Features
Functional Description
■ Supports 133 MHz bus operations
The CY7C1381D/CY7C1383D/CY7C1383F is
a
3.3 V,
512 K × 36 and 1 M × 18 synchronous flow through SRAMs,
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 addresses, all data
inputs, address pipelining chip enable (CE1), depth-expansion
chip enables (CE2 and CE3), 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.

The CY7C1381D/CY7C1383D/CY7C1383F allows 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.

active, and (2) ADSP or ADSC is asserted LOW (if the access is
initiated by ADSC, the write inputs must be deasserted during
this first cycle). The address presented to the address inputs is
latched into the address register and the burst counter and/or
control logic, and later presented to the memory core. If the OE
input is asserted LOW, the requested data is available at the data
outputs with a maximum to tCDV after clock rise. ADSP is ignored
if CE1 is HIGH.
Functional Overview
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. Maximum access delay from the
clock rise (tCDV) is 6.5 ns (133 MHz device).
CY7C1381D/CY7C1383D/CY7C1383F supports secondary
cache in systems using 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 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.
Single Write Accesses Initiated by ADSP
This access is initiated when the following conditions are
satisfied at clock rise: (1) CE1, CE2, CE3 are all asserted active,
and (2) ADSP is asserted LOW. The addresses presented are
loaded into the address register and the burst inputs (GW, BWE,
and BWX) are ignored during this first clock cycle. If the write
inputs are asserted active (see Truth Table for Read/Write on
page 10 for appropriate states that indicate a write) on the next
clock rise, the appropriate data is latched and written into the
device. Byte writes are allowed. All I/O are tristated during a byte
write. As this is a common I/O device, the asynchronous OE
input signal must be deasserted and the I/O must be tristated
prior to the presentation of data to DQs. As a safety precaution,
the data lines are tristated when a write cycle is detected,
regardless of the state of OE.
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) and an
asynchronous output enable (OE) provide for easy bank
selection and output tristate control. ADSP is ignored if CE1 is
HIGH.
Single Write Accesses Initiated by ADSC
This write access is initiated when the following conditions are
satisfied at clock rise: (1) CE1, CE2, and CE3 are all asserted
active, (2) ADSC is asserted LOW, (3) ADSP is deasserted
HIGH, and (4) the write input signals (GW, BWE, and BWX)
indicate a write access. ADSC is ignored if ADSP is active LOW.
Single Read Accesses
A single read access is initiated when the following conditions
are satisfied at clock rise: (1) CE1, CE2, and CE3 are all asserted

into the specified address location. Byte writes are allowed. All
I/O are tristated when a write is detected, even a byte write.
Because this is a common I/O device, the asynchronous OE
input signal must be deasserted and the I/O must be tristated
prior to the presentation of data to DQs. As a safety precaution,
the data lines are tristated when a write cycle is detected,
regardless of the state of OE.

Burst Sequences
CY7C1381D/CY7C1383D/CY7C1383F provides an on-chip
two-bit wraparound burst counter inside the SRAM. The burst
counter is fed by A[1:0], and can follow either a linear or
interleaved burst order. The burst order is determined by the
state of the MODE input. A LOW on MODE selects a linear burst
sequence. A HIGH on MODE selects an interleaved burst order.
Leaving MODE unconnected causes the device to default to a
interleaved burst sequence.

