EDI8F32259C
256Kx32 STATIC RAM CMOS, HIGH SPEED MODULE
FEATURES
DESCRIPTION
„
The EDI8F32259C is a high speed 8Mb Static RAM
module organized as 256K words by 32 bits. This module
is constructed from eight 256Kx4 Static RAMs in SOJ
packages on an epoxy laminate (FR4) board.
„
„
256Kx32 bit CMOS Static RAM
„
Access Times: 15, 20, and 25ns
„
Individual Byte Selects
„
Fully Static, No Clocks
„
TTL Compatible I/O
Four chip enables (EØ# - E3#) are used to independently
enable the four bytes. Reading or writing can be executed
on individual bytes or any combination of multiple bytes
through proper use of selects.
High Density Package with JEDEC Standard
Pinouts
„
72 Pin SIMM No. 175 (Angle)
„
72 Pin ZIP No. 176
„
72 Pin SIMM, No. 354 (Straight)
The EDI8F32259C is offered in 72 pin ZIP/SIMM package
which enables eight megabits of memory to be placed in
less than 1.3 square inches of board space.
All inputs and outputs are TTL compatible and operate from
a single 5V supply. Fully asynchronous circuitry requires
no clocks or refreshing for operation and provides equal
access and cycle times for ease of use.
Single +5V (±10%) Supply Operation
The ZIP and SIMM modules contain four PD (Presence
Detect) pins which are used to identify module memory
density in applications where alternate modules can be
interchanged.
