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 230C
NOTE: Pin 2 & 67 on the 64Kx32 (EDI8L3265C) and the 256Kx32 (EDI8L32256C) are word select pins.

ABSOLUTE MAXIMUM RATINGS*
RECOMMENDED DC OPERATING CONDITIONS
*Stress greater than those listed under "Absolute Maximum Ratings"
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
