EDI88512CA

512Kx8 Monolithic SRAM, SMD 5962-95600

FEATURES

The EDI88512CA is a 4 megabit Monolithic CMOS

Static RAM.

■ Access Times of 15, 17, 20, 25, 35, 45, 55ns

■ Data Retention Function (LPA version)

■ TTL Compatible Inputs and Outputs

■ Fully Static, No Clocks

The 32 pin DIP pinout adheres to the JEDEC evolu-

tionary standard for the four megabit device. All 32 pin

packages are pin for pin upgrades for the single chip

enable 128K x 8, the EDI88128CS. Pins 1 and 30 be-

come the higher order addresses.

The 36 pin revolutionary pinout also adheres to the

JEDEC standard for the four megabit device. The cen-

ter pin power and ground pins help to reduce noise in

high performance systems. The 36 pin pinout also

allows the user an upgrade path to the future 2Mx8.

■ Organized as 512Kx8

■ Commercial, Industrial and Military Temperature Ranges

■ 32 lead JEDEC Approved Evolutionary Pinout

•

Ceramic Sidebrazed 600 mil DIP (Package 9)

Ceramic Sidebrazed 400 mil DIP (Package 326)

Ceramic 32 pin Flatpack (Package 344)

Ceramic Thin Flatpack (Package 321)

Ceramic SOJ (Package 140)

Low Power version with Data Retention

(EDI88512LPA) is also available for battery backed

applications. Military product is available compliant to

Appendix A of MIL-PRF-38535.

■ 36 lead JEDEC Approved Revolutionary Pinout

•

Ceramic Flatpack (Package 316)

Ceramic SOJ (Package 327)

Ceramic LCC (Package 502)

■ Single +5V (±10%) Supply Operation
