Power management Figure 6: Power Management The MIFARE SAM AV3 evaluation board is equipped with a mini-USB connector to power the system. The port is used only to provide for power only. The entire board can be powered by either the USB port or the 5 V line on the Arduino header.
Page 6: Figure 7: Clrc663 Communication Interface Selection
The SPI-Interface is directly connected to the Arduino header, the I²C interfaces are meant to be used by the MIFARE SAM AV3 for its X-mode. Jumper setting details can be found in the section jumper settings in this document User manual COMPANY PUBLIC Rev.

5 MIFARE SAM AV3 – Add-on Board Add-on board The MIFARE SAM AV3 itself is placed on an add-on board, to be able to easily exchange the MIFARE SAM AV3 in case it has been misconfigured. The pullups for the MCU_I²C_xxx interface, as well as the voltage level divider are placed on the add-on board.

Page 9: Figure 14: Jumper Settings Spi Or I²C Host Interface Mode
6.1.1 In case I²C is selected, the CLRC663 will be controlled by the MIFARE SAM AV3 in X- mode. The 4 jumpers need to be inserted in the 10 pin header as shown, these correspond to the ADR0 and ADR1 pins on the CLRC663 host interface in I²C configuration.
Page 10: Figure 16 Sam Av3 Vdd And Iso7816 Selection
VDD is selected on JP9, the options are permanent 3V3 or IO6 on the Arduino header. Permanent 3V3 means that the MIFARE SAM AV3 will stay in the state it is, until the whole board is power cycled. The ATR of the SAM only needs to be retrieved once.
Page 11 I²C processing clock speed: 6 MHz This reduces the I²C communication speed on the X-mode interface to ~400 kbit/s. All details about the MIFARE SAM AV3 configuration and features can be found in the respective NXP documents. User manual COMPANY PUBLIC Rev.
Page 12: Figure 17: X-Mode Configuration Example
8 Modes of Operation X-Mode The easiest way to get started with the MIFARE SAM AV3 evaluation board is to operate the MIFARE SAM AV3 in X-mode. See an example configuration below where the SAM can be accessed via the I²C1 interface from the MCU, and will communicate to the CLRC663 via its host interface, configured as I²C.
Page 13: Figure 19: Xs-Mode Configuration
In this configuration, the CLRC663 is connected on its host interface via SPI to the MCU, and on the second interface via I²C to the SAM. The MIFARE SAM AV3 is connected via I²C1 to the MCU. In this way, the MCU can control the CLRC663's LPCD procedure, and if a card is detected, the SAM can be switched on and take over the control over the CLRC663.
