Functional Description
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
SRAM[1] integrates 512 K × 36/1 M × 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 [2]), 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 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 on page 4 and Truth Table on page 11 for further
details). Write cycles can be one to four bytes wide as controlled
by the byte write control inputs. GW active LOW causes all bytes
to be written. This device incorporates an additional pipelined
enable register which delays turning off the output buffers an
additional cycle when a deselect is executed.This feature allows
depth expansion without penalizing system performance.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
operates from a +3.3 V core power supply while all outputs
operate with a +3.3 V or +2.5 V supply. All inputs and outputs are
JEDEC-standard and JESD8-5-compatible.

Name I/O Description
A0, A1, A Input-
Synchronous
Address inputs used to select one of the address locations. Sampled at the rising edge of the CLK
if ADSP or ADSC is active LOW, and CE1, CE2, and CE3 [4] are sampled active. A1: A0 are fed to the
two-bit counter.
BWA, BWB,
BWC, BWD
Input-
Synchronous
Byte write select inputs, active LOW. Qualified with BWE to conduct byte writes to the SRAM. Sampled
on the rising edge of CLK.
GW Input-
Synchronous
Global write enable input, active LOW. When asserted LOW on the rising edge of CLK, a global write
is conducted (all bytes are written, regardless of the values on BWX and BWE).
BWE Input-
Synchronous
Byte write enable input, active LOW. Sampled on the rising edge of CLK. This signal must be asserted
LOW to conduct a byte write.
CLK Input-
Clock
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.
CE1Input-
Synchronous
Chip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE2
and CE3 [4] to select or deselect the device. ADSP is ignored if CE1 is HIGH. CE1 is sampled only when
a new external address is loaded.
CE2 [4] Input-
Synchronous
Chip enable 2 input, active HIGH. Sampled on the rising edge of CLK. Used in conjunction with CE1
and CE3[4] to select or deselect the device. CE2 is sampled only when a new external address is loaded.
CE3 [4] Input-
Synchronous
Chip enable 3 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE1
and CE2 to select or deselect the device. Not connected for BGA. Where referenced, CE3 [4] is assumed
active throughout this document for BGA. CE3 is sampled only when a new external address is loaded.
OE Input-
Asynchronous
Output enable, asynchronous input, active LOW. Controls the direction of the I/O pins. When LOW,
the I/O pins behave as outputs. When deasserted HIGH, DQ 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 Input-
Synchronous
Advance input signal, sampled on the rising edge of CLK, active LOW. When asserted, it
automatically increments the address in a burst cycle.
ADSP Input-
Synchronous
Address strobe from processor, sampled on the rising edge of CLK, active LOW. When asserted
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 Input-
Synchronous
Address strobe from controller, sampled on the rising edge of CLK, active LOW. When asserted
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 Input-
Asynchronous
ZZ sleep input, active HIGH. When asserted HIGH places the device in a non-time critical sleep
condition with data integrity preserved. For normal operation, this pin has to be LOW. ZZ pin has an
internal pull down.
DQs,
DQPX
I/O-
Synchronous
Bidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the
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.

CY7C1387D, CY7C1387F
Document Number: 38-05545 Rev. *H Page 8 of 36
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.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
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.
Synchronous chip selects CE1, CE2, CE3 [5] 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)
chip selects 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 is stored into the
address advancement logic and the address register while being
presented to the memory core. 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 onto the data bus within tCO 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.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a
double cycle deselect part. After the SRAM is deselected at clock
rise by the chip select and either ADSP or ADSC signals, its
output tristates immediately after the next clock rise.
MODE Input-
Static
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 must remain static during device operation.
Mode pin has an internal pull up.
TDO JTAG serial
output
Synchronous
Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK. If the JTAG feature is
not used, this pin must be disconnected. This pin is not available on TQFP packages.
TDI JTAG serial
input
Synchronous
Serial data-in to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is not used,
this pin can be disconnected or connected to VDD. This pin is not available on TQFP packages.
TMS JTAG serial
input
Synchronous
Serial data-in to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is not used,
this pin can be disconnected or connected to VDD. This pin is not available on TQFP packages.
TCK JTAG-

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) chip
select is asserted active. The address presented is loaded into
the address register and the address advancement logic while
being delivered to the memory core. 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 DQx inputs is written into the
corresponding address location in the memory core. If GW is
HIGH, the write operation is controlled by BWE and BWX signals.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
provides byte write capability that is described in the write cycle
description table. Asserting the byte write enable input (BWE)
with the selected byte write input, selectively writes to the desired
bytes. 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 CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a
common I/O device, the output enable (OE) must be deasserted
HIGH before presenting data to the DQ inputs. This tristates the
output drivers. As a safety precaution, DQ are automatically
tristated whenever a write cycle is detected, regardless of the
state of OE.
Single Write Accesses Initiated by ADSC
ADSC write accesses are initiated when the following conditions
are satisfied: (1) ADSC is asserted LOW, (2) ADSP is deasserted
HIGH, (3) chip select is 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 is loaded into the address register and
the address advancement logic while being delivered to the
memory core. The ADV input is ignored during this cycle. If a
global write is conducted, the data presented to the DQX 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.

Burst Sequences
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
provides a two-bit wraparound counter, fed by A[1:0], 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.
Sleep Mode
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. CEs, ADSP, and
ADSC must remain inactive for the duration of tZZREC after the
ZZ input returns LOW.

Notes
6. X = Do not care, H = Logic HIGH, L = Logic LOW.
7. 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.
8. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
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 tristate. 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 tristate when OE is inactive
or when the device is deselected, and all data bits behave as output when OE is active (LOW).

IEEE 1149.1 Serial Boundary Scan (JTAG)
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
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.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
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
can 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. 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 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 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. 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.
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.
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 15. 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 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
register is a single-bit register that can be placed between the
TDI and TDO balls. This allows 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 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 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.
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 on
page 18.
TAP Instruction Set
Overview
Eight different instructions are possible with the three bit
instruction register. All combinations are listed in Identification
Codes on page 18. Three of these instructions are listed as
RESERVED and must not be used. The other five instructions
are described in detail below.
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 after 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.
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. The SAMPLE Z command places
all SRAM outputs into a high Z state.
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 input 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. As 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.
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
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 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.
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.
EXTEST Output Bus Tristate
IEEE Standard 1149.1 mandates that the TAP controller be able
to put the output bus into a tristate mode.
The boundary scan register has a special bit located at bit #85
(for 119-ball BGA package) or 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.
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.
Reserved
These instructions are not implemented but are reserved for
future use. Do not use these instructions.

Notes
24. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V.
25. Test conditions shown in (a) of Figure 4 on page 23 unless otherwise noted.
26. 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.
27. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in (b) of Figure 4 on page 23. Transition is measured ±200 mV from steady-state voltage.
28. At any 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.
29. This parameter is sampled and not 100% tested.
