The SC16IS750 from NXP Semiconductors is a single Universal Asynchronous Receiver/Transmitter (UART) with I2C-bus (up to 3.4 Mbit/s) and SPI (up to 4 Mbit/s) interfaces. This versatile device is designed to serve as an interface between the standard UART port of a microcontroller and the serial I2C-bus or SPI, allowing for a seamless expansion of serial communication ports with minimal hardware adjustments.

The SC16IS750 is equipped with a comprehensive set of features that make it ideal for applications that require a bridge between a legacy serial interface and a modern serial bus. It is particularly useful in systems where more UARTs are needed than what is available on the host microcontroller or when a fast and straightforward way to add serial connectivity is necessary.

Key Features:

• Fully Compatible with I2C-bus and SPI Interface: This allows for easy integration with a host microcontroller via two of the most common serial communication protocols.
• Auto Hardware Flow Control: With its built-in hardware flow control, the SC16IS750 ensures reliable data transfer, reducing the risk of data loss in high-speed communication scenarios.
• Programmable Baud Rate Generator: The device can be programmed for any baud rate from 5 bps to 3.6864 Mbps, providing flexibility for various communication requirements.
• 64-byte FIFO: Each UART contains a 64-byte transmit and receive FIFO, which greatly reduces the overhead required to manage the serial communication data.
• Modem Interface: The SC16IS750 supports modem interface signals, making it suitable for modem control applications.
• Low Power Consumption: It is designed with power conservation in mind, making it suitable for battery-powered and power-sensitive applications.
• Multiple Package Options: Available in a variety of packages, including QFN, TSSOP, and HVQFN, providing flexibility for different design requirements.

Whether you're developing industrial control systems, point-of-sale terminals, or any application that requires additional UART capabilities, the SC16IS750 offers a reliable, high-performance solution that simplifies design and reduces time to market.
