Single +5V (±10%) Supply OperationThe EDI88130CS is
a high speed, high performance, 128Kx8 bits monolithic
Static RAM.
An additional chip enable line provides system memory security
during power down in non-battery backed up systems and memory
banking in high speed battery backed systems where large multiple
pages of memory are required.
The EDI88130CS has eight bi-directional input-output lines to provide
simultaneous access to all bits in a word.
A low power version, EDI88130LPS, offers a 2V data retention
function for battery back-up applications.
Military product is available compliant to MIL-PRF-38535.
* 15ns access time is advanced information, contact factory for availability.
This product is subject to change without notice.
