PCF85063ATL - NXP

PCF85063ATL Tiny Real-Time Clock/calendar

The PCF85063ATL is a CMOS1 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 the two-line bidirectional I2C-bus. Maximum data rate is 400 kbit/s. The register address is incremented automatically after each written or read data byte. .
