The Texas Instruments BQ3285ESSTR is a Real Time Clock (RTC) IC featuring a parallel interface for clock and calendar functions. This component provides a 242B NVSRAM for data storage and supports alarms, daylight savings, and leap year calculations. The device operates with a supply voltage range of 4.5V to 5.5V, and its battery backup input ranges from 2.5V to 4V. With a timekeeping current draw of 300µA at 5V, it is suitable for applications requiring continuous timekeeping. The BQ3285ESSTR offers both 12-hour and 24-hour time formats, with date formatting in YY-MM-DD-dd. It is supplied in a 24-SSOP (0.154", 3.90mm Width) package, designed for surface mounting. This RTC is commonly utilized in industrial control, consumer electronics, and computing systems.
