The CMOS bq3285ED/LD is a low-power microprocessor peripheral providing a time-of-day clock and 100-year calendar with alarm features and battery operation. The architecture is based on the bq3285/7 RTC with added features: low-voltage operation, 32.768kHz output, 128 additional bytes of CMOS, and a day-of-month alarm to be compliant with the ACPI RTC specification.
A 32.768kHz output is available for sustaining power-management activities. The bq3285ED/LD 32kHz output is always on whenever VCC is valid. In VCC standby mode, the 32kHz is active, and the bq3285LD typically draws 100uA while the bq3285ED typically draws 300uA. Wake-up capability is provided by an alarm interrupt, which is active in battery-backup mode.
