PCA85063ATT中文资料Automotive tiny Real-Time Clock/calendar with alarm function and I²C-bus数据手册恩XP规格书

描述 Description

The PCA85063A 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 the two-line bidirectional I²C-bus. The maximum data rate is400 kbit/s. The register address is incremented automatically after each written or readdata byte.
