MAX3120ESA+ is an SPI-to-UART interface IC with integrated baud rate generator and FIFO buffers, ideal for embedded systems requiring simple serial communication expansion.

Product Overview

     The MAX3120ESA+ is a compact SPI-to-UART interface IC designed to add asynchronous serial (UART) capability to systems that lack a native UART port. It communicates with a host controller through an SPI interface and converts data to standard UART signals, supporting reliable serial communication with minimal firmware overhead. With an integrated baud rate generator and FIFO buffers, the MAX3120 simplifies serial expansion in embedded and industrial systems.
