Product Introduction

Overview

The STWD100NXWY3F is a self-contained watchdog timer circuit produced by STMicroelectronics. This device is designed to prevent system failures caused by hardware errors such as non-responding peripherals and bus contention, or software errors like bad code jumps and code loops. The watchdog timer ensures that the system remains operational by periodically resetting the watchdog input within a specified timeout period. If the system fails to reset the watchdog, it generates a system alert and asserts the watchdog output.
