Burst Capability—linear or interleaved burst order
Low standby power
The CY7C1355C/CY7C1357C is a 3.3V, 256K x 36/ 512K x 18
Synchronous Flow-through Burst SRAM designed specifically
to support unlimited true back-to-back Read/Write operations
without the insertion of wait states. The CY7C1355C/
CY7C1357C is 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 (BW
X
) and a Write Enable (WE) input. All writes are
conducted with on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE
1
, CE
2
, CE
3
) and an
asynchronous Output Enable (OE) provide for easy bank
selection and output tri-state control. In order to avoid bus
contention, the output drivers are synchronously tri-stated
during the data portion of a write sequence.
