Key Features
Overview
La carte NFC Tag 5 Click Board™ est une carte complémentaire compacte qui contient un circuit intégré d'étiquette NFC compact. Cette carte comprend le M24LR64E-R, un circuit intégré d'étiquette NFC/RFID dynamique avec une EEPROM 64 Kbit à double interface de STMicroelectronics. Il comprend une interface I2C ainsi qu'une interface sans contact RF fonctionnant à 13,56 MHz, organisée en 8192 × 8 bits en mode I2C et 2048 × 32 bits en mode RF ISO 15693 et ISO 18000-3 mode 1. Le M24LR64E-R dispose également d'une sortie analogique de récupération d'énergie et d'une broche de sortie numérique configurable par l'utilisateur, utilisée comme interruption, basculant pendant l'écriture RF en cours ou le mode RF occupé. Cette carte Click board™ représente une solution idéale pour intégrer rapidement la technologie d'étiquette NFC dans toute application personnalisée telle que les équipements industriels ou médicaux, l'électronique grand public, etc.
La carte NFC Tag 5 Click Board™ est prise en charge par une bibliothèque compatible mikroSDK, comprenant des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé de la prise mikroBUS™.

How Does The Work?
The NFC Tag 5 Click Board™ is based on the the M24LR64E-R, a 64-Kbit dynamic NFC/RFID tag with password protection, energy harvesting, and RF status functions from STMicroelectronics. This highly integrated Near Field Communication tag module comes with a dual-interface electrically erasable programmable memory (EEPROM), an I2C interface alongside an RF contactless interface operating at 13.56MHz, organized as 8192×8 bits in the I2C mode and 2048×32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode.
The NFC Tag 5 Click Board™ contains the properly tuned integrated trace antenna on the PCB to power and access the device using the ISO/IEC 15693 and ISO 18000-3 mode 1 protocol. Power is transferred to the M24LR64E-R by radio frequency at 13.56MHz via coupling antennas.
As mentioned before, this Click board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz, fully adjustable through software registers. It also provides an Energy harvesting mode on the analog pin of the mikroBUS™ socket marked as VH. When the Energy harvesting mode is activated, the M24LR64E-R can output the excess energy from the RF field on the VH pin. If the RF field strength is insufficient or when the Energy harvesting mode is disabled, the VH pin goes into a high-Z state, and the Energy harvesting mode is automatically stopped.
Besides, it also features a user-configurable pin marked as BSY, routed to the AN analog pin of the mikroBUS™ socket, used either to indicate that the M24LR64E-R is executing an internal write cycle from the RF channel or that an RF command is in progress. When configured in the RF write in progress mode, the BSY pin is driven low for the entire duration of the RF internal write operation, and when configured in the RF busy mode, this pin is driven low for the whole period of the RF command progress.
The NFC Tag 5 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
