BQ32000DR Description

Short technical summary and product information.

The Texas Instruments BQ32000DR is a serial real-time clock (RTC) with an I2C (2-wire) interface. It provides clock/calendar functions with automatic leap-year compensation and supports a 24-hour time format with YY-MM-DD-dd date format.

 

Key electrical specifications include a supply voltage range of 1.4V to 3.6V and a typical timekeeping current of 100 µA at 3.3V. The device features a serial clock frequency of up to 400 kHz and uses a standard 32.768 kHz crystal. It offers programmable calibration adjustment from -63 ppm to +126 ppm and includes oscillator fail detection.

 

The BQ32000DR is housed in an 8-pin SOIC surface-mount package (8-SOIC, 0.154" width, 3.90mm width). It is specified for an operating temperature range of -40°C to 125°C, making it suitable for industrial and extended temperature applications.
