Evaluation and Demonstration Boards and Kits

Evaluation and demonstration boards and kits are essential tools for rapidly designing and testing products, which can help reduce development costs and time-to-market. They are used in many applications from industrial automation to medical sensing, and come in a variety of shapes and sizes depending on their functionality. One of the more ubiquitous boards is the ATMXT449TDAT-I2C-PCB.

Application Field

The ATMXT449TDAT-I2C-PCB is a compact and highly flexible barebone printed circuit board designed for the evaluation of Atmel\'s I2C transceivers. This board makes it easy to connect to C90 or RN88 design projects and includes a set of solderless termination points to simplify the process. The board also includes a set of LEDs for displaying device status and to enable interactive applications. It is typically used in portable devices as it is designed to be easily integrated into any design.

The ATMXT449TDAT-I2C-PCB board is easy to use and is praised for its low power consumption and fast switching times. As mentioned previously, the board is suitable for a variety of applications such as, but not limited to, industrial automation, RFID tracking, and medical sensing. Moreover, the board eliminates the need for extra hardware when integrating Atmel’s transceivers, making it the ideal choice for prototyping.

Working Principle

The Atmel ATMXT449TDAT-I2C-PCB works by connecting to a set of five essential AC bus signals, including a clock, a reset signal, and three data signals (SCL, SDA, and VDD). The board can be connected to a microcontroller or a C90/RN88 design project. When the reset signal is triggered the board automatically configures itself as an I2C master and begins transmitting data. It takes no more than two clock cycles to configure itself. Once it has been set up, the board will start sending out data in byte chunks.

The board works in ‘master send’ and ‘slave receive’ mode, meaning that data transmission is determined and controlled by the master device. A start condition initializes the bus and data is sent in 8-bit packets as master device sends out bytes, while the slave device responds when data is pending. Once acknowledgement is received, the transmission is completed and the bus is ready to send the next byte.

The board is powered by a 3.3V power source, which is required for the I2C logic level conversion. It features a low power consumption, with a typical current draw of 10 mA. Additionally, the board is capable of operating at data transfer speeds up to 10 Mbps.

Conclusion

The Atmel ATMXT449TDAT-I2C-PCB is a great tool when it comes to evaluating and testing Atmel’s I2C transceivers. This board is designed to be easily integrated into any design and is suitable for a variety of applications including industrial automation, RFID tracking, and medical sensing. The board features a low power consumption and is capable of operating at data transfer speeds up to 10 Mbps. Thanks to its efficiency and versatility, this board is the ideal choice for prototyping.
