2. Hardware overview of the PNEV7462B board
2.1 PNEV7462B concept
The basic concept of the PNEV7462B board is to enable hardware and software
evaluation of typical PN7462 family design and to support prototyping own antenna
circuitry. The supporting NFC Cockpit tool enables antenna tuning, DPC calibration and
the related TX and RX optimization in run time.
After successful optimization, register settings can be stored in the PN7462AU EEPROM
as well as saved in configuration file and used as input in design time.
PN7462AU FW and SW Examples available on the product page, ranging from POS
demo, contact and contactless CCID reader, P2P application, NFC forum related
examples, are customized primarily for PNEV7462B/C board and supported by
MCUXpresso, Keil or IAR development tools.
2.2 PNEV7462B board
Fig 4. PNEV7462B board
The board consists of the following blocks:
(1) PN7462AU circuitry with reset and download pushbuttons,
(2) External power supply connector (5.5/2.1 socket) and power supply selector,
(3) LDO regulator circuit for 3.3V and 5V
(4) LPCXpresso m-bed expansion circuit
(5) TDA8026 multiple smart card interface circuit
(6) Antenna coil and related matching circuit (marked in green and orange)
(7) Smart card socket (main slot on bottom PCB layer) and SIM size slots on top layer
(8) 65x65mm antenna coil
(9) 10-pin Cortex debug connector
(10) 26-pin shroud GPIO header and USB micro B female connector

2.2.4 Smartcard interface
The PN7462AU integrates contact interface to enable communication with ISO7816 and
EMVCo contact smart cards, without the need for an external contact front end. It offers a
high level of security for the cards by performing current limitation, short-circuit detection,
ESD protection as well as supply supervision. Card slot/contactor is located on the board
bottom layer.
(1) Default setting for present pin (K1) is low active
Fig 7. PNEV7462B contact slot interface
2.2.5 TDA SAM extension interfaces
The PN7462AU can handle more than one smart card by controlling an extra contact
interface TDA8026 product from NXP. In this use case, the PN7462AU is the main
controller for the electrical and protocol part for the main card slot, while the secondary
slots are electrically controlled by an extra contact front-end interface (TDA), the
PN7462AU being the protocol controller for these extra slots. TDA8026 I2C port is
connected to the PN7462 I2CM to enable IC configuration.
In this case, several smart cards can be activated at the same time, but the
communication with each smart card has to go sequentially: it is not possible to
communicate with two smart cards at the same time as there is only one protocol control
block for all cards.
TDA8026 is required to handle the smart card electrical interface. The connection
between the PN7462AU and the TDA is composed of 2 channels:
- The host interface control, where the PN7462AU is the master, controlling the
TDA behavior: card activation, deactivation, TDA configuration (voltage level,
clock division, slew rates…)
- The ISO7816 link: the PN7462AU handles the ISO7816 communication protocol
and uses the TDA as a level shifter for the clock and I/O signals.
