評価・開発ボードI²C-Bus RTC Demo Board
Automotive Tiny Real-Time Clock/Calendar with Alarm Function and I²C-Bus
PCA85073A アラートの受信
The PCA85073A 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.
