EDI8F81024C 1Megx8 Static RAM CMOS, Module FEATURES DESCRIPTION 1024Kx8 bit CMOS Static The EDI8F81024C is a 8Mb CMOS Static RAM based on eight 128Kx8 Static RAMs mounted on a multi-layered epoxy laminate (FR4) substrate. Random Access Memory Access Times 70 thru 100ns A version featuring Low Power with Data Retention (EDI8F81024LP) is also available. Data Retention Function (EDI8F81024LP) TTL Compatible Inputs and Outputs The EDI8F81024C is offered in a double sided, 36 pin single-inline Package (SIP). Surface mount SIP technology is a cost effective solution to very high packing density requirements. Fully Static, No Clocks High Density Packaging All inputs and outputs are TTL compatible and operate from a single 5V supply. Fully asynchronous, the EDI8F81024C requires no clocks or refreshing for operation. 36 Pin SIP, No. 62 Single +5V (±10%) Supply Operation PIN CONFIGURATIONS AND BLOCK DIAGRAM PIN NAMES AØ-A19 Chip Enable W Write Enable G DQØ-DQ7 VCC Aug. 2001 Rev. 8 ECO #14552 1 Address Inputs E Output Enable Common Data Input/Output Power (+5V±10%) VSS Ground NC No Connection White Electronic Designs Corporation (508) 366-5151 www.whiteedc.com EDI8F81024C RECOMMENDED DC OPERATING CONDITIONS ABSOLUTE MAXIMUM RATINGS* Voltage on any pin relative to VSS Operating Temperature TA (Ambient) Commercial Industrial Storage Temperature Plastic Power Dissipation Output Current Parameter Supply Voltage Supply Voltage Input High Voltage Input Low Voltage -0.5V to 7.0V 0°C to +70°C -40°C to +85°C -55°C to +125°C 1 Watt 20 mA Sym VCC VSS VIH VIL Min 4.5 0 2.2 -0.3 Typ 5.0 0 --- Max 5.5 0 6.0 0.8 Units V V V V AC TEST CONDITIONS *Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
