EDI88128CS

White Electronic Designs 128Kx8 Monolithic SRAM, SMD 5962-89598 FEATURES Access Times of 15*, 17, 20, 25, 35, 45, 55ns CS# and OE# Functions for Bus Control 2V Data Retention (EDI88128LPS) TTL Compatible Inputs and Outputs Fully Static, No Clocks Organized as 128Kx8 Commercial, Industrial and Military Temperature Ranges Thru-hole and Surface Mount Packages JEDEC Pinout • 32 pin Ceramic DIP, 400 mil (Package 102) • 32 pin Ceramic DIP, 600 mil (Package 9) • 32 lead Ceramic ZIP (Package 100) • 32 lead Ceramic SOJ (Package 140) EDI88128CS • 32 pad Ceramic LCC (Package 141) • 32 lead Ceramic Flatpack (Package 142) Single +5V (±10%) Supply OperationThe EDI88128CS is a high speed, high performance, 128Kx8 megabit density Monolithic CMOS Static RAM. The device has eight bi-directional input-output lines to provide simultaneous access to all bits in a word. An automatic power down feature permits the on-chip circuitry to enter a very low standby mode and be brought back into operation at a speed equal to the address access time. A Low Power version with 2V Data Retention (EDI88128LPS) is also available for battery back-up opperation. Military product is available compliant to MIL-PRF-38535. * 15ns access time is advanced information, contact factory for availability. This product is subject to change without notice.
