EDI8F8512C White Electronic Designs 512Kx8 STATIC RAM CMOS, MODULE FEATURES DESCRIPTION 512Kx8 bit CMOS Static The EDI8F8512C is a 4096K bit CMOS Static RAM based on four 128Kx8 or 256Kx4 (high speed) Static RAMs mounted on a multilayered epoxy laminate (FR4) substrate. Random Access Memory • Access Times 20 through 100ns Functional equivalence to the monolithic four megabit Static RAM is achieved by utilization of an on-board decoder that interprets the higher order address(es) to select one of the128Kx8 or 256Kx4 Static RAMs. • Data Retention Function (EDI8F8512LP) • TTL Compatible Inputs and Outputs • Fully Static, No Clocks The 32 pin DIP pinout adheres to the JEDEC standard for the four megabit device, to ensure compatibility with future monolithics. High Density Packaging • 36 Pin SIP, No. 63 A low power version with data retention (EDI8F8512LP) is also available. • 32 Pin DIP, JEDEC Pinout, No. 91 (55-100ns) • 32 Pin DIP, JEDEC Pinout, No. 183 (20-35ns) All inputs and outputs are TTL compatible and operate from a single 5V supply. Fully asynchronous, the EDI8F8512C requires no clocks or refreshing for operation. Single +5V (±10%) Supply Operation *This product is subject to change without notice.
