NXP SC16IS740IPW,112 UART Interface IC, Single Channel, TSSOP16

The NXP SC16IS740IPW,112 is a single-channel, high-performance UART interface IC that enables seamless protocol conversion between I2C-bus or SPI and RS-232/RS-485. It is fully bidirectional and supports data rates up to 5Mbit/s, ensuring efficient communication in industrial and portable applications.

This device is backward-compatible with the widely used 16C450 register set, allowing easy software development or porting from existing platforms. It includes advanced features such as auto hardware and software flow control, automatic RS-485 support, and software reset, which allows the UART to be reset at any time without relying on the hardware reset signal.

Key Features

• Single full-duplex UART with selectable I2C-bus or SPI interface
• 3.3V or 2.5V operation for flexible power supply design
• 64-byte FIFO for both transmitter and receiver, reducing CPU overhead
• Automatic RS-485 support for industrial networking
• Baud rates up to 5Mbit/s in 16 x clock mode
• Programmable Xon/Xoff characters for software flow control
• Independent enable/disable of transmitter and receiver
• Programmable receive and transmit FIFO levels with special character detection
• TSSOP16 package and industrial temperature range from -40°C to +95°C

The SC16IS740IPW,112 is ideal for factory automation, process control, battery-operated portable devices, and cellular data equipment, providing reliable and efficient serial communication in demanding environments.
