GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8SLC128K32 is a high speed,
4MB CMOS SRAM multichip module (MCM) designed for full
temperature range, 3.3V power supply, military, space, or high
reliability mass memory and fast cache applications.
The device input and output TTL compatible. Writing is
executed when the write enable (WE\) and chip enable (CS\) inputs are
low. Reading is accomplished when WE\ is high and CS\ and output
enable (OE\) are both low. Access time grades of 10ns, 12ns, 15ns,
17ns, 20ns and 25ns maximum are standard.
The products are designed for operation over the temperature
range of -55°C to +125°C and screened under the full military
environment.
