The BQ4845YS-A4N from Texas Instruments is a low-power Real-Time Clock (RTC) integrated circuit designed for time-of-day clock, 100-year calendar, and CPU supervision functions. It features a parallel interface and is housed in a 28-pin SOIC package, suitable for surface mounting.
Key electrical specifications include an operating voltage range of 2.3V to 4V and a typical current consumption of 1.5mA. The device operates across a temperature range of -40°C to 85°C. Its features include an on-chip battery-backup switchover circuit, a watchdog timer with a programmable time-out period, power-fail interrupt warning, and programmable clock alarm and periodic interrupts.
This RTC is ideal for applications requiring accurate timekeeping and system supervision, such as fax machines, copiers, industrial control systems, point-of-sale terminals, data loggers, and computers. The on-chip battery-backup ensures continuous operation and data retention during system power loss.
The BQ4845YS-A4N supports both 12/24 hour time formats and YY-MM-DD-dd date formats. It also includes features like daylight savings and leap year calculations, making it a versatile component for various embedded systems.
