Logic Block Diagram
The CY7C1350B is a 3.3V, 128K by 36 synchronous-pipelined
Burst SRAM designed specifically to support unlimited true
back-to-back Read/Write operations without the insertion of
wait states. The CY7C1350B is equipped with the advanced
No Bus Latency
(NoBL
) logic required to enable consec-
utive Read/Write operations with data being transferred on ev-
ery clock cycle. This feature dramatically improves the
throughput of the SRAM, especially in systems that require
frequent Write/Read transitions. The CY7C1350B is pin/func-
tionally
compatible
to
ZBT
MT55L128L36P, and MCM63Z736.
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 previ-
ous clock cycle. Maximum access delay from the clock rise is
3.5 ns (166-MHz device).
Write operations are controlled by the four Byte Write Select
(BWS
[3:0]
) and a Write Enable (WE) input. All writes are con-
ducted 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 se-
lection and output three-state control. In order to avoid bus
contention, the output drivers are synchronously three-stated
during the data portion of a write sequence.
