• “ZZ” Sleep Mode Option
The CY7C1380C/CY7C1382C SRAM integrates 524,288 x 36
and 1,048,576 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).
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 two or four bytes wide as
controlled by the byte write control inputs. GW when active
LOW causes all bytes to be written.
The CY7C1380C/CY7C1382C operates from a +3.3V core
power supply while all outputs may operate with either a +2.5
or +3.3V supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.

CY7C1380C
CY7C1382C
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.
Maximum access delay from the clock rise (tCO) is 3.0ns
(200-MHz device).
The CY7C1380C 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.
Three synchronous Chip Selects (CE1, CE2, CE3) and an
asynchronous Output Enable (OE) provide for easy bank
selection and output tri-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)
CE1, CE2, CE3 are all asserted active, and (3) the Write
signals (GW, BWE) are all deserted HIGH. ADSP is ignored if
CE1 is HIGH. The address presented to the address inputs (A)
is stored into the address advancement logic and the Address
Register while being presented to the memory array. 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 3.0 ns (200-MHz device) 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. Once
the SRAM is deselected at clock rise by the chip select and
either ADSP or ADSC signals, its output will tri-state immediately.
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) CE1, CE2, CE3 are all asserted active. The address
Document #: 38-05237 Rev. *D
presented to A is loaded into the address register and the
address advancement logic while being delivered to the
memory array. 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 DQs inputs is written into the corresponding address location in the memory array. If GW is HIGH,
then the Write operation is controlled by BWE and BWX
signals. The CY7C1380C provides Byte Write capability that
is described in the Write Cycle Descriptions table. Asserting
the Byte Write Enable input (BWE) with the selected Byte
Write (BWX) 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 CY7C1380C is a common I/O device, the Output
Enable (OE) must be deserted HIGH before presenting data
to the DQs inputs. Doing so will tri-state the output drivers. As
a safety precaution, DQs 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
deserted HIGH, (3) CE1, CE2, CE3 are all 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 to A is loaded into
the address register and the address advancement logic while
being delivered to the memory array. The ADV input is ignored
during this cycle. If a global Write is conducted, the data
presented to the DQs 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 CY7C1380C is a common I/O device, the Output
Enable (OE) must be deserted HIGH before presenting data
to the DQs inputs. Doing so will tri-state the output drivers. As
a safety precaution, DQs are automatically tri-stated whenever
a Write cycle is detected, regardless of the state of OE.
Burst Sequences
The CY7C1380C provides a two-bit wraparound counter, fed
by A1: A0, 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.
Page 12 of 36
CY7C1380C
CY7C1382C
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. CE1, CE2, CE3, ADSP, and ADSC must
remain inactive for the duration of tZZREC after the ZZ input
returns LOW

Notes:
3. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
4. 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.
5. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
6. CE1, CE2, and CE3 are available only in the TQFP package. BGA package has only 2 chip selects CE1 and CE2.
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

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).

CY7C1382C
IEEE 1149.1 Serial Boundary Scan (JTAG)
Test MODE SELECT (TMS)
The CY7C1380C incorporates a serial boundary scan test
access port (TAP). This port operates in accordance with IEEE
Standard 1149.1-1990 but does not 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 that 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 CY7C1380C 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
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 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 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.)
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. (See Tap Controller State Diagram.)

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.
Three-bit instructions can be serially loaded into the instruction
register. This register is loaded when it is placed between the
Page 15 of 36
CY7C1380C
CY7C1382C
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 SRAM has a 75-bit-long
register.
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.
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.
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.
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 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 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.
Identification (ID) Register
SAMPLE/PRELOAD
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.
SAMPLE/PRELOAD is a 1149.1 mandatory instruction. The
PRELOAD portion of this instruction is not implemented, so
the device TAP controller is not fully 1149.1 compliant.
TAP Instruction Set
The user must be aware that the TAP controller clock can only
operate at a frequency up to 10 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.
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.
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.
Document #: 38-05237 Rev. *D
When the SAMPLE/PRELOAD instruction is loaded into the
instruction register and the TAP controller is in the Capture-DR
state, a snapshot of data on the inputs and bidirectional balls
is captured in the boundary scan register.
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 time (tCS plus 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 CLK 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 balls.

CY7C1380C
CY7C1382C
Note that since the PRELOAD part of the command is not
implemented, putting the TAP to the Update-DR state while
performing a SAMPLE/PRELOAD instruction will have the
same effect as the Pause-DR command.
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.

Notes:
15. 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.
16. 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.
17. 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
18. This parameter is sampled and not 100% tested.
19. Timing reference level is 1.5V when VDDQ = 3.3V and is 1.25V when VDDQ = 2.5V.
20. Test conditions shown in (a) of AC Test Loads unless otherwise noted.
