The MAX14783EEUA+ is a versatile, USB-powered integrated interface portfolio designed to simplify development and reduce cost in a wide range of applications, including automotive, medical, industrial, computing, and communications.

Suitable for any mobile high-speed device, the family includes 5V-powered USB 2.0 High/Full-speed Dual Channel CAN interfaces as well as USB 2.0 Full-speed devices with half-duplex UARTs, single-channel CAN, or dual-channel LIN support. All devices feature a robust Transmit Data FIFO and optional 5V or 3.3V supply so customers can easily monitor, record, and control digital signals in a variety of data-communications networks.

Application Field

The MAX14783EEUA+ is designed to be used in both mobile and stationary systems that require high-speed USB to CAN, LIN, and UART interfaces. Applications include automotive, medical, and industrial control systems, as well as communications-related fields such as GSM/GPRS and LTE. High data-transfer rate applications such as HD video streaming can also benefit from the device.

Working Principle

The MAX14783EEUA+ is built around a USB 2.0 Full-speed Low Pin Count (LPC) interface, a simple integrated circuit that provides two channels of bridging between the USB bus and two external buses. The internal logic of the MAX14783EEUA+ arbitrates and converts signals from the USB interface, allowing devices to communicate with each other as if they were directly connected. All control and configuration registers are written and read through the LPC-compatible USB interface, providing maximum flexibility and ease of use.

The voltage levels of the MAX14783EEUA+ are configurable, allowing for operation at either 5V or 3.3V. Each channel is individually adjustable, allowing for differential signaling and improved noise immunity. The system is designed to optimize power efficiency, while providing the necessary power management features.

The MAX14783EEUA+ supports a variety of baud rates and data formats, as well as multiprotocol support for UART, CAN, and LIN. It also features an advanced diagnostic and auto-baud detection system, enabling the device to accurately monitor and record the communications state of the external device.

The device has built-in safety features, including temperature, current, and voltage monitoring, as well as over-temperature management and fault detection. All internal circuitry of the MAX14783EEUA+ is ESD-protected, allowing it to be used in harsh environments.

The MAX14783EEUA+ is fully supported by Windows and Linux operating systems, and is available with a range of software tools that enable customers to easily develop and maintain communication networks.
