Description

The STM70x supervisors are self-contained devices which provide microprocessor

(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 is identical to the STM706R, 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.
