Description
PCF8523T/1,118 NXP Calendar Real Time Clock Serial Clock/Calendar/Alarm/Timer/Battery Backup 2-Wire Serial 8-SOIC RoHSThe PCF8523 is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. Data is transferred serially via the I2C-bus with a maximum data rate of 1000 kbit/s. Alarm and timer functions are available with the possibility to generate a wake-up signal on an interrupt pin. An offset register allows fine-tuning of the clock. The PCF8523 has a backup battery switch-over circuit, which detects power failures and automatically switches to the battery supply when a power failure occurs.
