描述 Description

The PCF85063BTL is a CMOS Real-Time Clock (RTC) and calendar optimized for lowpower consumption. An offset register allows fine-tuning of the clock. All addresses anddata are transferred serially via a Serial Peripheral Interface (SPI?bus) with a maximumdata rate of 7?Mbit/s. The register address is incremented automatically after eachwritten or read data byte.
