EDI8L3265C

EDI8L3265C 64Kx32 SRAM Features 64Kx32 bit CMOS Static Random Access Memory Array • Fast Access Times: 12*, 15, 20, and 25ns • Individual Byte Selects • User Configurable Organization with Minimal Additional Logic 64Kx32 CMOS High Speed Static RAM The EDI8L3265C is a high speed, high performance, four megabit density Static RAM organized as a 64Kx32 bit array. Four Byte Selects, two 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 128Kx16 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 EDI8L3265C, allows 2 megabits of memory to be placed in less than 0.990 square inches of board space. The EDI8L3265C can be upgraded to 128K, 256K or 512Kx32 in the same footprint using the EDI8L32128, EDI8L32256 or the EDI8L32512C. (See page 6 for upgrade paths). Note: Solder Reflow temperatures should not exceed 260°C for 10 seconds. • Fully Static, No Clocks Surface Mount Package Single +5V (±5%) Supply Operation * Advance Information Pin Configurations and Block Diagram March 1997 Rev. 4 ECO #8302 T NO • Master Output Enable and Write Control • TTL Compatible Inputs and Outputs • 68 Lead PLCC, No. 99 (JEDEC-M0-47AE) • Small Footprint, 0.990 Sq.
