PCF8563T SOP8 PCF8563 SOP-8 8563T SOP SMD New and Original IC Chipset PCF8563 8563T SMD SOP8 real-time clock chip IC

PCF8563Real-time clock/calendar

General description

The PCF8563 is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption.

A programmable clock output, interrupt output, and voltage-low detector are also provided.

All addresses and data are transferred serially via a two-line bidirectional I2C-bus.

Maximum bus speed is 400 kbit/s.

The register address is incremented automatically after each written or read data byte.
