Product Overview
The PCF8523TK/1,118 is a CMOS Real-time Clock (RTC) and Calendar optimized for low power consumption. It provides year, month, day, weekday, hours, minutes and seconds based on a 32.768kHz quartz crystal. Data is transferred serially via the I²C-bus with a maximum data rate of 1000kbps. 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.
- Seconds to years resolution
- Battery backup input pin and switch-over circuit
- Freely programmable timer and alarm with interrupt capability
- Oscillator stop detection function
- Internal power-ON Reset (POR)
