EDI88128C
128Kx8 MONOLITHIC SRAM, SMD 5962-89598
FEATURES
Access Times of 70, 85, 100ns
Available with Single Chip Selects (EDI88128) or
Dual Chip Selects (EDI88130)
2V Data Retention (LP Versions)
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.
CS# and OE# Functions for Bus Control
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
Organized as 128Kx8
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.
Industrial, Military and Commercial Temperature

Thru-hole and Surface Mount Packages JEDEC
Pinout
• 32 pin Ceramic DIP, 0.6 mils wide (Package 9)
• 32 lead Ceramic SOJ (Package 140)
Single +5V (±10%) Supply Operation
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.
