PN544

Near field communication (NFC) controller

Enabled in PCD mode for ISO/IEC 14443 Type A the PN544’s internal transmitter part is

able to drive a PCD antenna designed to communicate with ISO/IEC 14443 Type A cards

and transponders without additional active circuitry. The receiver part provides a robust

and efficient implementation of a demodulation and decoding circuitry for signals from

ISO/IEC 14443 Type A compatible cards and transponders. The digital part handles the

complete ISO/IEC 14443 Type A framing and error detection (Parity & CRC).

The PN544 supports Mifare Classic (e.g. Mifare Standard) products.

Enabled in PCD mode for FeliCa, the PN544 controller IC supports the FeliCa

communication scheme. The receiver part provides a robust and efficient implementation

of the demodulation and decoding circuitry for FeliCa coded signals. The digital part

handles the FeliCa framing and error detection like CRC. The PN544 supports contactless

communication using FeliCa Higher transfer speeds up to 424 kbit/s in both directions.

Enabled in PCD mode for ISO/IEC 14443-B, the PN544 supports all layers of the

ISO/IEC 14443-B PCD communication scheme.

Enabled in VCD mode for ISO/IEC 15693, the PN544 supports all layers of the

ISO/IEC 15693 VCD communication scheme. The PN544 supports ICODE-SLI and

ICODE-EPC from the NXP ICODE product family.

The PN544 offers the possibility to communicate directly to an NFCIP-1 device in the

NFCIP-1 mode. The NFCIP-1 mode offers different communication mode and transfer

speeds up to 424 kbit/s. The digital part handles the complete NFCIP-1 framing and error

detection. The NFC IP1 mode implementation will be in accordance with the NFC Forum

requirements.

In PICC emulation mode, the PN544 is able to answer to a PCD command either

according to the FeliCa, ISO/IEC 14443A/Mifare or to the ISO/IEC 14443B and Type B’

PICC interface scheme. The PN544 generates the digital load modulated signals and

sends the answer back to the PCD. The number of active emulated or integrated PICC

emulations is configurable via the host interface, with only one PICC active at same time.

In order to fit into power requirements of mobile platform, PN544 supports various power

modes, configurable both by hardware and software. PN544’s power consumption

behavior is fully configurable by software, but also in case of power loss PN544 is capable

of maintaining subset of communication abilities if configured in such a manner. Power

modes are described in more detail in Section 9 “Power supply” on page 18.

The use of this NXP IC according to ISO/IEC 14443B might infringe third party patent

rights. A purchaser of this NXP IC has to take care for appropriate third party patent

licenses.

Purchase of an NXP Semiconductors IC that complies with one of the NFC Standards

(ISO/IEC 18.092; ISO/IEC 21.481) does not convey an implied license under any patent

right on that standards.

A license for the portfolio of the NFC Standards patents of NXP B.V. needs to be obtained

at Via Licensing, the pool agent of the NFC Patent Pool, e-mail: info@vialicensing.com".
