GENERAL DESCRIPTION

The Austin Semiconductor, Inc. Zero Bus Latency SRAM family employs high-speed, low-power CMOS designs using an advanced CMOS process.

FEATURES

? High frequency and 100% bus utilization

? Fast cycle times: 11ns & 12ns

? Single +3.3V +5% power supply (VDD)

? Advanced control logic for minimum control signal interface

? Individual BYTE WRITE controls may be tied LOW

? Single R/W (READ/WRITE) control pin

? CKE pin to enable clock and suspend operations

? Three chip enables for simple depth expansion

? Clock-controlled and registered addresses, data I/Os and control signals

? Internally self-timed, fully coherent WRITE

? Internally self-timed, registered outputs to eliminate the need to control OE

? SNOOZE MODE for reduced-power standby

? Common data inputs and data outputs

? Linear or Interleaved Burst Modes

? Burst feature (optional)

? Pin/function compatibility with 2Mb, 8Mb, and 16Mb ZBL SRAM

? Automatic power-down
