Functional Description
The CY7C1381KV33/CY7C1381KVE33/CY7C1383KV33/
CY7C1383KVE33 are a 3.3 V, 512K × 36 and 1M × 18
synchronous flow through SRAMs, designed to interface with
high speed microprocessors with minimum glue logic. Maximum
access delay from clock rise is 6.5 ns (133 MHz version). A 2-bit
on-chip counter captures the first address in a burst and
increments the address automatically for the rest of the burst
access. All synchronous inputs are gated by registers controlled
by a positive edge triggered clock input (CLK). The synchronous
inputs include all addresses, all data inputs, address pipelining
chip enable (CE1), depth-expansion chip enables (CE2 and
CE3), burst control inputs (ADSC, ADSP, and ADV), write
enables (BWx, and BWE), and global write (GW). Asynchronous
inputs include the output enable (OE) and the ZZ pin.
The CY7C1381KV33/CY7C1381KVE33/CY7C1383KV33/
CY7C1383KVE33 allows interleaved or linear burst sequences,
selected by the MODE input pin. A HIGH selects an interleaved
burst sequence, while a LOW selects a linear burst sequence.
Burst accesses can be initiated with the processor address
strobe (ADSP) or the cache controller address strobe (ADSC)
inputs. Address advancement is controlled by the address
advancement (ADV) input.
Addresses and chip enables are registered at rising edge of
clock when address strobe processor (ADSP) or address strobe
controller (ADSC) are active. Subsequent burst addresses can
be internally generated as controlled by the advance pin (ADV).
CY7C1381KV33/CY7C1381KVE33/CY7C1383KV33/
CY7C1383KVE33 operates from a +3.3 V core power supply
while all outputs operate with a +2.5 V or +3.3 V supply. All inputs
and outputs are JEDEC-standard and JESD8-5-compatible.
