EDI88257C

HI-RELIABILITY PRODUCT

256Kx8 Monolithic SRAM

FEATURES

The EDI88257C is a 2 Megabit 256Kx8 bit Monolithic CMOS Static

RAM.

■ 256Kx8 CMOS Static

■ Random Access Memory

• Access Times of 70, 85, 100ns

• Data Retention Function (LP Versions)

• TTL Compatible Inputs and Outputs

• Fully Static, No Clocks

The 32 pin DIP pinout adheres to the JEDEC standard for the two

megabit device, and is a pin replacement for the 256Kx8 module,

EDI88257C. The device is upgradeable to the 512Kx8 SRAM, the

EDI88512C. Pin 1 becomes the higher order address.

A Low Power version, EDI88257LP, offers a data retention func-

tion for battery back-up opperation. Military product is available

compliant to Appendix A of MIL-PRF-38535.

■ JEDEC Approved Pinout

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

■ Single +5V (±10%) Supply Operation
