The EDI88512CA is a 4 megabit Monolithic CMOS

Static RAM.

The 32 pin DIP pinout adheres to the JEDEC evolutionary

standard for the four megabit device. All 32 pin packages

are pin for pin upgrades for the single chip enable 128K

x 8, the EDI88128CS. Pins 1 and 30 become the higher

order addresses.

The 36 pin revolutionary pinout also adheres to the

JEDEC standard for the four megabit device. The center

pin power and ground pins help to reduce noise in high

performance systems. The 36 pin pinout also allows the

user an upgrade path to the future 2Mx8.

A Low Power version with Data Retention (EDI88512LPA)

is also available for battery backed applications. Military

product is available compliant to Appendix A of MIL-

PRF-38535.
