PCF85363ATT - Tiny Real-Time Clock/calendar with 64 byte RAM, alarm function, battery switch-over time stamp input, and I2C-bus - 具有I²C接口的RTC - I²C - 恩智浦, LLC
The PCF85363A is a CMOS Real-Time Clock (RTC) and calendar optimized for lowpower consumption and with automatic switching to battery on main power loss. The RTCcan also be configured as a stop-watch (elapsed time counter). Three time log registerstriggered from battery switch-over as well as input driven events. Featuring clock outputand two independent interrupt signals, two alarms, I2C interface and quartz crystalcalibration, 64 byte battery backed-up RAM.
