Description
The BL5372 is a CMOS type real-time clock, which is connected to the CPU via two wires and capable of serial transmission of clock to the CPU.
Features
- Lowest supply current: 400nA TYP. @ 5V.
- Connected to the CPU via only 2-wires
(MAX. 100KHz).
- A clock counter (counting hours, minutes,
and seconds) and a calendar counter (counting leap years, years, months, days, and days of the week) in BCD codes.
- Two systems output providing interrupt to the CPU output (period of one month to one second, interrupt halt function).
- Two systems output of alarm functions.
- Oscillation halt sensing to judge internal data validity.
