DS1232N MicroMonitor Chip: Diagram, Pinout, and Datasheet

The DS1232N MicroMonitor^TM Chip keeps track of three critical microprocessor conditions: power, program execution, and external override. The status of VCC is first monitored by a precision temperature-compensated reference and comparator circuit. An internal power fail signal is created when an out-of-tolerance event occurs, forcing a reset to the active state. The reset signals are kept active for a minimum of 250 milliseconds after VCC returns to an in-tolerance condition to allow the power supply and processor to recover.

The DS1232N's second function is to control the reset button. The DS1232 debounces the pushbutton input and ensures a 250 ms minimum active reset pulse width. A watchdog timer is the third feature. If the strobe input is not driven low before timeout, the DS1232's internal timer pushes the reset signals to the active state. The watchdog timer function can be programmed to operate at 150 milliseconds, 600 milliseconds, or 1.2 seconds.
