Part Number : STK10C68-P45I
Function : High Performance 8K x 8 nvSRAM CMOS nonvolatile static RAM
Package : DIP, SOIC, LCC 28 Pin Type
Maker : Simtek Corporation
Pinouts : 
Description :
The Simtek STK10C68-P45I, 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.
Features
• 20ns, 25ns, 35ns and 45ns Access Times
• STORE to EEPROM Initiated by Hardware
• RECALL to SRAM Initiated by Hardware or Power Restore
• Automatic STORE Timing
