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.
