The CY7C1371KV33/CY7C1371KVE33/CY7C1373KV33 are
3.3 V, 512K × 36/1M × 18 synchronous flow through burst SRAM
designed specifically to support unlimited true back-to-back
read/write operations with no wait state insertion. The
CY7C1371KV33/CY7C1371KVE33/CY7C1373KV33
are
equipped with the advanced No Bus Latency (NoBL) logic
required to enable consecutive read/write operations with data
being transferred on every clock cycle. This feature dramatically
improves the throughput of data through the SRAM, especially
in systems that require frequent write-read transitions.
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. The clock input is qualified by the
clock enable (CEN) signal, which when deasserted suspends
operation and extends the previous clock cycle. Maximum
access delay from the clock rise is 6.5 ns (133 MHz device).
Write operations are controlled by the two or four byte write
select (BWX) and a write enable (WE) input. All writes are
conducted with on-chip synchronous self-timed write circuitry.
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) provide for easy bank
selection and output tristate control. To avoid bus contention, the
output drivers are synchronously tristated during the data portion
of a write sequence.

CY7C1373KV33
Functional Overview
The CY7C1371KV33/CY7C1371KVE33/CY7C1373KV33 is a
synchronous flow through burst SRAM designed specifically to
eliminate wait states during write-read transitions. All
synchronous inputs pass through input registers controlled by
the rising edge of the clock. The clock signal is qualified with the
clock enable input signal (CEN). If CEN is HIGH, the clock signal
is not recognized and all internal states are maintained. All
synchronous operations are qualified with CEN. Maximum
access delay from the clock rise (tCDV) is 6.5 ns (133 MHz
device).
Accesses can be initiated by asserting all three chip enables
(CE1, CE2, CE3) active at the rising edge of the clock. If clock
enable (CEN) is active LOW and ADV/LD is asserted LOW, the
address presented to the device is latched. The access can
either be a read or write operation, depending on the status of
the write enable (WE). BWX can be used to conduct byte write
operations.
Write operations are qualified by the write enable (WE). All writes
are simplified with on-chip synchronous self-timed write circuitry.
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) simplify depth expansion. All
operations (reads, writes, and deselects) are pipelined. ADV/LD
must be driven LOW after the device has been deselected to
load a new address for the next operation.
Single Read Accesses
A read access is initiated when these conditions are satisfied at
clock rise:
■
CEN is asserted LOW
■
CE1, CE2, and CE3 are all asserted active
■
The write enable input signal WE is deasserted HIGH
■
ADV/LD is asserted LOW.
The address presented to the address inputs is latched into the
address register and presented to the memory array and control
logic. The control logic determines that a read access is in
progress and allows the requested data to propagate to the
output buffers. The data is available within 6.5 ns (133-MHz
device) provided OE is active LOW. After the first clock of the
read access, the output buffers are controlled by OE and the
internal control logic. OE must be driven LOW in order for the
device to drive out the requested data. On the subsequent clock,
another operation (read/write/deselect) can be initiated. When
the SRAM is deselected at clock rise by one of the chip enable
signals, its output is tristated immediately.
Burst Read Accesses
The CY7C1371KV33/CY7C1371KVE33/CY7C1373KV33 has
an on-chip burst counter that allows the user the ability to supply
a single address and conduct up to four reads without
reasserting the address inputs. ADV/LD must be driven LOW to
load a new address into the SRAM, as described in the Single
Document Number: 001-97852 Rev. *F
Read Accesses section above. The sequence of the burst
counter is determined by the MODE input signal. A LOW input
on MODE selects a linear burst mode, a HIGH selects an
interleaved burst sequence. Both burst counters use A0 and A1
in the burst sequence, and wraps around when incremented
sufficiently. A HIGH input on ADV/LD increments the internal
burst counter regardless of the state of chip enable inputs or WE.
WE is latched at the beginning of a burst cycle. Therefore, the
type of access (read or write) is maintained throughout the burst
sequence.
Single Write Accesses
Write access are initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2,
and CE3 are all asserted active, and (3) the write signal WE is
asserted LOW. The address presented to the address bus is
loaded into the address register. The write signals are latched
into the control logic block. The data lines are automatically
tristated regardless of the state of the OE input signal. This
allows the external logic to present the data on DQs and DQPX.
On the next clock rise the data presented to DQs and DQPX (or
a subset for byte write operations, see truth table for details)
inputs is latched into the device and the write is complete.
Additional accesses (read/write/deselect) can be initiated on this
cycle.
The data written during the write operation is controlled by BWX
signals. The CY7C1371KV33/CY7C1371KVE33/
CY7C1373KV33 provides byte write capability that is described
in the truth table. Asserting the write enable input (WE) with the
selected byte write select input selectively writes to only 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. Byte write
capability has been included to greatly simplify read/modify/write
sequences, which can be reduced to simple byte write
operations.
Because the CY7C1371KV33/CY7C1371KVE33/
CY7C1373KV33 is a common I/O device, data must not be
driven into the device while the outputs are active. The output
enable (OE) can be deasserted HIGH before presenting data to
the DQs and DQPX inputs. Doing so tristates the output drivers.
As a safety precaution, DQs and DQPX are automatically
tristated during the data portion of a write cycle, regardless of the
state of OE.
Burst Write Accesses
The CY7C1371KV33/CY7C1371KVE33/CY7C1373KV33 has
an on-chip burst counter that allows the user the ability to supply
a single address and conduct up to four write operations without
reasserting the address inputs. ADV/LD must be driven LOW to
load the initial address, as described in the Single Write
Accesses section above. When ADV/LD is driven HIGH on the
subsequent clock rise, the chip enables (CE1, CE2, and CE3)
and WE inputs are ignored and the burst counter is incremented.
The correct BWX inputs must be driven in each cycle of the burst
write, to write the correct bytes of data.

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,
and CE3, must remain inactive for the duration of tZZREC after the
ZZ input returns LOW.

Notes
1. X = “Don't Care.” H = Logic HIGH, L = Logic LOW. BWX = 0 signifies at least one byte write select is active, BWX = valid signifies that the desired byte write selects
are asserted, see truth table for details.
2. Write is defined by BWX, and WE. See Truth Table for read/write.
3. When a write cycle is detected, all I/Os are tristated, even during byte writes.
4. The DQs and DQPX pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
5. CEN = H, inserts wait states.
6. Device powers up deselected and the I/Os in a tristate condition, regardless of OE.
7. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle DQs and DQPX = tristate when OE is inactive
or when the device is deselected, and DQs and DQPX = data when OE is active.

Notes
13. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V.
14. Test conditions shown in (a) of Figure 3 on page 15 unless otherwise noted.
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 Figure 3 on page 15. Transition is measured ±200 mV from steady-state voltage.
17. 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.
18. This parameter is sampled and not 100% tested.
