BQ32002D Description

Short technical summary and product information.

The BQ32002D is a real-time clock (RTC) from Texas Instruments, integrating a clock/calendar with I2C interface. It supports 24-hour time format (HH:MM:SS) and date format YY-MM-DD-dd. The device includes leap-year compensation, a square wave output, and a trickle-charger for backup supply. It operates from a supply voltage of 1.4V to 3.6V, with a typical timekeeping current of 200µA at 3.3V. The operating temperature range is -40°C to 85°C.

 

Key features include automatic switchover to a backup supply (capacitor or non-rechargeable battery), integrated oscillator-fail detection, and a programmable calibration adjustment from -63 ppm to +126 ppm for crystal frequency trimming. The I2C interface supports serial clock up to 400 kHz. The device is packaged in an 8-pin SOIC (0.154", 3.90mm width) for surface mount assembly.

 

This RTC is suitable for a wide range of applications requiring precise timekeeping with battery backup, including industrial controllers, embedded systems, and consumer electronics. Its low power consumption and small footprint make it ideal for space-constrained designs.
