The BQ3285ESS from Texas Instruments is a low-power microprocessor peripheral providing a time-of-day clock and 100-year calendar with alarm features and battery operation. It is functionally compatible with the DS1285 and closely matches the MC146818A pin configuration.
This Real Time Clock (RTC) features a parallel interface and operates within a voltage range of 2.5V to 4V. It offers 242 bytes of general nonvolatile storage and includes features such as alarm interrupt, daylight saving adjustment, leap year calculation, and a square wave output. The device supports both 12-hour and 24-hour time formats, as well as YY-MM-DD-dd date format.
Designed for surface mounting, the BQ3285ESS is housed in a 24-SSOP package with a width of 3.90mm. It requires minimal external components, typically a 32.768kHz crystal and a backup battery. The device provides wake-up capability via an alarm interrupt active in battery-backup mode and protects clock, calendar, and storage registers during power failure.
Key electrical characteristics include a typical operating current of 300µA at 5V. The operating temperature range is from 0°C to 70°C. The device is RoHS3 compliant and has an MSL rating of 1.
