BL5372 Datasheet (SHANGHAI BELLING) - Low-power real-time clock chip

BL5372, Low-power real-time clock chip

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.

The BL5372 can generate various periodic interrupt clock pulses lasting for long period (one month), and alarm interrupt can be made by two incorporated syst
