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.
