Functional Description
The CY7C1470BV33, CY7C1472BV33, and CY7C1474BV33
are 3.3 V, 2 M × 36/4 M × 18/1 M × 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
CY7C1470BV33, CY7C1472BV33, and CY7C1474BV33 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 CY7C1470BV33, CY7C1472BV33, and
CY7C1474BV33 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 CY7C1470BV33, BWa–BWb for
CY7C1472BV33, and BWa–BWh for CY7C1474BV33) 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.
