WEDC EDI88128LPXCM 128kx8 monolithic sram, smd 5962-89598 Datasheet

White Electronic Designs
EDI88128C
128Kx8 MONOLITHIC SRAM, SMD 5962-89598
The EDI88128C is a high speed, high performance,
Monolithic CMOS Static RAM organized as 128Kx8.
FEATURES
Access Times of 70, 85, 100ns
Available with Single Chip Selects (EDI88128) or
Dual Chip Selects (EDI88130)
2V Data Retention (LP Versions)
CS# and OE# Functions for Bus Control
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
Organized as 128Kx8
Industrial, Military and Commercial Temperature
Ranges
Thru-hole and Surface Mount Packages JEDEC
Pinout
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 bidirectional 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.
• 32 pin Ceramic DIP, 0.6 mils wide (Package 9)
• 32 lead Ceramic SOJ (Package 140)
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.

NOTE:
Stress greater than those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions greater than those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
