Working Principles

The S-8264AAE-I8T1U operates by continuously monitoring the supply voltage connected to its VDD pin. It compares the detected voltage against a preset threshold and generates a reset signal on the RST pin if the voltage falls below the threshold. Additionally, the watchdog timer monitors the WDI pin for periodic software or hardware signals. If no activity is detected within the specified timeout period, the IC triggers a reset signal to prevent system lock-ups.
