产品概述
The bq32000 device is a compatible replacement for industry standard real-time
clocks.The bq32000 features an automatic backup supply with integrated trickle charger. The
backup supply can be implemented using a capacitor or non-rechargeable battery. The bq32000 has a
programmable calibration adjustment from –63 ppm to +126 ppm. The bq32000 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
bq32000 includes automatic leap-year compensation.
