STK16CA8  
128K x 8 AutoStorePlus™ nvSRAM  
QuantumTrap™ CMOS  
Nonvolatile Static RAM  
Preliminary  
FEATURES  
DESCRIPTION  
• 25ns, 35ns and 45ns Access Times  
The Simtek STK16CA8 is a fast static RAM with a  
nonvolatile element in each static memory cell. The  
embedded nonvolatile elements incorporate  
Simtek’s QuantumTrap™ technology producing the  
world’s most reliable nonvolatile memory. The SRAM  
provides unlimited read and write cycles, while inde-  
pendent, nonvolatile data resides in the nonvolatile  
elements. Data transfers from the SRAM to the non-  
volatile elements (the STORE operation) can take  
place automatically on power down or under soft-  
ware control. An internal capacitor guarantees the  
STORE operation, even under extreme power-down  
slew rates or loss of power from “hot swapping”.  
Transfers from the nonvolatile elements 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. The STK16CA8 is  
pin-compatible with 128k x 8 SRAMs and battery-  
backed SRAMs, allowing direct substitution while  
providing superior performance.  
• Directly Replaces 128K x 8 Static RAM, Bat-  
tery-Backed RAM or EEPROM  
• Transparent Data Save on Power Down  
STORE to QuantumTrap™ Nonvolatile Ele-  
ments is Initiated by Software or AutoStore-  
Plus™on Power Down  
RECALL to SRAM Initiated by Software or  
Power Restore  
• 5mA Typical ICC at 200ns Cycle Time  
• Unlimited READ and WRITE Cycles to SRAM  
• 100-Year Data Retention to Quantum Trap  
• Single 3V +20%, -10% Operation  
• Commercial and Industrial Temperatures  
• 32-Pin DIP Package
