128Kx32 CMOS High Speed Static RAM
FEATURES
128Kx32 bit CMOS Static Random Access Memory Array Fast Access Times: 12, 15, 17, 20, and 25ns Individual Byte Enables User Configurable Organization with Minimal Additional Logic Master Output Enable and Write Control TTL Compatible Inputs and Outputs Fully Static, No Clocks 68 Lead PLCC, No. 99 (JEDEC MO-47AE) Small Footprint, 0.990 Sq. In. Multiple Ground Pins for Maximum Noise Immunity
EDI8L32128C
DESCRIPTION
The EDI8L32128C is a high speed, high performance, four megabit density Static RAM organized as a 128Kx32 bit array. Four Chip Enables, Write Control, and Output Enable provide the user with a flexible memory solution. The user may independently enable each of the four bytes, and, with minimal additional peripheral logic, the unit may be configured as a 256Kx16 or 512Kx8 array. Fully asynchronous circuitry is used, requiring no clocks or refreshing for operation and providing equal access and cycle times for ease of use. The EDI8L32128C, allows 4 megabits of memory to be placed in less than 0.990 square inches of board space; a savings of 0.885 square inches over four standard 128Kx8 components.
