Description

The STM70x supervisors are self-contained devices which provide microprocessor

supervisory functions. A precision voltage reference and comparator monitors the VCC input

for an out-of-tolerance condition. When an invalid VCC condition occurs, the reset output

(RST) is forced low (or high in the case of RST).

These devices also offer a watchdog timer (except for STM708T/S/R) as well as a power-fail

comparator to provide the system with an early warning of impending power failure.

The STM706P device is identical to the STM706R device, except its reset output is active

high. These devices are available in a standard 8-pin SOIC package or a space-saving 8-pin

TSSOP package.