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,

CY7C1383D

the rising edge of TCK. Data is output on the TDO ball on the
falling edge of TCK.
IEEE 1149.1 Serial Boundary Scan (JTAG)
The CY7C1381D/CY7C1383F incorporates a serial boundary
scan test access port (TAP). This part is fully compliant with
1149.1. The TAP operates using JEDEC-standard 3.3 V or 2.5 V
I/O logic levels.
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 14. 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.
CY7C1381D/CY7C1383F contains a TAP controller, instruction
register, boundary scan register, bypass register, and ID register.
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
may be left unconnected. At power up, the device comes up in a
reset state, which does not interfere with the operation of the
device.
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 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 allows data to be shifted through the
Test Access Port (TAP)
SRAM with minimal delay. The bypass register is set LOW (VSS
when the BYPASS instruction is executed.
)
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.
Boundary Scan Register
The boundary scan register is connected to all the input and
bidirectional balls on the SRAM.
Test Mode Select (TMS)
The boundary scan register is loaded with the contents of the
RAM input and output 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 input and output ring.
The TMS input is used to give commands to the TAP controller
and is sampled on the rising edge of TCK. This pin may be left
unconnected if the TAP is not used. The ball is pulled up
internally, resulting in a logic HIGH level.
Test Data-In (TDI)
The Boundary Scan Order on page 18 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.
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 the TAP Controller State
Diagram on page 13. 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.
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 17.
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 17).
The output changes on the falling edge of TCK. TDO is
connected to the least significant bit (LSB) of any register.
TAP Instruction Set
Overview
Performing a TAP Reset
Eight different instructions are possible with the three bit
instruction register. All combinations are listed in Instruction
Codes on page 17. Three of these instructions are listed as
RESERVED and must not be used. The other five instructions
are described in detail below.
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.
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 when it is shifted in, the TAP controller needs to
be moved into the Update-IR state.
TAP Registers
Registers are connected between the TDI and TDO balls and
allow data to be scanned in and out of the SRAM test circuitry.
Only one register can be selected at a time through the
instruction registers. Data is serially loaded into the TDI ball on
Document Number: 38-05544 Rev. *P
Page 11 of 37
CY7C1381D
CY7C1383D
CY7C1383F
EXTEST
still possible to capture all other signals and simply ignore the
value of the CK and CK captured in the boundary scan register.
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.
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 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.
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 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 is shifted in.
The IDCODE instruction is loaded into the instruction register
upon power up or whenever the TAP controller is given a test
logic reset state.
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.
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. The SAMPLE Z command places
all SRAM outputs into a high Z state.
EXTEST Output Bus Tri-State
IEEE standard 1149.1 mandates that the TAP controller be able
to put the output bus into a tristate mode.
SAMPLE/PRELOAD
The boundary scan register has a special bit located at bit #89
(for 165-ball FBGA package). When this scan cell, called the
“extest output bus tristate,” is latched into the preload register
during the Update-DR state in the TAP controller, it directly
controls the state of the output (Q-bus) pins, when the EXTEST
is entered as the current instruction. When HIGH, it enables the
output buffers to drive the output bus. When LOW, this bit places
the output bus into a high Z condition.
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 undergoes a
transition. The TAP may then try to capture a signal while in
transition (metastable state). This does not harm the device, but
there is no guarantee as to the value that is captured.
Repeatable results may not be possible.
This bit can be set by entering the SAMPLE/PRELOAD or
EXTEST command, and then shifting the desired bit into that cell,
during the Shift-DR state. During Update-DR, the value loaded
into that shift-register cell latches into the preload register. When
the EXTEST instruction is entered, this bit directly controls the
output Q-bus pins. Note that this bit is preset HIGH to enable the
output when the device is powered up, and also when the TAP
controller is in the Test-Logic-Reset state.
To guarantee that the boundary scan register captures 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
Reserved
These instructions are not implemented but are reserved for
future use. Do not use these instructions.

an internal pull-down resistor and hence
cannot be left floating externally by the user
during normal mode of operation.

For the 18M Ram9 (90 nm)
devices, there is no plan to fix
this issue.

1. ZZ Pin Issue
■ PROBLEM DEFINITION
The problem occurs only when the device is operated in the normal mode with ZZ pin left floating. The ZZ pin on the SRAM
device does not have an internal pull-down resistor. Switching noise in the system may cause the SRAM to recognize a HIGH
on the ZZ input, which may cause the SRAM to enter sleep mode. This could result in incorrect or undesirable operation of the
SRAM.
■ TRIGGER CONDITIONS
Device operated with ZZ pin left floating.
■ SCOPE OF IMPACT
When the ZZ pin is left floating, the device delivers incorrect data.
■ WORKAROUND
Tie the ZZ pin externally to ground.
■ FIX STATUS
Fix was done for the 72Mb RAM9 Synchronous SRAMs and 72M RAM9 NoBL SRAMs devices. Fixed devices have a new
revision. The following table lists the devices affected and the new revision after the fix.
2. JTAG Functionality
■ PROBLEM DEFINITION
The problem occurs only when the device is operated in the JTAG test mode.During this mode, the JTAG circuitry can perform
incorrectly by delivering the incorrect data or the incorrect scan chain length.
■ TRIGGER CONDITIONS
Several conditions can trigger this failure mode.
1. The device can deliver an incorrect length scan chain when operating in JTAG mode.
2. Some Byte Write inputs only recognize a logic HIGH level when in JTAG mode.
3. Incorrect JTAG data can be read from the device when the ZZ input is tied HIGH during JTAG operation.
■ SCOPE OF IMPACT
The device fails for JTAG test. This does not impact the normal functionality of the device.
■ WORKAROUND
1.Perform JTAG testing with these devices in “BYPASS mode”.
2.Do not use JTAG test.

3. Chip Enable Issue
■ PROBLEM DEFINITION
The die used for CY7C138*D has three Chip Enables, CE1#, CE2 and CE3#. The devices having part numbers CY7C138*D
(with 119-ball BGA package option only) utilize a single Chip Enable (CE1#) signal. CE2 and CE3# signals which are unused
should be internally connected to Vcc and Ground respectively to keep them in “enabled” state, thus allowing CE1# to have
full control of the chip. The internal Chip Enable CE3# pad is floating instead of being tied to Ground. This state of CE3# signal
can result in incorrect or undesirable operation of the SRAM.
■ TRIGGER CONDITIONS
There are no specific trigger conditions. The issue can occur at any time during the normal operation of the device.
■ SCOPE OF IMPACT
This issue affects the normal functionality, and can cause unstable operation of the device.
■ WORKAROUND
Use the fixed revision of the device.
■ FIX STATUS
Fix was done for all the devices having this issue and was involved re-design of the substrate in order to have CE2 and CE3#
pads bonded to Vcc and Ground lines respectively in the substrate. Fixed devices have a new revision. The following table lists
the devices affected and the new revision after the fix.
