Part Number:TMS320F28069
Hi Champ;
Customer placed a 1uF capacitor between XRS and VSS for noise filtering and found the watchdog can reset the CPU normally under 25 degree, but when the amibent temperature go to 65 degree, the watchdog reset cannot CPU .
From the datasheert we know this capacitor should be 100 nF or smaller.
Customer wonder anything changed inside the chip under high temperature ? could you help on this question?
