Functional Description
The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 are
2.5V, 1-Mbit x 36/2-Mbit 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
CY7C1460AV25/CY7C1462AV25/CY7C1464AV25
equipped with the advanced (NoBL) logic required to enable
consecutive Read/Write operations with data being trans-
ferred on every clock cycle. This feature dramatically improves
the throughput of data in systems that require frequent
Write/Read transitions. The CY7C1460AV25/ CY7C1462AV25/
CY7C1464AV25 are pin-compatible and functionally equiv-
alent 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
BW
CY7C1462AV25) 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.
