Contactless
Automotive Reader IC
NCx3320

Automotive NFC Frontend IC
Optimized for Secure Car AccessAs a member of NXP®’s high-performance reader IC family, NCx3320 combines highRF output power with robust multiple protocol support. High integration and a small
footprint make it ideal for small form-factor car door handles.

KEY FEATURES	
Fully ISO/IEC 14443 A & B, ISO/IEC 15693 andFeliCa compliant
 ISO/NFC 18092 NFC-IP1 peer-to-peer support(initiator mode) RF driver supply voltage 3 V - 5.5 V with max
current of 350 mA Compact HVQFN32 package (5 x 5 mm) withwettable flanks
 Low Power Card Detection
 512 Byte FIFO Fast card detection with minimum power consumption
 Stores application specific configuration
 Communication with mobile NFC devices in reader/writeror peer-to-peer initiator mode Supplied with generic software library easily portable
across different MCUs
KEY APPLICATIONS Secure car access Fleet management
 Car sharing
 Center stack reader for personalization

 High baud rates (up to 848 kbits)
 8 KB EEPROM
KEY BENEFITS	High-output power RF front-end IC in small footprint Maximum reading distance combined with highoperating stability
 Supports all relevant contactless protocols
 Full compatibility with NXP smart card, smart tags
and label ICs
 Capable of handling long APDUsThe NCx3320 combines uniquely high RF output powerwith a very small HVQFN package to ensure large andreliable reading distances with NFC-enabled smart phones
and smart cards.

Its unique combination of features,
paired with robustness and quality,
creates a benchmark for the automotiveindustry, where applications require long
lifetimes paired with energy efficiency.
The NCx3320 makes it possible to create
secure solutions with NXP’s MIFARE®
products. Implementation of the initiatormode of P2P communication enables
full support of NFC-based use cases in
an automotive environment. To support
mobile phones and the emerging useof credentials in different form factors
and protocols, the device also integrates
a large internal EEPROM for fast andflexible configuration of register settings.
