Description

The SC16IS740IPW,112 is a UART (Universal Asynchronous Receiver Transmitter) electronic component that provides a slave I2C-bus/SPI interface to a single-channel high-performance UART. It allows data rates up to 5 Mbit/s and guarantees low operating and sleeping current. It also offers seamless protocol conversion from I2C-bus or SPI to and RS-232/RS-485 and is fully bidirectional.
