Functional Description
[1]
The CY7C1352G is a 3.3V, 256K x 18 synchronous-pipelined
Burst SRAM designed specifically to support unlimited true
back-to-back Read/Write operations without the insertion of
wait states. The CY7C1352G is equipped with the advanced
No Bus Latency (NoBL) logic required to enable consec-
utive Read/Write operations with data being transferred on
every clock cycle. This feature dramatically improves the
throughput of 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. All data outputs pass through
output 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 2.6 ns (250-MHz device).
Write operations are controlled by the two Byte Write Select
(BW
[A:B]
) 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.
