ETC EDI88512C/LP-C

EDI88512C
HI-RELIABILITY PRODUCT
512Kx8 Monolithic SRAM CMOS
FEATURES
■ 512Kx8 bit CMOS Static
The EDI88512C is a 4 megabit Monolithic CMOS Static RAM.
■ Random Access Memory
• Access Times of 70, 85, 100ns
• Data Retention Function (LP version)
• TTL Compatible Inputs and Outputs
• Fully Static, No Clocks
The 32 pin DIP pinout adheres to the JEDEC evolutionary standard
for the four megabit device. Both the DIP and CSOJ packages are
pin for pin upgrades for the single chip enable 128K x 8, the
EDI88128C. Pins 1 and 30 become the higher order addresses.
A Low Power version with Data Retention (EDI88512LP) is also
available for battery backed applications. Military product is
available compliant to Appendix A of MIL-PRF-38535.
■ 32 lead JEDEC Approved Evolutionary Pinout
• Ceramic Sidebrazed 600 mil DIP (Package 9)
• Ceramic SOJ (Package 140)
■ Single +5V (±10%) Supply Operation

RECOMMENDED OPERATING CONDITIONS
NOTE:
Stress greater than those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions greater than those indicated in the operational sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect reliability.
