DESCRIPTION

The X1226 device is a Real Time Clock with

clock/calendar, two polled alarms with integrated

512x8 EEPROM, oscillator compensation, and battery

backup switch.

The oscillator uses an external, low-cost 32.768kHz

crystal. All compensation and trim components are

integrated on the chip. This eliminates several external

discrete components and a trim capacitor, saving

board area and component cost.
