2线串行接口

The Rx5C348 are CMOS real-time clock ICs connected to the CPU by four signal lines, CE, SCLK, SI, SO, and configured to perform serial transmission of time and calendar data to the CPU. The periodic interrupt circuit is configured to generate interrupt signals with six selectable interrupts ranging • Timekeeping supply voltage：1.45 to 5.5 V；\n• Supply Current：Rx5C348A: Typ. 0.35 µA (VDD=3V),Rx5C348B: Typ. 0.55 µA (VDD=3V)；\n• Connected to the CPU：Four signal lines (CE, SCLK, SI, and SO), Maximum clock frequency of 2 MHz (with VDD = 5V)；\n• Functions：Time counters (counting hours, minutes, and ;
