Power Supply Monitoring: Monitors the VCC supply voltage and generates an active-low reset (RST) and active-high reset (RST) signal when an out-of-tolerance condition occurs.Watchdog Timer: Includes a watchdog timer that monitors software execution. If the watchdog input (STROBE) is not toggled low within a specified timeout period (e.g., 1.2 seconds, 600ms, or 150ms depending on variant and configuration), it forces the reset signals to the active state.Pushbutton Reset Control: Incorporates a pushbutton reset control function, debouncing the input and guaranteeing an active reset pulse width of at least 250ms.Automatic Restart after Power Failure: Automatically restarts the microprocessor after power failure by holding reset active until the power supply and processor stabilize (at least 250ms).Accuracy: Offers accurate 5% or 10% microprocessor power supply monitoring, selectable via the TOL pin.Low Power Consumption: Features a low quiescent current, typically 50µA, making them suitable for low-power applications.Wide Operating Temperature Range: Standard versions operate from 0°C to 70°C, while industrial versions (designated by "N" or sometimes "-I") operate from -40°C to +85°C.Reset Threshold Options: Different variants may offer different VCC reset thresholds (e.g., 4.75V or 4.5V).
