简单介绍
POS机非接触式芯片PN512 is the most broadly adopted NFC frontend - powering more than 10 billion NFC transactions per year. It is a highly integrated NFC frontend for co ntactless communication at 13.56MHz. This NFC frontendutilizes an outst anding modulation and demodula tion concept completely integrated for different kinds of contactl ess communication methods and protocols at 13.56M

的详细介绍

POS机非接触式芯片

Enabled in Reader/Writer mode for ISO
/IEC14443A/MIFARE, the PN512¡¯s internal
transmitter part is able to drive a reader/writer antenna designed to communicate with
ISO/IEC14443A/ MIFARE cards and transponders
without additional active circuitry. The
receiver part provides a robust and effici
ent implementation of a demodulation and
decoding circuitry for signals from ISO/IEC14443A/MIFARE

compatible cards and
transponders. The digital part handles the complete ISO/IEC14443A framing and error
detection (Parity and CRC).
Enabled in Reader/Writer mode for FeliCa,
the PN512 NFC frontendsupports the FeliCa
communication scheme. The receiver part provides a robust and efficient implementation
of the demodulation and decod
ing circuitry for FeliCa coded signals. The digital part
handles the FeliCa framing and
error detection like CRC. The PN512 supports contactless
communication using FeliCa Higher
 transfer speeds up to 424
kbit/s in both directions.
The PN512 supports all layers of the ISO/IEC14443B reader/writer communication
scheme, given correct implementation of ad
ditional components, like oscillator, power
supply, coil etc. and provided that standardized protocols, e.g. like ISO/IEC14443-4
and/or ISO/IEC14443B anticollisio
n are correctly implemented.
In Card Operation mode, the PN512 NFC frontend is able to answer to a reader/writer
command either according to the FeliCa or
 ISO/IEC14443A/MIFARE card interface
scheme. The PN512 generates the digital load modulated signals and in addition with an
external circuit the answer can be sent back to the reader/writer. A complete card
functionality is only possible in combination with a secure IC using the S
2
C interface.
