The MAX3107ETG+T with UART Interface IC is an integrated circuit (IC) designed by Analog Devices with a high-performance, low-power UART 3.0 compatible interface that allows direct connection to an asynchronous SPI/I2C bus. This device features a 128-word FIFO, internal oscillator for baud rate generation, and multiple operating modes including standard, autobauding, multiprocessor, and wake-up receiver. It also features an integrated Peripheral Self-Test (PST) feature to detect communication faults and alert the user. This IC is designed to operate up to a maximum operating temperature of 125°C, and power requirements range between 1.8V and 3.6V.
