BQ4802LYDW Description

Short technical summary and product information.

The BQ4802LYDW from Texas Instruments is a parallel real-time clock (RTC) integrated circuit designed for applications requiring accurate timekeeping and system supervision. This device functions as a clock/calendar, supporting both 12/24 hour time formats and YY-MM-DD-dd date formats. It includes essential features such as an alarm, daylight savings adjustment, leap year calculation, an integrated CPU supervisor, and a watchdog timer.

 

The BQ4802LYDW operates within a voltage range of 2.4V to 4V and has a typical operating current of 1.5mA. It is specified for an operating temperature range of 0°C to 70°C. The device features a parallel bus interface for communication and requires a 28-pin SOIC package for surface mounting.

 

This RTC is suitable for various applications including telecommunications, base stations, servers, handheld data collection equipment, medical equipment, handheld instrumentation, and test equipment. Its low backup current of less than 500 nA makes it efficient for battery-backed operation.
