Introduction
The BQ32002 device is a compatible replacement for industry standard real-time clocks. The BQ32002 features an automatic backup supply that can be implemented using a capacitor or nonrechargeable battery. The BQ32002 has a programmable calibration adjustment from –63 ppm to +126 ppm. The BQ32002 registers include an OF (oscillator fail) flag indicating the status of the RTC oscillator, as well as a STOP bit that allows the host processor to disable the oscillator. The time registers are normally updated once per second, and all the registers are updated at the same time to prevent a timekeeping glitch. The BQ32002 includes automatic leap-year compensation.
Features
- Automatic Switchover to Backup Supply
- I²C Interface Supports Serial Clock up to 400 kHz
- Uses 32.768-kHz Crystal With –63-ppm to +126-ppm Adjustment
- Integrated Oscillator-Fail Detection
- 8-Pin SOIC Package
- -40 ℃ to +85 ℃ Ambient Operating Temperature
Applications
- General Consumer Electronics
