Simtek STK16C88
The STK16C88 is a fast SRAM with a nonvolatile EEPROM element incorporated in each static memory cell. The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. The STK16C88 is pin-compatible with 32k x 8 SRAMs and battery-backed SRAMs, allowing direct substitution while enhancing performance.- Min Voltage : 4.5V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

DESCRIPTION
Data transfers from the SRAM to the EEPROM (the STORE operation) can take place automatically on power down. An internal capacitor guarantees the STORE operation regardless of power-down slew rate. Transfers from the EEPROM to the SRAM (the RECALL operation) take place automatically on restoration of power. Initiation of STORE and RECALL cycles can also be controlled by entering control sequences on the SRAM inputs.
