Additional Details:

The XC6420AB35MR-G has a specific detection voltage (3.5V, as indicated by '35' in the part number), which is the voltage level at which the reset signal is asserted. The IC typically operates with a supply voltage range of 1.5V to 5.5V. The open-drain output requires an external pull-up resistor. The hysteresis feature prevents spurious resets when the input voltage is close to the detection threshold. It is compliant with RoHS environmental standards.
