The evaluation board can be fully powered with the 5 V line from this header. 3V3 is directly generated on board out of this 5 V line. The header also uses the SPI interface, which can be connected to the CLRC663 host interface for direct communication. For SAM communication, the user can choose between 2 IC interfaces: The default one on IOH1 (called IC1), as well as an alternative pinning on AD1 (called IC2). IO4 and IO5 are used for the CLRC663 PDOWN and IRQ, and IO6 can be jumpered to provide the MIFARE SAM AV3 VDD. Figure 5: Arduino header pin assignment 4 Schematics 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. The power LED signalizes 3.3V power availability.

The digital communication interface (SPI, and IC ) from MCU to the CLRC663 can be selected via jumpers. The SPI-Interface is directly connected to the Arduino header, the IC interfaces are meant to be used by the MIFARE SAM AV3 for its X-mode.

The pullups for the MCU_IC_xxx interface, as well as the voltage level divider are placed on the add-on board. Figure 10: MIFARE SAM AV3 Add-on board The MIFARE SAM AV3 can be accessed by either its IC_Slave (MCU_IC_xxx) interface from the host MCU, or the ISO7816 interface via CN5. This header is pin compatible to the GMMC ISO7816 to SIM SAM Smart Card adapter.

GREEN: Configuration of RC663 interfaces YELLOW: MCU board IC interface selection RED: MIFARE SAM AV3 configuration CLRC663 Interface Mode The CLRC663 NFC reader frontend IC offers a Host and a SAM interface. The HOST communication interface can be configured to SPI or IC by configuring the CLRC663 IFSEL 0/1 pins via jumper settings as shown in below. Figure 13: Jumper locations for Host interface selection Rev. 1.0 19-JAN-2022 8 User manual COMPANY PUBLIC Information provided in this document is subject to legal disclaimers GMMC GmbH. 2020. All rights reserved. User Manual MIFARE SAM AV3 Evaluation Board Figure 14: Jumper settings SPI or IC Host interface mode SPI 6.1.1 IC For SPI communication between MCU and CLRC663 the 4 jumpers on the 10 pin header need to be positioned as shown. This setting is intended to use the MIFARE SAM AV3 in S-mode, or in an S/X mixed mode. At this point, the MCU can already control the CLRC663 via SPI. In case IC 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 IC configuration. Now the host interface of the CLRC663 is configured as IC and both ADR pins are pulled to low. The MIFARE SAM AV3 Master IC interface (SAM_IC_xxx) can be routed to the host interface of the CLRC663. This is done with JP1 and JP2. 6.1.2 CLRC663 SAM IC Interface The CLRC663 SAM interface is a dedicated second interface for MIFARE SAM X-mode operation. As this interface is switched off per default, the IC signal from the MIFARE SAM AV3 needs to be set routed to interface 2 on JP1 and JP2. Figure 15: Selection of CLRC663 SAM interface If this interface is already activated by setting the corresponding bits in the HostCtl register of the CLRC663, the above setting is sufficient to communicate between CLRC663 and the MIFARE SAM AV3. If not, then an additional SPI connection for the MCU to the CLRC663 is needed, to activate the SAM interface.

Rev. 1.0 19-JAN-2022 9 MCU Interface Selection User Manual MIFARE SAM AV3 Evaluation Board The connection between the MIFARE SAM AV3 and the MCU is done by either of the 2 supported IC interface locations on the Arduino R3 header. The selection is done by JP3 and JP4, which are placed on the corresponding pins. MIFARE SAM AV3 host interface and VDD selection The MIFARE SAM AV3 evaluation board offers two options to interface with the MIFARE SAM AV3:

IC and ISO7816. IC was explained earlier in this document. For ISO7816 communication to supply and configure VDD of the MIFARE SAM AV3. 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. Using IO6 as VDD gives the user the possibility to only power cycle the MIFARE SAM AV3, therefore having the option of a reset, without resetting the MCU. In case a user wants to access the MIFARE SAM AV3 via the ISO7816 Smartcard interface, a Jumper needs to be placed on the ISO7816 header as shown and it is important that in this case, the VDD selection jumper needs to be removed (set to inactive position as shown), as the MIFARE SAM AV3 VDD needs to be controlled by the ISO7816 interface.

Rev. 1.0 19-JAN-2022 10 User Manual MIFARE SAM AV3 Evaluation Board 7 MIFARE SAM AV3 required default configuration changes To ensure backwards compatibility to the SAM AV2 the default configuration is set for the NXP frontend reader PN523 IC for X-mode communication. Along with this, the IC processing clock speed needs to be adjusted as well as this is set to IC fast mode (12 MHz processing clock speed) and needs to be reduced for operating the CLRC663. This needs to be changed using the SAM SetConfig command once. The command looks like the following:

Command: 80 3C 01 00 01 03 Set Configuration for reader frontend selection Value Meaning 0x80 0x3C 0x01 0x00 0x01 0x03 0x80 0x3C 0x02 0x00 0x01 0x06 Byte CLA INS P1 P2 Le INF Byte CLA INS P1 P2 Le INF Command: 80 3C 02 00 01 06 SAM_SetConfiguration for IC processing clock speed Value Meaning Class RFU Class RFU Instruction: SAM SetConfiguration Reader IC configuration Length of subsequent data field X-mode frontend CLRC663 Instruction: SAM SetConfiguration IC processing clock speed Length of subsequent data field IC processing clock speed: 6 MHz This reduces the IC 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.

Rev. 1.0 19-JAN-2022 11 X-Mode S-Mode 8 Modes of Operation User Manual MIFARE SAM AV3 Evaluation Board 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 IC1 interface from the MCU, and will communicate to the CLRC663 via its host interface, configured as IC. The SAM VDD in below example is connected to IO6. Figure 17: X-mode configuration example In this S-mode configuration, the MIFARE SAM AV3 is not connected to the CLRC663. The host MCU controls the CLRC663 via the SPI interface, and the MIFARE SAM AV3 via IC1. Figure 18: S-mode configuration example User manual COMPANY PUBLIC Information provided in this document is subject to legal disclaimers GMMC GmbH. 2020. All rights reserved. Rev. 1.0 19-JAN-2022 12 XS - Mode User Manual MIFARE SAM AV3 Evaluation Board 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 IC to the SAM. The MIFARE SAM AV3 is connected via IC1 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. ISO7816 Interface Figure 20: ISO7816 Mode In this configuration, the MIFARE SAM AV3 is controlled via the ISO7816 Interface which is available on the 16-pin header CN5. The pinning is compatible to the GMMC ISO7816 to SIM SAM Adapter which also can be used stand-alone in case the SIM sized SAM is used.
