Overview
The SC16IS750IBS,157 is a single-channel high-performance UART (Universal Asynchronous Receiver-Transmitter) from NXP USA Inc. It serves as a slave I²C-bus/SPI interface, enabling seamless protocol conversion between I²C-bus or SPI and RS-232/RS-485. This device is particularly suited for handheld, battery-operated applications due to its low operating and sleeping current.
The SC16IS750IBS is part of the SC16IS740/750/760 family, which offers backward compatibility with the widely used 16C450, making software development and porting easier. The device supports various advanced features such as auto hardware and software flow control, automatic RS-485 support, and software reset.
