Functional Description
The CY7C1441AV33/CY7C1443AV33/CY7C1447AV33
[1]
are
3.3V, 1M x 36/2M x 18/512K x 72 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/CY7C1443AV33/CY7C1447AV33 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/CY7C1443AV33/CY7C1447AV33
operates from a +3.3V core power supply while all outputs may
operate with either a +2.5 or +3.3V supply. All inputs and outputs
are JEDEC-standard JESD8-5-compatible.
