SUMMARY DESCRIPTION
The STM70x Supervisors are self-contained de-
vices which provide microprocessor supervisory
functions. A precision voltage reference and com-
parator monitors the V
ance condition. When an invalid V
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 compar-
ator 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.
