概述
Description
The PCF8563TS/4 is a low-power CMOS real-time clock (RTC) and calendar IC from NXP. It provides timekeeping (seconds to years) with alarm and timer functions, operating on a 1.8V–5.5V supply.
Key features:
- I²C-bus interface (400 kHz max) for communication.
- Programmable clock output (32.768 kHz to 1 Hz).
- Ultra-low power (~0.25 µA typical at 3V).
- Integrated oscillator capacitor (no external components needed).
- Battery backup support for continuous timekeeping.
Applications include embedded systems, smart meters, wearables, and IoT devices. The TS/4 variant comes in a TSSOP8 package.
For setup, configure via I²C, initialize time/date registers, and optionally enable alarms or clock output.
