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).
