2.2 ATA8352 Demo Kit – Variant B

This Demo and Evaluation kit variant uses an ATSAMC21-XPRO board for the Verifier node and up to five ATAUWB-EK1 boards for the Prover node with an embedded ATSAMC21-XPRO MCU board to control the operation of the ATA8352 device. The following components are used for the Verifier and Prover nodes:

Verifier Node:

• One ATSAMC21-XPRO board
• One OLED1 Xplained Pro Extension board
• One ATA8352 Xplained Pro Extension board with ATA8352 module with V7.0 device or later
• One UWB antenna with SMA connector
• One USB cable for 5V USB supply and for connection to a PC with Microchip Studio 7

Prover Node:

• Up to 5 ATAUWB-EK1 boards with:
  • ATSAMC21 MCU
  • ATA8352 module. For more details, refer to the ATA8352 Module Application Note.
  • CAN and LIN driver IC
  • 12V supply with DC/DC converter for 5V, 3.3V and 1.25V supply
  • USB connector for 5V supply
  • MCP2221A USB COM port driver with 5V USB supply
  Note: The ATAUWB-EK1 board requires an SWD debugger (Microchip-ICE) for programming and debugging of the software application.
• Up to 5 UWB antenna with SMA connector

Each node is programmed with a demo application for the operation as a verifier in VRo mode or as a prover in PRo mode. For more details, refer to the ATA8352 Impulse-Radio Ultra Wideband (IR-UWB) Transceiver User's Guide. During the distance measurement, the applications operate at an RF frequency of 6.52 GHz with more than 540 MHz bandwidth. The default frequency range can be changed using the application’s software. With the ATA8352 Evaluation package and ATA8352 Testing packages, the other frequency ranges can be used, for example, 7.04, 7.56 and 7.987 GHz. For more details, refer to the ATA8352 Impulse-Radio Ultra-Wideband (IR-UWB) Transceiver Data Sheet.

The following figure illustrates the demo setup for the variant B. The Prover and Verifier nodes are preprogrammed with the demo application and will start once the USB power is applied.
