Functional Description
The CY7C1441AV33 are 3.3 V, 1 M × 36 Synchronous
Flow-through SRAMs, respectively 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 (CE
1
), depth-expansion Chip
Enables (CE
2
and CE
3
), Burst Control inputs (ADSC, ADSP, and
ADV), Write Enables (BW
x
, and BWE), and Global Write (GW).
Asynchronous inputs include the Output Enable (OE) and the ZZ
pin.
The CY7C1441AV33 allows either 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 either 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).
The CY7C1441AV33 operates from a +3.3 V core power supply
while all outputs may operate with either a +2.5 or +3.3 V supply.
