Real-Time Clock (RTC)

The CMOS bq3285LD BQ3285ED is a low- power Microprocessor peripheral pro- viding a time-of-day Clock and 100- year calendar with alarm features and battery operation. The architec- ture is based on the bq3285/7 RTC with added features: low-voltage op- eration, 32.768kHz output, 128 addi- tional 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 ac- tivities. 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 100A while the BQ3285ED typically draws 300A. Wake-up capability is provided by an alarm interrupt, which is active in battery-backup mode. In battery- backup mode, current drain is less than 550nA. By Texas Instruments
