NFC 5 Click is based on the ST25R3918, a multipurpose NFC transceiver from STMicroelectronics that enables NFC reader capabilities, passive peer-to-peer functions, and NFC card emulation. This component is designed to meet the needs of Internet of Things (IoT) applications and various consumer or industrial uses, providing outstanding analog performance. The ST25R3918 chip is adept for many NFC and HF RFID tasks, including applications in consumer electronics, IoT for accessory recognition, parameter adjustments, brand security, access management, customer engagement, and more. It complies with ISO14443 and ISO15693 standards, facilitating various NFC functions such as accessory recognition, brand protection, and consumer interaction, alongside supporting NFC Forum Tag types 1, 2, 4, and 5 in reader mode.
Thanks to its noise-reduction receiver technology, the chip stands out for its excellent read range with minimal power output, even in challenging conditions. It incorporates an advanced analog front end (AFE) and a comprehensive data framing system for NFC-A/B (ISO 14443A/B) readers, offering higher bit rates, and supports NFC-V (ISO 15693) reading up to 53 kbps. Additionally, it facilitates ISO 18092 passive initiation and targeting, along with NFC-A / NFC-F card emulation, enhancing device interaction with Android™ phones and enabling the use of Apple® App Clips through simple NDEF data exchanges.
The ST25R3918 also features a low-power wake-up mode that detects cards by measuring the antenna signal's amplitude or phase, coupled with a low-power RC oscillator and wake-up timer that activates the device at set intervals to search for tags.
NFC 5 Click offers flexibility through its support for both SPI and I2C interfaces, selectable via the COMM SEL jumpers. By default, the I2C interface is active, supporting High-speed mode operation up to 3.4MHz, whereas the SPI mode accommodates clock frequencies up to 10MHz. To notify the host MCU of completed commands or external events, like the peer device field, the ST25R3918 signals an interrupt on the IRQ pin.
The ST25R3918 has separated power and logic supply pins, and thanks to two onboard jumpers, labeled VCC and VIO, this Click board™ can operate with either 3.3V or 5V power/logic voltage levels. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this 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.

We provide a library for the NFC 5 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for NFC 5 Click driver.
Key functions
nfc5_get_mifare_tag_uid
This function reads the UID of a mifare tag.
nfc5_write_reg
This function writes a desired data to the selected register.
nfc5_read_reg
This function reads a desired data from the selected register.
Example Description
This example demonstrates the use of NFC 4 Click board by reading MIFARE ISO/IEC 14443 type A tag UID.
void application_task ( void )
{
uint8_t tag_uid[ NFC5_NFCA_CASCADE_3_UID_LEN ] = { 0 };
uint8_t tag_uid_len = 0;
if ( NFC5_OK == nfc5_get_mifare_tag_uid( &nfc5, tag_uid, &tag_uid_len ) )
{
log_printf( &logger, " TAG UID: " );
for ( uint8_t cnt = 0; cnt < tag_uid_len; cnt++ )
{
log_printf( &logger, "0x%.2X ", ( uint16_t ) tag_uid[ cnt ] );
}
log_printf( &logger, "rn----------------------------------rn" );
Delay_ms( 500 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
