SUMMARY DESCRIPTION

The STM70x Supervisors are self-contained devices which provide microprocessor supervisory

functions. A precision voltage reference and comparator monitors the VCCinput for an out-of-toler

ance condition. When an invalid VCC condition occurs, the reset output (RST) is forced low (or

high in the case of RST).
