产品概述
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 non-rechargeable 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.
