PIN CONFIGURATION
The EDI88128C is a high speed, high performance, Monolithic
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 in-
put-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 prod-
uct is available compliant to Appendix A of MIL-PRF-38535.
