GENERAL DESCRIPTION
The W25Z040A is a high-speed, low-power, Zero-Wait-State (ZWS) Synchronous Pipelined CMOS
Static RAM organized as 131,072
×
36 bits. A built-in two-bit burst address counter supports both
Linear and Interleaved burst mode. The mode to be executed is controlled by the
LBO
pin. A snooze
mode can reduce the power dissipation.
The ZWS SRAM is optimized for 100 percent bus utilization by eliminating wait states when
transitioning from read to write, or vice versa. All addresses, data inputs, clock enable (
CLKE
), write
enable (
WE
), byte-write enables (
BW
[4:1]) and chip enables (
CE1
, CE2 and
CE3
for easy depth
expansion) are synchronously sampled with by a positive-edge-triggered clock (CLK). Asynchronous
inputs include the output enable (OE), clock (CLK) and snooze (ZZ).
To provide 100 percent use of the data bus, the pipelined ZWS SRAM uses the two-stage write
address registers. For example, when the address and control signals are applied to the SRAM in
clock cycle one, the data associated with the address occurs two cycles later, or the clock cycle three.
The W25Z040A operates on a single 3.3V power supply, with all inputs and outputs compatible with
the LVTTL interface. Based on the bus efficiency, the device is ideal for high bandwidth application
systems.
