does recognize an all-0 instruction. When
an EXTEST instruction is loaded into the instruction register,
the device responds as if a SAMPLE/PRELOAD instruction
has been loaded. There is one difference between two instruc-
tions. Unlike SAMPLE/PRELOAD instruction, EXTEST places
the device outputs in a High-Z state.
Boundary Scan Register
The Boundary Scan register is connected to all the input and
bidirectional I/O pins (not counting the TAP pins) on the device.
This also includes a number of NC pins that are reserved for
future needs. There are a total of 70 bits for the x36 device and
51 bits for the x18 device. The boundary scan register, under
the control of the TAP controller, is loaded with the contents of
the device I/O ring when the controller is in Capture-DR state
and then is placed between the TDI and TDO pins when the
controller is moved to Shift-DR state. The EXTEST,
SAMPLE/PRELOAD and SAMPLE-Z instructions can be used
to capture the contents of the I/O ring.
IDCODE
The IDCODE instruction causes a vendor-specific, 32-bit code
to be loaded into the ID register when the controller is in
Capture-DR mode and places the ID register between the TDI
and TDO pins in Shift-DR mode. The IDCODE instruction is
the default instruction loaded in the instruction upon power-up
and at any time the TAP controller is placed in the test-logic
reset state.
The Boundary Scan Order table describes the order in which
the bits are connected. The first column defines the bit’s
position in the boundary scan register. The MSB of the register
is connected to TDI, and LSB is connected to TDO. The
second column is the signal name, the third column is the
TQFP pin number, and the fourth column is the BGA bump
number.
SAMPLE-Z
If the High-Z instruction is loaded in the instruction register, all
output pins are forced to a High-Z state and the boundary scan
register is connected between TDI and TDO pins when the
TAP controller is in a Shift-DR state.
Identification (ID) Register
SAMPLE/PRELOAD
The ID Register is a 32-bit register that is loaded with a device
and vendor specific 32-bit code when the controller is put in
Capture-DR state with the IDCODE command loaded in the
instruction register. The register is then placed between the
TDI and TDO pins when the controller is moved into Shift-DR
state. Bit 0 in the register is the LSB and the first to reach TDO
when shifting begins. The code is loaded from a 32-bit on-chip
ROM. It describes various attributes of the device as described
in the Identification Register Definitions table.
SAMPLE/PRELOAD is an IEEE 1149.1 mandatory instruction.
The PRELOAD portion of the command is not implemented in
this device, so the device TAP controller is not fully IEEE
1149.1-compliant.
When the SAMPLE/PRELOAD instruction is loaded in the
instruction register and the TAP controller is in the Capture-DR
state, a snap shot of the data in the device’s input and I/O
buffers is loaded into the boundary scan register. Because the
device system clock(s) are independent from the TAP clock
Document #: 38-05259 Rev. *A
Page 10 of 26
CY7C1361A
CY7C1363A
(TCK), it is possible for the TAP to attempt to capture the input
and I/O ring contents while the buffers are in transition (i.e., in
a metastable state). Although allowing the TAP to sample
metastable inputs will not harm the device, repeatable results
can not be expected. To guarantee that the boundary scan
register will capture the correct value of a signal, the device
input signals must be stabilized long enough to meet the TAP
controller’s capture set-up plus hold time (tCS plus tCH). The
device clock input(s) need not be paused for any other TAP
operation except capturing the input and I/O ring contents into
the boundary scan register.
state with the SAMPLE/PRELOAD instruction loaded in the
instruction register has the same effect as the Pause-DR
command.
BYPASS
When the BYPASS instruction is loaded in the instruction
register and the TAP controller is in the Shift-DR state, the
bypass register is placed between TDI and TDO. This allows
the board level scan path to be shortened to facilitate testing
of other devices in the scan path.
Reserved
Moving the controller to Shift-DR state then places the
boundary scan register between the TDI and TDO pins.
Because the PRELOAD portion of the command is not imple-
mented in this device, moving the controller to the Update-DR
Do not use these instructions. They are reserved for future
use.

18. TA is the case temperature.
19. The ground level at the start of “power on” on the VCC pins should be no greater than 200mV.
20. Overshoot: VIH < + 6.0V for t < tKC /2; undershoot: VIL < – 2.0V for t < tKC /2.
21. Output loading is specified with CL=5 pF as in AC Test Loads.
22.
ICC is given with no output current. ICC increases with greater output loading and faster cycle times.
23. “Device Deselected” means the device is in power-down mode as defined in the truth table. “Device Selected” means the device is active.
24. Typical values are measured at 3.3V, 25°C, and 20-ns cycle time.
