The MAX3100 universal asynchronous receiver transmit ter (UART) is the first UART specifically optimized for small microcontroller-based systems. Using an SPI™/Microwire™ interface for communication with the host microcontroller (µC), the MAX3100 comes in a compact 16-pin QSOP. The asynchronous I/O is suitable for use in RS-232, RS-485, IR, and opto-isolated data links. IR-link communication is easy with the MAX3100’s infrared data association (IrDA) timing mode.
