Functional Description
[1]
The CY7C1334H is a 3.3V/2.5V, 64K x 32
synchronous-pipelined Burst SRAM designed specifically to
support unlimited true back-to-back Read/Write operations
without the insertion of wait states. The CY7C1334H is
equipped with the advanced No Bus Latency鈩?(NoBL鈩? logic
required to enable consecutive Read/Write operations with
data being transferred on every clock cycle. This feature
dramatically improves the throughput of the SRAM, especially
in systems that require frequent Write/Read transitions.
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. Maximum access delay from the clock
rise is 3.5 ns (166-MHz device)
Write operations are controlled by the four Byte Write Select
(BW
[A:D]
) 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
3
) and an
asynchronous Output Enable (OE) provide for easy bank
selection and output tri-state control. In order to avoid bus
contention, the output drivers are synchronously tri-stated
during the data portion of a write sequence.
