General Description
The MAX 1232 microprocessor (µP) supervisory circuit provides µP ,housekeeping, and power-supply supervision functions while consuming only 1/10th the power of the DS1232. The MAX 1232 enhances circuit reliability in µP systems by monitoring the power supply, monitoring software execution, and providing a debounced manual reset input. The MAX 1232 is a plug-in upgrade of the Dallas DS 1232.
A reset pulse of at least 250ms duration is supplied on power-up, power-down, and low-voltage brown-out conditions (5% or 10% supply tolerances can be selected digitally). Alsto featured is a debounced manual reset input that forces the reset outputs to their active states for a minium of 250ms. A digitally-programmable wathdog timer monitors software execution and can be programmed fot timeout settings of 150ms, 600ms, or 1.2sec. The MAX 1232 requires no external components.
