STM706/708T/S/R 3V supervisor is a low power device with a precision VCC monitor, RST and RST outputs, 200ms (typ.) trec, 1.6 s (typ.) watchdog timer, manual reset input (MR), power-fail comparator (PFI/PFO).
This document is a datasheet for the STM706T/S/R, STM706P, and STM708T/S/R 3V supervisor devices from STMicroelectronics. These self-contained integrated circuits provide microprocessor supervisory functions by monitoring the VCC input for out-of-tolerance conditions. When an invalid voltage condition occurs, the device forces the reset output low or high, depending on the specific model variant.
