Functional Description
The CY7C1354BV25 and CY7C1356BV25 are 2.5V, 256K x
36 and 512K x 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 CY7C1354BV25 and
CY7C1356BV25 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 CY7C1354BV25
and CY7C1356BV25 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
(BW
CY7C1356BV25) 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
selection 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.
