The CY7C1360C/CY7C1362C SRAM integrates 256 K × 36 and
512 K × 18 SRAM cells with advanced 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 (CE1), depth-expansion chip enables (CE2 and
CE3[1]), burst control inputs (ADSC, ADSP, and ADV), write
enables (BWX, and BWE), and global write (GW). Asynchronous
inputs include the output enable (OE) and the ZZ pin.
Addresses and chip enables are registered at the 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).
Address, data inputs, and write controls are registered on-chip
to initiate a self-timed write cycle.This part supports byte write
operations (see Pin Definitions on page 8 and Truth Table on
page 11 for further details). Write cycles can be one to two or four
bytes wide as controlled by the byte write control inputs. GW
when active LOW causes all bytes to be written.
The CY7C1360C/CY7C1362C operate from a +3.3 V core power
supply while all outputs may operate with either a +2.5 or +3.3 V
supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.

Description
A0, A1, A
InputAddress inputs used to select one of the address locations. Sampled at the rising edge of the CLK
synchronous if ADSP or ADSC is active LOW, and CE1, CE2, and CE3[2]are sampled active. A1:A0 are fed to the
two-bit counter.
BWA, BWB,
BWC, BWD
InputByte write select inputs, active LOW. Qualified with BWE to conduct byte writes to the SRAM. Sampled
synchronous on the rising edge of CLK.
GW
InputGlobal write enable input, active LOW. When asserted LOW on the rising edge of CLK, a global write
synchronous is conducted (all bytes are written, regardless of the values on BWX and BWE).
BWE
InputByte write enable input, active LOW. Sampled on the rising edge of CLK. This signal must be asserted
synchronous LOW to conduct a byte write.
CLK
Inputclock
Clock input. Used to capture all synchronous inputs to the device. Also used to increment the burst
counter when ADV is asserted LOW, during a burst operation.
CE1
InputChip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE2
synchronous and CE3[2] to select/deselect the device. ADSP is ignored if CE1 is HIGH. CE1 is sampled only when a
new external address is loaded.
CE2
InputChip enable 2 input, active HIGH. Sampled on the rising edge of CLK. Used in conjunction with CE1
synchronous and CE3[2] to select/deselect the device. CE2 is sampled only when a new external address is loaded.
CE3[2]
InputChip enable 3 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE1
synchronous and CE2 to select/deselect the device. Not available for AJ package version. Not connected for BGA.
Where referenced, CE3[2] is assumed active throughout this document for BGA. CE3 is sampled only
when a new external address is loaded.
OE
InputOutput enable, asynchronous input, active LOW. Controls the direction of the I/O pins. When LOW,
asynchronous the I/O pins behave as outputs. When deasserted HIGH, I/O pins are tristated, and act as input data
pins. OE is masked during the first clock of a read cycle when emerging from a deselected state.
ADV
InputAdvance input signal, sampled on the rising edge of CLK, active LOW. When asserted, it
synchronous automatically increments the address in a burst cycle.
ADSP
InputAddress strobe from processor, sampled on the rising edge of CLK, active LOW. When asserted
synchronous LOW, addresses presented to the device are captured in the address registers. A1:A0 are also loaded
into the burst counter. When ADSP and ADSC are both asserted, only ADSP is recognized. ASDP is
ignored when CE1 is deasserted HIGH.
ADSC
InputAddress strobe from controller, sampled on the rising edge of CLK, active LOW. When asserted
synchronous LOW, addresses presented to the device are captured in the address registers. A1:A0 are also loaded
into the burst counter. When ADSP and ADSC are both asserted, only ADSP is recognized.
ZZ
InputZZ “sleep” input, active HIGH. When asserted HIGH places the device in a non-time-critical “sleep”
asynchronous condition with data integrity preserved. For normal operation, this pin has to be LOW or left floating. ZZ
pin has an internal pull-down.
DQs, DQPX
I/OBidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the
synchronous rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the
addresses presented during the previous clock rise of the read cycle. The direction of the pins is
controlled by OE. When OE is asserted LOW, the pins behave as outputs. When HIGH, DQs and DQPX
are placed in a tristate condition.
VDD
Power supply Power supply inputs to the core of the device.
VSS
Ground
Ground for the core of the device.
VSSQ
I/O ground
Ground for the I/O circuitry.
VDDQ
I/O power
supply
Power supply for the I/O circuitry.
MODE
Inputstatic
Selects burst order. When tied to GND selects linear burst sequence. When tied to VDD or left floating
selects interleaved burst sequence. This is a strap pin and should remain static during device operation.
Mode pin has an internal pull-up.
Note
2. CE3 is for A version of 100-pin TQFP (3 Chip Enable option) and 165-ball FBGA package only. 119-ball BGA is offered only in 2 Chip Enable.

