DESCRIPTION
NOTE: Solder Reflow temperature should not exceed 230°C
The EDI8L32128C is a high speed, high performance,
four megabit density Static RAM organized as a 128Kx32
bit array.
Four Chip Enables, Write Control, and Output Enable
provide the user with a flexible memory solution. The user
may independently enable each of the four bytes, and,
with minimal additional peripheral logic, the unit may be
configured as a 256Kx16 or 512Kx8 array.
Fully asynchronous circuitry is used, requiring no clocks or
refreshing for operation and providing equal access and
cycle times for ease of use.
placed in less than 0.990 square inches of board space; a
savings of 0.885 square inches over four standard 128Kx8
components.
The EDI8L32128C, allows 4 megabits of memory to be
