The XC61FN1812MR-G with Supervisory Circuits is a low power, single-chip supervisor IC manufactured by Torex Semiconductor. It features an ultra-low voltage detection circuit, a reset circuit, a power-on reset circuit, a watchdog timer (WDT) reset circuit, and a clock output circuit.The ultra-low voltage detection circuit is designed to detect voltages as low as 0.8V, enabling the device to operate even at lower supply voltages. The reset circuit can be set to output a low level signal when the voltages fall below the set level. The power-on reset circuit can generate a reset output when the supply voltage is applied.The WDT reset circuit monitors the period of time between the reset outputs, and generates a reset signal when the interval exceeds the set time. The clock output circuit can generate a high-accuracy square wave clock signal (32.768 kHz).The XC61FN1812MR-G provides high accuracy and stable reset operation, making it ideal for embedded microcontroller designs requiring reset and control functions.
