I. Introduction
DFCN-4 is a kind of NFC (Near Field Communication) module that could be embedded in one IT
system by simply connecting the module through I2C interface and start developing his application
software.
II. DESIGN REFERENCE
DFCN-4 build a contactless front-end towards contactless applications available on existing system.
Integrated MCU is decoupling the host controller from the timing constrains of RF communication and
allowing autonomous operation, it provides flexible and integrated power management unit for RF
front-end.
DFCN-4 reference design module consists of the following:
• Reference Design:
When the user wishes to incorporate the DFCN-4 to their device, it is strongly recommended that this
reference design is copied “as is” in the final application board to guarantee optimum performance,
regulatory compliance and lowest development time and design effort.
• MCU FPC/FFC Connector:
Allow user to connect the DFCN-4 module to the host board via FPC/FFC connector.
• Antenna Connector:
Connected to FPC antenna, please note that matching circuitry should designed on antenna.

III. Hardware Block Diagram
DFCN-4 is a full feature NFC module and compliant with NFC standards (NFC Forum, EMVCo,
ETSI/SCP). DFCN-4 has an optimized architecture for low-power consumption in different
operation modes. The RF contactless front-end is supporting various transmission modes according
to NFCIP-1, NFCIP-2, ISO/IEC14443, ISO/IEC 15693, ISO-14443, MIFARE, and FeliCa
specifications. The major internal components are illustrated in Figure 1-1.
