CYPRESS CY7C1386D

CY7C1386D, CY7C1386F
CY7C1387D, CY7C1387F
18-Mbit (512K x 36/1 Mbit x 18) Pipelined DCD Sync SRAM
Functional Description [1]
Features
• Supports bus operation up to 250 MHz
The
CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
SRAM integrates 512K x 36/1M x 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.
• Available speed grades are 250, 200, and 167 MHz
• Registered inputs and outputs for pipelined operation
• Optimal for performance (double-cycle deselect)
• Depth expansion without wait state
• 3.3V core power supply (VDD)
• 2.5V or 3.3V IO power supply (VDDQ)
• Fast clock-to-output times
— 2.6 ns (for 250 MHz device)
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).
• Provides high-performance 3-1-1-1 access rate
• User selectable burst counter supporting
interleaved or linear burst sequences
Intel®
Pentium®
• Separate processor and controller address strobes
• Synchronous self timed writes
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 3 and Truth Table
[4, 5, 6, 7, 8] on page 9 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.
• Asynchronous output enable
• CY7C1386D/CY7C1387D available in JEDEC-standard
Pb-free 100-pin TQFP, Pb-free and non Pb-free 165-ball
FBGA package. CY7C1386F/CY7C1387F available in
Pb-free and non Pb-free 119-ball BGA package
• IEEE 1149.1 JTAG-Compatible Boundary Scan
• ZZ sleep mode option
The
CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
operates from a +3.3V core power supply while all outputs
operate with a +3.3V or +2.5V supply. All inputs and outputs
are JEDEC-standard and JESD8-5-compatible.

IO
Description
A0, A1, A
InputSynchronous
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 [2]
are sampled active. A1: A0 are fed to the two-bit counter.
BWA, BWB
BWC, BWD
InputSynchronous
Byte write select inputs, active LOW. Qualified with BWE to conduct byte writes
to the SRAM. Sampled on the rising edge of CLK.
GW
InputSynchronous
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
InputSynchronous
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
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
InputSynchronous
Chip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in
conjunction with CE2 and CE3 [2] 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 [2]
InputSynchronous
Chip enable 2 input, active HIGH. Sampled on the rising edge of CLK. Used in
conjunction with CE1 and CE3[2] to select or deselect the device. CE2 is sampled
only when a new external address is loaded.
CE3 [2]
InputSynchronous
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 [2] is assumed active throughout this document for
BGA. CE3 is sampled only when a new external address is loaded.
OE
InputAsynchronous
Output enable, asynchronous input, active LOW. Controls the direction of the
IO pins. When LOW, the IO pins behave as outputs. When deasserted HIGH, DQ
pins are tri-stated, and act as input data pins. OE is masked during the first clock of
a read cycle when emerging from a deselected state.
ADV
InputSynchronous
Advance input signal, sampled on the rising edge of CLK, active LOW. When
asserted, it automatically increments the address in a burst cycle.
ADSP
InputSynchronous
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
InputSynchronous
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
InputAsynchronous
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
IOSynchronous
Bidirectional data IO 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 tri-state condition.
VDD
Power Supply
Power supply inputs to the core of the device.

Functional Overview
Single Read Accesses
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.
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 tri-stated 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
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.

is HIGH.

The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a
double cycle deselect part. Once the SRAM is deselected at
clock rise by the chip select and either ADSP or ADSC signals,
its output will tri-state immediately after the next clock rise.
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, then 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, will selectively write
to only the desired bytes. Bytes not selected during a byte
write operation will remain unaltered. A synchronous self
timed write mechanism has been provided to simplify the write
operations.
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a
common IO device, the output enable (OE) must be
deasserted HIGH before presenting data to the DQ inputs.
Doing so will tri-state the output drivers. As a safety
precaution, DQ are automatically tri-stated 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 will remain 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 will automatically increment
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
4. X = Don't Care, H = Logic HIGH, L = Logic LOW.
5. 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.
6. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
7. 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.
8. 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).

IEEE 1149.1 Serial Boundary Scan (JTAG)
Test Data-In (TDI)
The
CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
contains a TAP controller, instruction register, boundary scan
register, bypass register, and ID register.
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. (See TAP Controller Block
Diagram).
Disabling the JTAG Feature
Test Data-Out (TDO)
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 will
come up in a reset state which will not interfere with the
operation of the device.
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. (See TAP Controller State Diagram).
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 3.3V or 2.5V IO logic levels.

The 0 or 1 next to each state represents the value of TMS at
the rising edge of TCK.
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.
Document Number: 38-05545 Rev. *E
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. 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 15.
TAP Instruction Set
Overview
Eight different instructions are possible with the three bit
instruction register. All combinations are listed in Identification
Codes on page 15. 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 once 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
Document Number: 38-05545 Rev. *E
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 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.
Once 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 Tri-State
IEEE Standard 1149.1 mandates that the TAP controller be
able to put the output bus into a tri-state mode.
The boundary scan register has a special bit located at bit #85
(for 119-BGA package) or bit #89 (for 165-FBGA package).
When this scan cell, called the “extest output bus tri-state,” is
latched into the preload register during the Update-DR state in

preset HIGH to enable the output when the device is powered
up, and also when the TAP controller is in the Test-Logic-Reset

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 will latch into the preload

20. Timing reference level is 1.5V when VDDQ = 3.3V and is 1.25V when VDDQ = 2.5V.
21. Test conditions shown in (a) of AC Test Loads 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 (b) of AC Test Loads. 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.
