UMFT4222EV-D is a device from NXP Semiconductors created to allow people to evaluate and demonstrate the range of applications possible with the EasyDMA peripheral of the Kinetis range of MCUs. It is a type of Evaluation and Demonstration Board and Kit that comes with on-board applications that demonstrate how to use EasyDMA in a variety of scenarios. In addition to the board and kit, it also comes with an instruction manual providing step-by-step guidance on how to complete the various tasks.

The UMFT4222EV-D board consists of a main board and one expansion board. The main board is designed to host the two Kinetis MCUs and the EasyDMA peripheral. It includes a USB Debug Interface, Ethernet and USB OTG interface. The expansion board comes with a range of additional peripherals, including an SPI, I2C and UART interface. By using the available expansion headers on the board, users can easily connect additional sensors and modules.

The EasyDMA peripheral is at the heart of the UMFT4222EV-D Kit. It is a hardware-based block-transfer engine that allows users to transfer data from one peripheral to another without needing to manually set up each transfer. It uses a DMA descriptor to control the data being transferred, and can transfer data with only a few cycles of instruction. This makes it a great choice for applications that may need to move a large amount of data very quickly, such as image or video processing.

The UMFT4222EV-D Kit contains a range of application examples which demonstrate how the EasyDMA peripheral can be used in a variety of scenarios. The applications include a UART application which shows how to use the EasyDMA peripheral to transfer data from an external UART device to internal memory, and a SIMPLE SPI application which demonstrates how to use the EasyDMA primitives to move data between an external SPI device and internal memory. There are also a number of other examples included which demonstrate the flexibility of the EasyDMA peripheral when used in conjunction with the other peripherals on the board.

The UMFT4222EV-D makes it easy for users to evaluate the EasyDMA peripheral and evaluate the range of applications possible with the Kinetis range of MCUs. It bundles everything that users need in order to evaluate the EasyDMA peripheral and the other peripherals on the board, in a single package, and provides a full suite of application examples to get users started. It is a great way to evaluate the capabilities of the Kinetis range, and to develop applications which need to transfer data quickly and reliably.
