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 AutoStore™STORE 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
