Introduction: Although 3.3V is becoming increasingly popular in modern microcontrollers, and general system designs tend to adopt lower supply voltages, the 5V voltage level still holds significant importance and remains a popular design choice. This is mainly due to the higher voltage of 5V providing better anti-interference capabilities and stability in signal transmission, along with … Read more
The “independence” of the built-in watchdog in MCUs is typically reflected in its hardware isolation from core processing units (such as CPUs and buses), for example, having independent clock sources, counters, and reset logic. This ensures that even if the CPU becomes unresponsive due to software bugs or hardware failures, the built-in watchdog can still … Read more
