DESCRIPTION
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.
The EDI8L32128C, allows 4 megabits of memory to
be placed in less than 0.990 square inches of board
space; a savings of 0.885 square inches over four
standard 128Kx8 components.
NOTE: Solder Reflow temperature should not exceed 230°C
