Sync SRAM
Functional Description[1]
Features
• Supports bus operation up to 225 MHz
• Available speed grades are 225, 200 and 166 MHz
• Registered inputs and outputs for pipelined operation
•Optimal for performance (Double-Cycle deselect)
—Depth expansion without wait state
•3.3V –5% and +10% core power supply (VDD)
• 2.5V / 3.3V I/O operation
• Fast clock-to-output times
— 2.8 ns (for 225-MHz device)
The CY7C1366C/CY7C1367C SRAM integrates 262,144 x 36
and 524,288 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.
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).
— 3.0 ns (for 200-MHz device)
— 3.5 ns (for 166-MHz device)
• Provide high-performance 3-1-1-1 access rate
• User-selectable burst counter supporting Intel
Pentium interleaved or linear burst sequences
• Separate processor and controller address strobes
• Synchronous self-timed writes
• Asynchronous output enable
• Available in Lead-Free 100 TQFP,119 BGA and 165 fBGA
packages
• IEEE 1149.1 JTAG-Compatible Boundary Scan
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 Descriptions and Truth Table 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 CY7C1366C/CY7C1367C operates from a +3.3V core
power supply while all outputs operate with a +3.3V or a +2.5V
supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.

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 CY7C1366C/CY7C1367C supports secondary cache in
systems utilizing 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 utilize 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[2] and an
asynchronous Output Enable (OE) provide for easy bank
selection and output three-state 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 three-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 CY7C1366C/CY7C1367C 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 three-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 CY7C1366C/CY7C1367C 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.
Because the CY7C1366C/CY7C1367C is a common I/O
device, the Output Enable (OE) must be deasserted HIGH
before presenting data to the DQ inputs. Doing so will
three-state the output drivers. As a safety precaution, DQ are
automatically three-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.
Because the CY7C1366C/CY7C1367C is a common I/O
device, the Output Enable (OE) must be deasserted HIGH
before presenting data to the DQX inputs. Doing so will
three-state the output drivers. As a safety precaution, DQX are

automatically three-stated whenever a write cycle is detected,
regardless of the state of OE.
Burst Sequences
The CY7C1366C/CY7C1367C 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. Both read and write burst
operations are supported.
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.

CY7C1367C
PRELIMINARY
IEEE 1149.1 Serial Boundary Scan (JTAG)
Test MODE SELECT (TMS)
The CY7C1366C/CY7C1367C 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
doesn’t 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 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 3.3V or 2.5V I/O logic levels.
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 CY7C1366C/CY7C1367C 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. For
information on loading the instruction register, see Figure .
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 should 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.)

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.
The 0/1 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.
Document #: 38-05542 Rev. *A
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.
Page 9 of 27
PRELIMINARY
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
CY7C1366C
CY7C1367C
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.
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.
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.
Boundary Scan Register
IDCODE
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 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 table.
TAP Instruction Set
Overview
Eight different instructions are possible with the three-bit
instruction register. All combinations are listed in the
Instruction Codes table. Three of these instructions are listed
as RESERVED and should not be used. The other five instructions are described in detail below.
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.
Document #: 38-05542 Rev. *A
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.
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 set-up 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.

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.
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.
Reserved
These instructions are not implemented but are reserved for
future use. Do not use these instructions.
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

Notes:
10. 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.
11. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
12. 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
13. This parameter is sampled and not 100% tested.
14. Timing reference level is 1.5V when VDDQ = 3.3V and is 1.25V when VDDQ = 2.5V.
15. Test conditions shown in (a) of AC Test Loads unless otherwise noted.
