EDI88128CS
128Kx8 Monolithic SRAM, SMD 5962-89598
FEATURES
Access Times of 15*, 17, 20, 25, 35, 45, 55ns
CS# and OE# Functions for Bus Control
2V Data Retention (EDI88128LPS)
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
• 32 pad Ceramic LCC (Package 141)
• 32 lead Ceramic Flatpack (Package 142)
Single +5V (±10%) Supply OperationThe
EDI88128CS is a high speed, high performance,
128Kx8 megabit density Monolithic CMOS Static
RAM.
Organized as 128Kx8
Commercial, Industrial and Military Temperature
Ranges
Thru-hole and Surface Mount Packages JEDEC
Pinout
• 32 pin Ceramic DIP, 400 mil (Package 102)
• 32 pin Ceramic DIP, 600 mil (Package 9)
The device has 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.
ALow Power version with 2V Data Retention (EDI88128LPS)
is also available for battery back-up opperation. Military
product is available compliant to MIL-PRF-38535.
• 32 lead Ceramic ZIP (Package 100)
• 32 lead Ceramic SOJ (Package 140)
* 15ns access time is advanced information, contact factory for availability.
This product is subject to change without notice.
