Note a: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only, and functional operation of the device at conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The Simtek STK17TA8 combines a 1 Mbit nonvolatile static RAM with a full-featured real-time clock in a reliable, monolithic integrated circuit. The embedded 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 nonvolatile elements.

The Real-Time Clock function provides an accurate clock with leap year tracking and a programmable,high accuracy oscillator. The Alarm function is programmable for one-time alarms or periodic seconds,minutes, hours, or days. There is also a programmable Watchdog Timer for process control.
