XR20M1280IL40TR-F Overview
The QFN package is the most cost-effective.Transmission uses 16 channels.Its uPs/uCs/Peripheral ICs type is SERIAL IO/COMMUNICATION CONTROLLER, I2C BUS.As part of its configuration, it uses 40 terminations.UART operates on 3.3V supply voltage.As a way to communicate data, the board has 1 serial I/Os.There are 40 pins on this electronic device.24MHz is the clock frequency of this integrated circuit.UART is important that the operating temperature does not exceed -40°C in order for the machine to perform normally for a long time.It is important to keep the operating temperature below 85°C to ensure a long working period.When the supply voltage is kept below 3.63V, reliability can be assured.Keeping the supply voltage above 1.62V ensures reliability.
