Functional Description
The CY7C1354C/CY7C1356C[1] are 3.3 V,
256K × 36/512K × 18 synchronous pipelined burst SRAMs with
No Bus Latency™ (NoBL™) logic, respectively. They are
designed to support unlimited true back-to-back read/write
operations with no wait states. The CY7C1354C/CY7C1356C
are equipped with the advanced (NoBL) logic required to enable
consecutive read/write operations with data being transferred on
every clock cycle. This feature greatly improves the throughput
of data in systems that require frequent write/read transitions.
The CY7C1354C/CY7C1356C are pin compatible and
functionally equivalent to ZBT devices.
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.
Write operations are controlled by the byte write selects
(BWa–BWd for CY7C1354C and BWa–BWb for CY7C1356C)
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.
