256Kx16 MONOLITHIC SRAM, SMD 5962-96795
FEATURES
256Kx16 bit CMOS Static
Random Access Memory
• Access Times of 17, 20, 25, 35ns
• Data Retention Function (LPA version)
• TTL Compatible Inputs and Outputs
• Fully Static, No Clocks
44 lead JEDEC Approved Revolutionary Pinout
• Ceramic SOJ (Package 322)
• Ceramic Flatpack (Package 323)
Single +5V (±10%) Supply Operation
The EDI816256CA is a 4 megabit Monolithic CMOS Static
RAM.
The EDI816256CA uses 16 common input and output
lines and has an output enable pin which operates faster
than address access time at read cycle. The device allows
upper and lower byte access by use of the data byte control
pins (LB#, UB#).
The devices are available in a fully hermetic 44 lead
ceramic SOJ and a 44 lead Ceramic Flatpack. The Ceramic
SOJ is pin for pin compatible with the commercially
available plastic SOJ. This allows the user the luxury of
designing a board that can be used for both the commercial
and military market.
A Low Power version with Data Retention (EDI816256LPA)
is also available for battery backed applications. Military
product is available compliant to Appendix A of MIL-PRF-
38535.
