1. General description
The PCF85063A is a CMOS
1
Real-Time Clock (RTC) and calendar optimized for low
power consum p tion . An offset regis ter allow s fine -tuning of the clock. All add re sses an d
data are transferred serially via the two-line bidirectional I
2
C-bus. Maximum data rate is
400 kbit/s. The register address is incremented automatically after each written or read
data byte.
For a selection of NXP Real-Time Clocks, see Table 45 on page 56
