NXP SC16IS752IBS Dual UART with I2C-bus/SPI Interface

The NXP SC16IS752IBS is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) that greatly expands the serial communication capabilities of a host microcontroller via the I2C-bus or SPI interface. This product is designed to meet the needs of complex embedded systems that require additional serial interfaces when the number of hardware UARTs is insufficient or not available.

The SC16IS752IBS device is a perfect solution for applications that require high-speed serial data transfer, such as industrial control systems, point-of-sale terminals, and medical equipment. Its flexibility in interfacing with different microcontrollers makes it a versatile and essential component for system designers looking to enhance serial connectivity.

Key Features:

• Dual UART Channels: Offers two independent UART channels, each with a 64-byte FIFO (First In First Out) to reduce the overhead of CPU data management.
• I2C-bus/SPI Interface: Provides the option to interface with the host controller through either an I2C-bus (up to 3.4 Mbit/s) or an SPI interface (up to 4 Mbit/s), allowing for easy integration into various system architectures.
• Programmable Data Rate: Supports baud rates from 50 bps to 5 Mbps, which can be precisely generated using an onboard fractional baud rate generator.
• Modem Interface: Includes full modem interface signals, ensuring compatibility with a wide range of modems and other serial devices.
• IrDA SIR: Comes with built-in support for IrDA SIR (Serial Infrared) endec, enabling infrared serial communication for wireless connectivity.
• Auto Hardware Flow Control: Features automatic hardware flow control using CTS/RTS signals, which simplifies the management of data flow and reduces the risk of data loss.
• Multiple Power Saving Modes: Equipped with various power-saving modes to reduce power consumption, making it ideal for battery-operated portable devices.
• Industrial Temperature Range: Operates over an extended temperature range of -40°C to +95°C, suitable for harsh industrial environments.

The SC16IS752IBS is housed in a compact 32-pin HVQFN package, minimizing the footprint on the printed circuit board and making it an excellent choice for space-constrained applications. Its robust feature set and reliable performance make the NXP SC16IS752IBS an invaluable component for expanding serial communication in a multitude of embedded systems.
