The UMFT234XD-WE is an evaluation and demonstration board belonging to the FTDI Chip range of USB Interface Integrated Circuit products. In particular, the UMFT234XD-WE is an isolation interface board, designed to enable engineers and hobbyists to easily and conveniently design and evaluate MPSSE (Multi-Protocol Synchronous Serial Engine).

Application Fields

The UMFT234XD-WE board has a wide range of applications, which include embedded system interface, factory automation, asset tracking, medical devices, and many more. The board provides a high degree of flexibility by allowing engineers and hobbyists to easily evaluate and demonstrate the various serial communications protocols and interfaces, in prototype or final product designs.

Working Principle

Industrial automation, medical devices, asset tracking, etc. all require the use of serial communications protocols. The UMFT234XD-WE board provides a control window, allowing devices to interact with each other. This is done by utilising the MPSSE engine built into the FTDI chip – a powerful and highly efficient serial protocol acceleration engine. The MPSSE engine features support for a wide range of popular serial protocols, such as I2C, SPI, and UART.

The FTDI chip also contains two transceiver channels – one for the device to communicate with the host, and the other for the device to communicate with other devices. The second transceiver channel is isolated from the device, allowing for safer and more secure communication between devices. This is especially important when dealing with sensitive information, such as a person’s medical data.

The UMFT234XD-WE board also allows users to directly control the pins of the FTDI chip, through their access to the FTDI Basic registers. This provides a further layer of protection against any external interference, as the FTDI Basic registers are only accessible to the user. This gives users the ability to modify the FTDI chip to their own requirements.

The UMFT234XD-WE board also features an embedded LED status indicator, which notifies the user when the chips have been properly configured. This helps to avoid any unnecessary errors during the operation of the device.

In conclusion, the UMFT234XD-WE board provides users with the ability to easily evaluate and demonstrate the various serial communication protocols, while also ensuring secure communication between devices. The FTDI chip and MPSSE engine provide the necessary tools for engineers and hobbyists to create powerful and reliable applications, or to test and debug existing systems.
