Functional Description
The CY7C1354CV25/CY7C1356CV25[1] are 2.5 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
CY7C1354CV25/CY7C1356CV25 are equipped with the
advanced (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
in systems that require frequent write/read transitions. The
CY7C1354CV25/CY7C1356CV25 are pin-compatible with 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 CY7C1354CV25 and BWa–BWb for
CY7C1356CV25) 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 tri-state control. In order to avoid bus
contention, the output drivers are synchronously tri-stated during
the data portion of a write sequence.
