DESCRIPTION

The DS1283 Watchdog Timekeeper Chip is a self–contained real time clock, alarm, watchdog timer, and interval timer in a 28–pin JEDEC DIP or 28–pin SOIC surface mount package. The DS1283 is specifically designed to maintain internal operations from a single low voltage supply. In fact, the only two external components required by the DS1283 are a battery and crystal.

FEATURES
