EDI88257CA

HI-RELIABILITY PRODUCT

256Kx8 Monolithic SRAM

FEATURES

The EDI88257CA is a 2 Megabit 256Kx8 bit Monolithic CMOS

Static RAM.

■ Access Times of 20, 25, 35, 45, 55ns

■ Data Retention Function (LPA Versions)

■ TTL Compatible Inputs and Outputs

■ Fully Static, No Clocks

The 32 pin DIP pinout adheres to the JEDEC evolutionary standard

for the two megabit device. The device is upgradeable to the

512Kx8 SRAM, the EDI88512CA. Pin 1 becomes the higher order

address.

■ Organized as 256Kx8

A Low Power version, EDI88257LPA, offers a data retention

function for battery back-up opperation. Military product is avail-

able compliant to Appendix A of MIL-PRF-38535.

■ Commercial, Industrial and Military Temperature Ranges

■ JEDEC Approved Evolutionary Pinout

• 32 pin Ceramic DIP, 0.6 mils wide (Package 9)

■ Single +5V (±10%) Supply Operation
