TEXAS INSTRUMENTS BQ32000DR 芯片, 实时时钟, 串口, 8SOIC
The is a serial Real-time Clock IC features an automatic backup supply with integrated trickle charger. The backup supply can be implemented using a capacitor or non-rechargeable battery. The BQ32000DR has a programmable calibration adjustment from -63 to +126ppm. The BQ32000DR 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 BQ32000DR includes automatic leap-year compensation. The BQ32000DR is a compatible replacement for industry standard real-time clocks.
