FEATURES  
DESCRIPTION  
• Data Integrity of Simtek nvSRAM Combined  
The Simtek STK17CA8 combines a 1 Mbit nonvola-  
tile static RAM with a full-featured real-time clock in  
a reliable, monolithic integrated circuit. The embed-  
ded nonvolatile elements incorporate Simtek’s  
QuantumTrap™ technology producing the world’s  
most reliable nonvolatile memory. The SRAM can be  
read and written an unlimited number of times, while  
independent, nonvolatile data resides in the nonvol-  
atile elements.  
with Full-Featured Real-Time Clock  
• 25ns, 35ns and 45ns Access Times  
• Software or AutoStoreSTORE to Quan-  
tumTrap™ Nonvolatile Elements  
RECALL to SRAM Initiated by Software or  
Power Restore  
• Unlimited READ, WRITE and RECALL Cycles  
• 100-Year Data Retention  
• Watchdog Timer  
The Real-Time Clock function provides an accurate  
clock with leap year tracking and a programmable,  
high accuracy oscillator. The Alarm function is pro-  
grammable for one-time alarms or periodic seconds,  
minutes, hours, or days. There is also a programma-  
ble Watchdog Timer for process control.  
• Clock Alarm with programmable Interrupts  
• Capacitor or battery backup for RTC  
• Single 3V +20%, -10% Operation  
• Commercial and Industrial Temperatures  
• Packages: 48 pin SSOP, 40 pin DIP
