ST STM705 STM706 STM707 STM708 STM813L handbook
This document provides the specifications and features for the STM705, STM706, STM707, STM708, and STM813L 5 V supervisor devices. These self-contained devices provide microprocessor supervisory functions by monitoring the VCC input for out-of-tolerance conditions and forcing the reset output accordingly. They also offer a watchdog timer (except for STM707/708) and a power-fail comparator to provide early warning of impending power failure.
