FEATURES
The EDI88128C is a high speed, high performance, Mono-
lithic CMOS Static RAM organized as 128Kx8.
The device is also available as EDI88130C with an additional
chip select line (CS2) which will automatically power down
the device when proper logic levels are applied.
The second chip select line (CS2) can be used to provide
system memory security during power down in non-battery
backed up systems and simplifiy decoding schemes in memory
banking where large multiple pages of memory are required.
The EDI88128C and the EDI88130C have eight bi-directional
input-output lines to provide simultaneous access to all
bits in a word. An automatic power down feature permits
the on-chip circuitry to enter a very low standby mode and
be brought back into operation at a speed equal to the
address access time.
Low power versions, EDI88128LP and EDI88130LP, offer a
2V data retention function for battery back-up opperation.
Military product is available compliant to Appendix A of
MIL-PRF-38535.
