Description
The MAX1232 microprocessor (µP) supervisory circuit provides µP housekeeping and power-supply supervision functions while consuming only 1/10th the
power of the DS1232. The MAX1232 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 that forces the reset outputs to their active states for a minimum of 250ms. A digitally
programmable watchdog timer monitors software execution and can be programmed for timeout settings of 150ms, 600ms, or 1.2s. The MAX1232 requires
no external components.
