White Electronic Designs EDI8F32128C 128KX32 STATIC RAM CMOS, HIGH SPEED MODULE FEATURES 128Kx32 bit CMOS Static Random Access Memory www.DataSheet4U.com DESCRIPTION The EDI8F32128C is a high speed 4Mb Static RAM module organized as 128K words by 32 bits. This module is constructed from four 128Kx8 Static RAMs in SOJ packages on an epoxy laminate (FR4) board. Four chip enables (E0# - 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 EDI8F32128C is offered in 64 pin ZIP/SIMM package which enables eight megabits of memory to be placed in less than 1.4 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 two pins, PD1 and PD2, which are used to identify module memory density in applications where alternate modules can be interchanged. Access Times: 15, 20, and 25ns Individual Byte Selects Fully Static, No Clocks TTL Compatible I/O Single +5V (±10%) Supply Operation High Density Package with JEDEC Standard Pinouts 64 Pin ZIP, No. 85 Height: 13.97 (0.550") 64 Lead SIMM, No. 333 Height: 15.62 (0.615") Common Data Inputs and Outputs FIG. 1 – PIN CONFIGURATIONS AND BLOCK DIAGRAM PD0 DQ0 DQ1 DQ2 DQ3 VCC A7 A8 A9 DQ4 DQ5 DQ6 DQ7...
