The STK16C68 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. 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 con-  
trol sequences on the SRAM inputs. The STK16C68 is  
pin-compatible with 8k x 8 SRAMs and battery-backed  
SRAMs, allowing direct substitution while enhancing  
performance. The STK12C68, which uses an external  
capacitor, and the STK15C68, which uses charge  
stored in system capacitance, are alternatives for sys-  
tems needing AutoStore™ operation.
