Evaluation and Demonstration Boards and Kits are typically supplied as free samples and used to test, prototype, and debug a product or design. The TXS0202EVM (Evaluation Module) is an example of such a board and kit, and is used to evaluate the TI TXS0202 bidirectional logic level translator.

The most common use of the TXS0202EVM is evaluation and demonstration of the TXS0202 during development. It enables engineers to develop, debug and demonstrate the logic-level translation performance of the device. The evaluation module is designed to measure the TXS0202\'s rise and fall times, as well as its immunity to de-asserted bus noise (signal bouncing). The evaluation module offers an SDI port, which allows connection to PC-based evaluation software to determine appropriate timing parameters for the logic-level translation and bus protocols used in real-world applications. Additionally, the board is also capable of running tests to veify that the logic levels switch as expected.

The TXS0202EVM kit includes the evaluation module, power supply, logic-level translator, and debugging software. It supports a wide range of voltage supply levels, from 1.2 to 5.5V and the supply pins can accommodate voltages up to 28V. The board also has a 20-pin header allowing for easy access to the device\'s I/O pins. The onboard logic-level translator can be used to evaluate the performance of the TXS0202 in a wide variety of protocols, such as SPI, I2C, and UART.

The evaluation module is designed to provide a wide range of test functionality with minimal hardware. The evaluation software allows for easily programmed, real-time analysis of the FET switching times, voltage levels, and rise and fall times. The evaluation software also enables efficient data retention and evaluation of the dynamic logic of the TXS0202 by logging the data points for each test iteration. Additionally, the evaluation software offers a graphical user interface and multiple graphs for easy test data analysis.

In conclusion, Evaluation and Demonstration Boards and Kits, such as the TXS0202EVM, are highly-beneficial tools for engineers that are developing, debugging and evaluating new products and designs. The evaluation module offers a wide range of testing capabilities with minimal hardware required, and the accompanying debugging software allows for efficient data collection and analysis.
