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

(initiator mode)
RF driver supply voltage 3 V - 5.5 V with max
current of 350 mA
Compact HVQFN32 package (5 x 5 mm) with
wettable flanks
Low Power Card Detection
512 Byte FIFO
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 high
operating stability
Supports all relevant contactless protocols
Full compatibility with NXP smart card, smart tags
and label ICs
Capable of handling long APDUs
Fast card detection with minimum power consumption
Stores application specific configuration
Communication with mobile NFC devices in reader/writer
or 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
The NCx3320 combines uniquely high RF output power
with a very small HVQFN package to ensure large and
reliable 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 automotive
industry, 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 initiator
mode of P2P communication enables
full support of NFC-based use cases in
an automotive environment. To support
mobile phones and the emerging use
of credentials in different form factors
and protocols, the device also integrates
a large internal EEPROM for fast and
flexible configuration of register settings.
