App Note 101: Using the Secure Microcontroller Watchdog Timer
The Secure Microcontroller Family (DS5000FP, DS5001FP, DS5002FP, and associated modules) integrate an internal watchdog timer to prevent code execution errors. The watchdog timer uses the high precision crystal oscillator that is also used by the microcontroller. This eliminates the need for a RC oscillator while providing greater accuracy.
Overview
Microcontrollers are often used in harsh environments where power supply transients, electromagnetic interference (EMI), and electrostatic discharge (ESD) are abundant. Program corruption caused by bus corruption and electromagnetic discharges can...
