Description
The bq3285ED/LD is a low-power microprocessor peripheral that provides a time-of-day clock, 100-year calendar, alarm features, and battery operation. It is based on the bq3285/7 RTC with added features, including low-voltage operation, 32.768kHz output, 128 additional bytes of CMOS, and a day-of-month alarm to comply with the ACPI RTC specification.
Features
ACPI-compliant day-of-month alarm
Direct clock/calendar replacement for IBM AT-compatible computers and other applications
2.7-5.5V operation (bq3285LD); 4.5-5.5V operation (bq3285ED)
242 bytes of general nonvolatile storage
Dedicated 32.768kHz output pin
System wake-up capability - alarm interrupt output active in battery-backup mode
Less than 0.55μA load under battery operation
Selectable Intel or Motorola bus timing
Applications
IBM AT-compatible computers
Other applications requiring a time-of-day clock, calendar, and alarm features
