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

Asynchronous inputs include the output enable (OE) and the ZZ
pin.
■ 2.5 V or 3.3 V I/O power supply (VDDQ)
■ Fast clock-to-output times

strobe controller (ADSC) are active. Subsequent burst
addresses can be internally generated as controlled by the
advance pin (ADV).
■ Provides high performance 3-1-1-1 access rate
■ User selectable burst counter supporting Intel Pentium
Interleaved or linear burst sequences
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 Configurations on page 5 and Truth Table on
page 10 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

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 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.
The CY7C1386D/CY7C1387D 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.
Accesses can

be initiated with either the processor address
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 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,
Byte write operations are qualified with the byte write enable

The CY7C1386D/CY7C1387D provides byte write capability that

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.
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.
The CY7C1386D/CY7C1387D 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.
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.
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
) 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.

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

Notes
1. X = Do not care, H = Logic HIGH, L = Logic LOW.
2. 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.
3. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
4. 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
X
the ADSP or with the assertion of
. 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
ADSC
for the remainder of the write cycle.
5. 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).

CY7C1386D
CY7C1387D
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 CY7C1387D 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 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.
The CY7C1387D 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.
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
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 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.
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.
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.
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.
TAP Instruction Set
Performing a TAP Reset
Overview
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.
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.
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 after 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 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
Document Number: 38-05545 Rev. *J
Page 12 of 34
CY7C1386D
CY7C1387D
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 can be 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 Tristate
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 #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.
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.
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.
