Overview
The SC16IS741AIPWJ, produced by NXP USA Inc., is a high-performance single-channel UART (Universal Asynchronous Receiver-Transmitter) that integrates an I2C-bus/SPI interface. This device is designed to facilitate seamless protocol conversion between I2C-bus or SPI and RS-232/RS-485 interfaces, making it highly versatile for various applications. It operates at data rates up to 5 Mbit/s and is optimized for low operating and sleeping current, making it suitable for handheld and battery-operated devices. The SC16IS741AIPWJ is backward-compatible with the widely used 16C450 UART, simplifying software development and porting from other platforms.
