The SC16IS740IPW,112 is a single UART IC, provides slave I²C-bus/SPI Interface to a single-channel high performance UART. It offers data rates up to 5Mbps and guarantees low operating and sleeping current. This family of products enables seamless protocol conversion from I²C-bus or SPI to and RS-232/RS-485 and are fully bidirectional. Its internal register set is backward-compatible with the widely used and widely popular 16C450. This allows the software to be easily written or ported from another platform. It also provides additional advanced features such as auto hardware and software flow control, automatic RS-485 support and software reset. This allows the software to reset the UART at any moment, independent of the hardware reset signal.