Functional Overview
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. All data outputs pass through output
registers controlled by the rising edge of the clock. Maximum
access delay from the clock rise (tCO) is 3.0 ns (200 MHz device).
The CY7C1360C/CY7C1362C supports secondary cache in
systems using either a linear or interleaved burst sequence. The
interleaved burst order supports Pentium and i486 processors.
The linear burst sequence is suited for processors that use a
linear burst sequence. The burst order is user selectable, and is
determined by sampling the MODE input. Accesses can be
initiated with either the processor address strobe (ADSP) or the
controller address strobe (ADSC). Address advancement
through the burst sequence is controlled by the ADV input. A
two-bit on-chip wraparound burst counter captures the first
address in a burst sequence and automatically increments the
address for the rest of the burst access.
Byte write operations are qualified with the byte write enable
(BWE) and byte write select (BWX) inputs. A global write enable
(GW) overrides all byte write inputs and writes data to all four
bytes. All writes are simplified with on-chip synchronous
self-timed write circuitry.
Three synchronous chip selects (CE1, CE2, CE3[3]) and an
asynchronous output enable (OE) provide for easy bank
selection and output tristate control. ADSP is ignored if CE1 is
HIGH.
Single Read Accesses
This access is initiated when the following conditions are
satisfied at clock rise: (1) ADSP or ADSC is asserted LOW,
(2) CE1, CE2, CE3[3] are all asserted active, and (3) the write
signals (GW, BWE) are all deasserted HIGH. ADSP is ignored if
CE1 is HIGH. The address presented to the address inputs (A)
is stored into the address advancement logic and the address
register while being presented to the memory array. The
corresponding data is allowed to propagate to the input of the
output registers. At the rising edge of the next clock, the data is
allowed to propagate through the output register and on the data
bus within 3.0 ns (200 MHz device) if OE is active LOW. The only
exception occurs when the SRAM is emerging from a deselected
state to a selected state, its outputs are always tristated during
the first cycle of the access. After the first cycle of the access,
the outputs are controlled by the OE signal. Consecutive single
read cycles are supported. After the SRAM is deselected at clock
rise by the chip select and either ADSP or ADSC signals, its
output tristates immediately.
Single Write Accesses Initiated by ADSP
This access is initiated when both of the following conditions are
satisfied at clock rise: (1) ADSP is asserted LOW and (2) CE1,
CE2, CE3[3] are all asserted active. The address presented to A
is loaded into the address register and the address advancement
logic while being delivered to the memory array. The write signals
(GW, BWE, and BWX) and ADV inputs are ignored during this
first cycle.
ADSP-triggered write accesses require two clock cycles to
complete. If GW is asserted LOW on the second clock rise, the
data presented to the DQs inputs is written into the
corresponding address location in the memory array. If GW is
HIGH, then the write operation is controlled by BWE and BWX
signals. The CY7C1360C/CY7C1362C provides byte write
capability that is described in the Write Cycle Descriptions table.
Asserting the byte write enable input (BWE) with the selected
byte write (BWX) input, will selectively write to only the desired
bytes. Bytes not selected during a byte write operation remain
unaltered. A synchronous self-timed write mechanism has been
provided to simplify the write operations.
Because the CY7C1360C/CY7C1362C is a common I/O device,
the output enable (OE) must be deasserted HIGH before
presenting data to the DQs inputs. Doing so tristates the output
drivers. As a safety precaution, DQs are automatically tristated
whenever a Write cycle is detected, regardless of the state of OE.

Single Write Accesses Initiated by ADSC
Sleep Mode
ADSC write accesses are initiated when the following conditions
are satisfied: (1) ADSC is asserted LOW, (2) ADSP is deasserted
HIGH, (3) CE1, CE2, CE3[4] are all asserted active, and (4) the
appropriate combination of the write inputs (GW, BWE, and
BWX) are asserted active to conduct a write to the desired
byte(s). ADSC-triggered write accesses require a single clock
cycle to complete. The address presented to A is loaded into the
address register and the address advancement logic while being
delivered to the memory array. The ADV input is ignored during
this cycle. If a global write is conducted, the data presented to
the DQs is written into the corresponding address location in the
memory core. If a byte write is conducted, only the selected bytes
are written. Bytes not selected during a byte write operation
remains unaltered. A synchronous self-timed write mechanism
has been provided to simplify the write operations.
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. 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. CE1, CE2,
CE3[4], ADSP, and ADSC must remain inactive for the duration
of tZZREC after the ZZ input returns LOW.
Because the CY7C1360C/CY7C1362C is a common I/O device,
the output enable (OE) must be deasserted HIGH before
presenting data to the DQs inputs. Doing so tristates the output
drivers. As a safety precaution, DQs are automatically tristated
whenever a write cycle is detected, regardless of the state of OE.
Burst Sequences
The CY7C1360C/CY7C1362C provides a two-bit wraparound
counter, fed by A1:A0, that implements either an interleaved or
linear burst sequence. The interleaved burst sequence is
designed specifically to support Intel Pentium applications. The
linear burst sequence is designed to support processors that
follow a linear burst sequence. The burst sequence is user
selectable through the MODE input.
Asserting ADV LOW at clock rise automatically increments the
burst counter to the next address in the burst sequence. Both
read and write burst operations are supported.

