Description
The STM70x supervisors are self-contained devices which provide microprocessor
supervisory functions. A precision voltage reference and comparator monitors the V
for an out-of-tolerance condition. When an invalid V
(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.
