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.
Organized as 512Kx8
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.
