spectively. They are designed specifically to support unlimited
true back-to-back Read/Write operations without the insertion
of wait states. The CY7C1354V25/CY7C1356V25 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 im-
proves the throughput of data through the SRAM, especially in
systems that require frequent Write/Read transitions. The
CY7C1354V25/CY7C1356V25 is pin compatible and function-
ally 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 previ-
ous clock cycle. Maximum access delay from the clock rise is
3.2 ns (200-MHz device).
Write operations are controlled by the Byte Write Selects
(BWS
CY7C1356V25) and a Write Enable (WE) input. All writes are
conducted with on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE
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.
