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.
