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.

Questions answered in these manuals
What is the typical supply current of these supervisors?
The typical supply current is 40 µA.
Do all models include a watchdog timer?
No, the watchdog timer is available for STM705/706/813L but not for STM707/708.
What is the watchdog timer timeout period for the STM705/706/813L devices?
The watchdog timer timeout is 1.6 seconds typical.

What is the operating temperature range of the STM705/706/707/708/813L supervisors?
They operate from –40 °C to 85 °C (Industrial Grade).
From: STMICROELECTRONICS - STM705 STM706 STM707 STM708 STM813L handbook
What is the function of the watchdog timer?
If the WDI pin remains high or low for 1.6 s, the internal watchdog timer expires and the reset (or WDO) output is triggered.
What package types are available for the STM706 family?
The devices are offered in a standard 8‑pin SOIC (SO8) package and a space‑saving 8‑pin TSSOP package.
