Functional Description
The CY7C1370D and CY7C1372D are 3.3V, 512K x 36 and
1 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 operations
with no wait states. The CY7C1370D and CY7C1372D are
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 CY7C1370D and CY7C1372D 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

for CY7C1370D and BW

for CY7C1372D)
and a Write Enable (WE) input. All writes are conducted with
on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE
1
, CE
2
, CE

) and an
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.
