SUMMARY DESCRIPTION

The STM70x Supervisors are self-contained de-

vices which provide microprocessor supervisory

functions. A precision voltage reference and com-

parator monitors the VCC input 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).

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.
