| White Electronic Designs EDI8F32259C 256Kx32 STATIC RAM CMOS, HIGH SPEED MODULE FEATURES 256Kx32 bit CMOS Static RAM Access Times: 15, 20, and 25ns Individual Byte Selects Fully Static, No Clocks TTL Compatible I/O High Density Package with JEDEC Standard Pinouts 72 Pin SIMM No. 175 (Angle) 72 Pin ZIP No. 176 72 Pin SIMM, No. 354 (Straight) Single +5V (10%) Supply Operation 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. Four chip enables (EO# - 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. 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. 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.
