EDI8F32512V
512Kx32 Static RAM CMOS, High Speed Module
FEATURES
n 512Kx32 bit CMOS Static RAM Access Times: 15, 20 and 25ns Individual Byte Selects Fully Static, No Clocks TTL Compatible I/O n High Density Package 72 Pin ZIP, No. 173 72 lead SIMM, No. 174 Common Data Inputs and Outputs n Single +3.3V (±10%) Supply Operation
DESCRIPTION
The EDI8F32512V is a high speed 16Mb Static RAM module organized as 512K words by 32 bits. This module is constructed from four 512Kx8 Static RAMs in SOJ packages on an epoxy laminate (FR4) board. 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. The EDI8F32512V is offered in 72 pin ZIP and 72 lead SIMM packages, which enable 16Mb 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 3.3V supply. Fully asynchronous circuitry requires no clocks or refreshing for operation and provides equal access and cycle times for ease of use. Pins PD0- PD3, are used to identify module memory density in applications where alternate modules can be interchanged.
* This product is subject to change without notice.
