Tiny Real-Time Clock/Calendar with Alarm Function and SPI‑Bus
PCF85063B Receive alerts
The PCF85063BTL is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via a Serial Peripheral Interface (SPI‑bus) with a maximum data rate of 7 Mbit/s. The register address is incremented automatically after each written or read data byte.
