Product Overview: SC16IS750IPW,128 - NXP

The SC16IS750IPW,128 is a single UART (Universal Asynchronous Receiver/Transmitter) IC with I2C-bus/SPI interface, FIFOs, IrDA SIR built-in support, and an extensive set of enhanced features. Manufactured by NXP Semiconductors, this chip is designed to provide a simple and efficient way to add an extra UART to microcontroller-based systems.

Key Features

• Interface: The device supports both I2C and SPI protocols, allowing for easy integration with most microcontrollers and processors.
• High Data Rate: With the capability to transfer data at speeds up to 5 Mbps for SPI and 400 kbps for I2C, it is suitable for high-speed serial communication.
• FIFO Buffers: Integrated transmit and receive FIFO buffers (64 bytes each) help to reduce the number of interrupts presented to the host processor, thereby improving system efficiency.
• IrDA Support: The SC16IS750IPW,128 includes built-in support for IrDA SIR (Serial Infrared) communication, enabling infrared data communication.
• Programmable Baud Rate: The baud rate is programmable to accommodate a wide range of speeds for different applications.
• Enhanced Features: Additional features include automatic hardware and software flow control, sleep mode, and programmable Xon/Xoff characters.
• Supply Voltage: It operates at a range of voltages from 1.62V to 3.6V, allowing for flexibility in different system designs.

Applications

The SC16IS750IPW,128 is ideal for applications where an additional UART is necessary, particularly when board space is at a premium. It is commonly used in:

• Industrial control systems
• Point of Sale (POS) terminals
• Automotive diagnostics equipment
• Complex computing systems requiring additional serial interfaces

Conclusion

With its robust set of features and flexible interface options, the SC16IS750IPW,128 from NXP is an excellent choice for designers looking to expand the serial communication capabilities of their systems without the need for significant redesign or additional processors. Its support for high data rates and built-in FIFOs make it a reliable and efficient solution for a wide range of applications.