Notes
5. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
6. WRITE = L when any one or more byte write enable signals and BWE = L or GW = L. WRITE = H when all byte write enable signals, BWE, GW = H.
7. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
8. CE1, CE2, and CE3 are available only in the TQFP package. BGA package has only two chip selects CE1 and CE2.
9. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BWX. Writes may occur only on subsequent clocks after the
ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH prior to the start of the Write cycle to allow the outputs to tri-state. OE is a don't care for
the remainder of the write cycle.
10. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle all data bits are tri-State when OE is inactive
or when the device is deselected, and all data bits behave as output when OE is active (LOW).

CY7C1360C, CY7C1362C
IEEE 1149.1 Serial Boundary Scan (JTAG)
TAP Registers
The CY7C1360C 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 does not 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 that 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 3.3
V or 2.5 V I/O logic levels.
The CY7C1360C contains a TAP controller, instruction register,
boundary scan register, bypass register, and ID register.
Registers are connected between the TDI and TDO balls and
enable 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.
Disabling the JTAG Feature
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
alternately be connected to VDD through a pull-up resistor. TDO
should be left unconnected. Upon power-up, the device comes
up in a reset state which does not interfere with the operation of
the device.
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.
Test Mode Select (TMS)
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.
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. For information on
loading the instruction register, see TAP Controller State
Diagram on page 15. TDI is internally pulled up and can be
unconnected if the TAP is unused in an application. TDI is
connected to the most significant bit (MSB) of any register.
Test Data-Out (TDO)
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 (see Instruction Codes on page 19).
The output changes on the falling edge of TCK. TDO is
connected to the least significant bit (LSB) of any register.
Performing a TAP Reset
A RESET is performed by forcing TMS HIGH (VDD) for five rising
edges of TCK. This RESET does not affect the operation of the
SRAM and may be performed while the SRAM is operating.
At power-up, the TAP is reset internally to ensure that TDO
comes up in a high Z state.
Document Number: 38-05540 Rev. *N
Instruction Register
Three-bit instructions can be serially loaded into the instruction
register. This register is loaded when it is placed between the TDI
and TDO balls as shown in the TAP Controller Block Diagram on
page 16. 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.
When the TAP controller is in the Capture-IR state, the two least
significant bits are loaded with a binary “01” pattern to enable
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
register is a single-bit register that can be placed between the
TDI and TDO balls. This enables data to be shifted through the
SRAM with minimal delay. The bypass register is set LOW (VSS)
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 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 Boundary Scan Order on page 20 and Boundary Scan Order
on page 21 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.
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 Identification Register Definitions on
page 19.
TAP Instruction Set
Overview
Eight different instructions are possible with the three-bit
instruction register. All combinations are listed in Instruction
Codes on page 19. Three of these instructions are listed as
RESERVED and should not be used. The other five instructions
are described in detail in this section.
Page 13 of 37
CY7C1360C, CY7C1362C
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.
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.
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
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 an EXTEST instruction is loaded into the instruction
register, the SRAM responds as if a SAMPLE/PRELOAD
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.
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.
The IDCODE instruction is loaded into the instruction register
upon power up or whenever the TAP controller is given a test
logic reset state.
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.
Document Number: 38-05540 Rev. *N
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.
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.
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 setup plus hold
times (tCS and tCH). 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.
After 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 enables 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.
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.
BYPASS
When the BYPASS instruction is loaded in the instruction register
and the TAP is placed in a Shift-DR state, the bypass register is
placed between the TDI and TDO balls. The advantage of the
BYPASS instruction is that it shortens the boundary scan path
when multiple devices are connected together on a board.
Reserved
These instructions are not implemented but are reserved for
future use. Do not use these instructions.

Notes
20. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V.
21. Test conditions shown in (a) of Figure 5 on page 24 unless otherwise noted.
22. This part has a voltage regulator internally; tPOWER is the time that the power needs to be supplied above VDD(minimum) initially before a read or write operation can
be initiated.
23. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of Figure 5 on page 24. Transition is measured ± 200 mV from steady-state voltage.
24. At any given voltage and temperature, tOEHZ is less than tOELZ and tCHZ is less than tCLZ to eliminate bus contention between SRAMs when sharing the same data
bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed to achieve
high Z prior to low Z under the same system conditions.
25. This parameter is sampled and not 100% tested.
