Watchdog Timeout Period Externally Adjustable Voltage Detector
The XC6130 series are voltage detectors with a watchdog function. The watchdog timeout time and release delay time can be set as desired using a single external capacitor. These voltage detectors are used for microprocessor monitoring, and when the power voltage reaches the detect voltage or an L→H pulse is not input to the watchdog pin within the watchdog timeout time, an L level signal is output from the RESETB pin.
The XC6130 series has a manual reset function. When the manual reset pin is set to Low level at any desired timing, an L level signal is output from the RESETB pin.

What does the watchdog timer work?
This timer function is continuously monitoring to check whether the microcomputer is normally operating or not and give notice of any abnormal operation.
