Functional Description
The CY7C1470BV25, CY7C1472BV25, and CY7C1474BV25
are 2.5V, 2M x 36/4M x 18/1M x 72 synchronous pipelined burst
SRAMs with No Bus Latency (NoBL
) logic, respectively.
They are designed to support unlimited true back-to-back read
or write operations with no wait states. The CY7C1470BV25,
CY7C1472BV25, and CY7C1474BV25 are equipped with the
advanced (NoBL) logic required to enable consecutive read or
write operations with data being transferred on every clock cycle.
This feature dramatically improves the throughput of data in
systems that require frequent read or write transitions. The
CY7C1470BV25, CY7C1472BV25, and CY7C1474BV25 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
CY7C1470BV25,
BWa–BWb
for
CY7C1472BV25, and BWa–BWh for CY7C1474BV25) 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. To avoid bus contention,
the output drivers are synchronously tri-stated during the data
portion of a write sequence.
