NXP SC16IS740IPW Single UART with I2C-bus/SPI Interface

The NXP SC16IS740IPW is a single-channel Universal Asynchronous Receiver/Transmitter (UART) that significantly extends the serial communication capabilities of a host system. This integrated circuit is designed to provide a seamless interface for communication with peripheral devices or microcontrollers through its I2C-bus or SPI interface. The SC16IS740 is a perfect solution for applications that require additional UART interfaces when the host microcontroller has a limited number of built-in UARTs.

Key Features

• Flexible Serial Interface: The SC16IS740IPW offers a choice between a high-speed I2C-bus (up to 400 kbit/s) and a SPI interface (up to 4 Mbit/s), providing versatility for various system design requirements.
• 64-byte FIFO: Equipped with a deep 64-byte FIFO for both transmit and receive, the device ensures smooth data flow and reduces the load on the host processor, minimizing the risk of data loss during high-speed communications.
• Programmable Baud Rate Generator: The onboard programmable baud rate generator allows the user to configure the serial bit rate as needed for their specific application.
• Auto Hardware and Software Flow Control: The SC16IS740IPW supports automatic hardware and software flow control, enhancing reliability and preventing data overrun.
• RS-485 Driver Direction Control: The UART includes RS-485 driver direction control via the RTS signal, enabling efficient management of RS-485 bus collisions and data integrity during transmissions.
• Modem Interface Signals: In addition to the standard UART signals, the device provides full modem interface signals to facilitate a wide range of communication tasks.
• Multiple Package Options: The SC16IS740IPW is available in a small TSSOP-16 package, making it suitable for space-constrained applications.

Applications

The NXP SC16IS740IPW is ideal for a broad range of applications, including industrial automation, point-of-sale systems, and any embedded system that requires additional UART channels. Its ability to interface with a variety of microcontrollers and processors makes it a versatile choice for designers looking to expand their system's communication capabilities without significant redesign.

Overall, the NXP SC16IS740IPW is a highly integrated UART interface solution that offers a balance of performance, power efficiency, and design flexibility, making it an essential component for modern serial communication needs.
