实时时钟, 日期时间格式 年-月-日-星期, 时:分:秒, I2C, 0.9V至5.5V电源, DFN2626-10

Overview

The PCF85363A is a CMOS Real-Time Clock RTC and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch elapsed time counter. Three time log registers triggered from battery switch-over as well as input driven events. Featuring clock output and two independent interrupt signals, two alarms, I²C interface and quartz crystal calibration, 64 byte battery backed-up RAM.
