Description
This MAX 1232 microprocessor (μP) supervisory circuit provides μP housekeeping and power-supply supervision functions. All while consuming only 1/10th the power of the DS1232. This device enhances circuit reliability in μP systems by monitoring the power supply, monitoring the software execution, and providing a debounced manual reset input. The MAX1232 is a plug-in upgrade of the Dallas DS1232.
A reset pulse of at least 250ms duration is supplied on power-up, power-down, and low-voltage brownout conditions (5% or 10% supply tolerances can be selected digitally). Also featured is a debounced manual reset input. This forces the reset outputs to their active states for a minimum of 250ms.
A digitally programmable watchdog timer monitors software execution. You can program it for timeout settings of 150ms, 600ms, or 1.2s. The MAX1232 requires no external components.
