2.0. Features
ISO 14443 Parts 1-4 Compliant for Contactless Smart Card Interface.
ISO 18092 Compliant for Contactless Smart Card Interface.
An external antenna for PICC contactless access applications.
Supports the following Tag Types:
oMIFARE Classic. E.g. MIFARE 1K, 4K, MINI and Ultralight.
oISO14443-4 Type A and B.
oISO18092 FeliCa, NFC tag
T=CL emulation for MIFare 1K/4K PICCs
High Speed (424 kbps) Communication for PICCs
Energy saving modes for turning off the antenna field whenever the PICC is inactive,
or no PICC is found. It prevents the PICC from exposing to the field all the time.
User-Controllable Peripherals. E.g. LED.
PCSC Compliant for Contact and Contactless Interfaces.
USB V2.0 Interface. (12M bps)
Device Firmware Upgradeable through the USB Interface.

3.0. Architecture
GD32 is for main processor for communication with PC, and control the contactless chip and
peripherals. PN532 acts as a contactless chip to perform the communication between contactless
tags and GD32.
For communication architecture, the protocol between ACR122U and PC is using CCID protocol. All
the communication between PICC is PCSC Compliant.
