NXP’s NCx3340 is an ideal solution for designers working in
automotive real-time operating system (RTOS) environments.
The NCx3340 comes with embedded NFC firmware and uses
the NFC Forum’s NCI interface to ease the NFC software
integration.
The embedded firmware reduces the BoM and enables a
smaller design because it lets the NCx3340 connect directly
to the host processor. The use of production-ready drivers
simplifies integration and reduces time-to-market, while
compliance with the NFC Forum ensures interoperability with
every NFC-enabled product on the market.
The small HVQFN40 package and low power operation make
the NCx3340 suitable for use in various automotive applications.
The integrated power management supports hard power down
mode and consumes less than 1 mW in the polling phase.
RF PROTOCOLS
The NCx3340 executes peer-to-peer mode in compliance with
the NFC Forum-defined standard NFCIP-1 and NFCIP-2. It
supports host-card emulation in accordance with ISO/IEC 14443
Type A/B, and supports all the relevant protocols for read/write
modes, including ISO/IEC 14443 Type A and B read/write up to
848 kbits/s, ISO/IEC 15693, FeliCA read/write up to 424 kbits/s,
read/write support for MIFARE cards, and all NFC Forum tag
types. The NCx3340 is also compatible with ISO/IEC 15693 to
complete the broad range of possible applications.
SUPPORT TOOLS
For a head start on design, the NCx3340 is available with
a demo kit that includes a NCx3340 demo board, LPC1769
LPCXpress host controller board, Windows
