STK10C68-P45I Datasheet PDF – 8K x 8 Nonvolatile Static RAM

Part Number : STK10C68-P45I

Function : High Performance 8K x 8 nvSRAM CMOS nonvolatile static RAM

Package : 28 Pin DIP or SOIC Type

Manufacturers : Simtek Corporation

Pinouts :

STK10C68-P45I datasheet


Description :

The Simtek STK10C68 is a fast static RAM(25, 30, 35, and 45ns), with a nonvolatile electrically-erasable PROM (EEPROM) element incorporated in each static memory cell. The SRAMcan be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data may easily be transferred from the SRAMto the EEPROM (STORE), or from the EEPROMto the SRAM(RECALL) using the NE pin. It combines the high performance and ease of use of a fast SRAMwith nonvolatile data integrity.


1. 25, 30, 35 and 45ns Access Times
2. 12, 15, 20 and 25ns Output Enable Access
3. Unlimited Read and Write to SRAM
4. Hardware STORE Initiation
5. Automatic STORE Timing
