Description

NFC click mikroBUS add-on board with a NFC controller from NXP PN7120 IC

Weight: 20 g

NFC Click is a compact add-on board that contains an NFC transceiver for contactless communication at 13.56MHz. This board features the PN7120, a full NFC forum-compliant controller with integrated firmware and NCI interface from NXP Semiconductors. The PN7120 utilizes an outstanding modulation and demodulation concept for different contactless communication methods and protocols as a pre-integrated feature. It is fully compliant with many Reader/Writer standards (NFCIP-1 and NFCIP-2, ISO/IEC14443, ISO/IEC 15693, ISO/IEC 18000-3, MIFARE and FeliCa specifications), alongside support for reading all NFC tag types (type 1, 2, 3, and 4). This Click board makes the perfect solution for the development of contactless NFC applications like industrial, eGov readers, payment terminals, and more.

NFC Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board comes as a fully tested product, ready to be used on a system equipped with the mikroBUS socket.

How does it work NFC Click is based on the PN7120, a full NFC forum-compliant controller with integrated firmware and NCI interface from NXP Semiconductors. The PN7120 implements the RF and all the low-level functionality, like an antenna driving and receiver circuitry, to realize an NFC Forum-compliant reader. It utilizes an outstanding modulation and demodulation concept for different contactless communication methods and protocols. The PN7120 fully complies with many Reader/Writer standards like ISO 14443A/B up to 848 kBit/s in under 25% of ASK modulation.

The NFC Click fully complies with the NFC Forum specifications, meaning it can behave as an NFC reader, a tag, or to establish a two-way connection with another NFC device. For this purpose, the NFC Click can work in several modes. In card emulation mode, it behaves like a smart card or a tag. It does not initiate communication; it only responds to an NFC reader. The Read/Write mode makes the NFC Click behave as an NFC reader, where it can communicate with a passive tag, smart card, or an NFC device that operates in a card emulation mode. Peer-to-Peer mode establishes a two-way communication channel between a pair of NFC-enabled devices.

The NFC Click uses a standard 2-Wire I2C interface to communicate with the host MCU and supports standard mode (100MHz), fast mode (400KHz), and high-speed mode (3.4MHz). The I2C address can be selected via the ADDR SEL jumper with 0 set by default. The PN7120 has two types of integrated memory: RAM and EEPROM. Internal registers of the PN7120 store configuration data, while the RF configuration for dedicated RF protocols is defined by EEPROM data, copied by a command issued from the host MCU. This allows users to achieve maximum RF performance from a given antenna design.

In addition to the I2C interface signals, this board uses several other signals from the mikroBUS socket. The reset pin routed on the RST pin of the mikroBUS socket provides the general reset ability, while the IRT pin of the mikroBUS socket represents an interrupt request to inform the host controller of various events.

This Click board can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
