The evaluation board uses PN532 highly integrated contactless reader chip, which contains 80C51 microcontroller core (8051 users can not access its
programming, it is used the built-in NFC underlying communication protocol stack), integrated with 13.56MHz various active / passive contactless communication methods and protocols.
PN532 transmission module supports 6 different operating modes:
A: read-write mode, supports ISO / IEC 14443A / MIFARE? mechanism
B: reader mode ,supports FeliCa mechanisms
C: read-write mode, supports ISO / IEC 14443B mechanism
D: card operating mode, supports ISO 14443A / MIFARE? mechanism
E: card operation mode, supports FeliCa mechanism
F: ISO/IEC18092, ECM340 point to point
Based on the above advantages, PN532 evaluation board provides below hardware and software:
1, Provide NFC evaluation board. Support Host Interface: SPI interface, I2C interface and a serial UART.
2, Provide NFC WinCE systems development services.
3, PN532 evaluation board can be connected with the computer via the serial port ，and PC host computer can use LIB NFC, LIB NFC is an open source software, particularly powerful, achieve a lot NFC function. You can also use the graphical NFC debugging tools offered to carry out NFC debugging and development
4, The circuit board lead out all pins of the PN532 to facilitate the secondary development assessment, including smart MX chip interface also lead out. PCB antenna through mathematical formula, and then use the vector network analyzer for measurement, reading distance can reach the farthest 137.5px.
Application:
NFC has a wide range of applications in access control, public transportation, and mobile payment etc.
