Energy harvesting with ST25DV-I2C series Dynamic NFC Tags
Introduction
The ST25DV-I2C series Dynamic NFC Tags offer the possibility of harvesting energy from an external RF field, and to delivery it onto their V_EH output pin. The non-regulated DC voltage on V_EH is generated by means of RF signal rectification. This function is mainly intended to supply very low power applications. The purpose of this document is to show how to use the ST25DV-I2C energy harvesting feature in an ESL application based on the ST25DV-I2C-04K in combination with an STM32L476 MCU. Additional details can be found in the ST25DV-I2C datasheets and in application note AN4913, available on www.st.com.

2.1
Benefits
Upon application of an RF field to the antenna of an ST25DV-I2C device plugged on a Discovery_ANT_Cxx board, the chip transforms the inducted energy into electrical current to supply the tag IC and the MCU.
The components can then operate as long as the RF field is present and strong enough to supply them. ST25DVxxx devices offer the possibility to automatically activate energy harvesting after boot, when entering an RF field able to automatically power the application.
2.2
2.2.1
2.2.2
Usage limitations
Target antenna size
Antenna design has to be studied carefully to ensure optimum values.
As the ST25DV-I2C is compliant with NCF Type 5 and ISO/IEC 15693 specifications, the standardized large class-1 antenna provides the best performance. It is recommended to use the available card (ST25DV_Discovery_ANT_C1) to start trials. Then an antenna perfectly turned for the custom application (number of turns, capacitances, resonance frequency) can provide more energy.
Initiator RF electromagnetic field
In an NFC exchange the initiator dialogs with the target. In this application, the target is the ST25DVI2C-04K tag and the initiator can be an RFID reader or a smartphone.
The initiator creates an inductive coupling between two loop antennas. The initiator antenna size, the antenna position, the distance between the devices are the key factors that influence the energy provided.
The ST25DV-I2C will deliver enough current if the electromagnetic field is strong enough. When the initiator is a smart phone, depending on the embedded NFC controller solution and the other mentioned parameters the available energy can be insufficient to operate the MCU.

Introduction
To verify the ST25DV-I2C energy harvesting capability a set-up based on standard NFC STMicroelectronics cards has been prepared. The ST25DV DISCOVERY MBOARD is associated with the ST25DV_Discovery_ANT_C1. On top of these two boards, an Epaper daughter card had been designed.
The solution proposed is the simplest possible one, with the lowest BOM cost. It is intended as a project guideline, from this base the final customer can easily improve it to address the target application.
3.2
ST25 discovery board
The MB1396 (ST25_Discovery_Mboard) is designed to help the user explore the features of the ST25DV-I2C-04K product with the support of the STM32 Nucleo ecosystem. This motherboard uses a 32-bit Arm®(a) Cortex®-M4 CPU with FPU high-performance microcontroller.
The MB1396 is a ready-to-use printed circuit board (PBC). In this version it includes:
· an STM32L476GT6 LQFP100 32-bit microcontroller with 1 Mbyte of Flash memory and 192 + 4 Kbytes of SRAM
· a User push button · a Reset button · a joystick · an on-board ST link for microcontroller firmware upgrade and debug · an ST-LINK mini USB

Setup
AN5233
The 2.13" active area contains 122x250 pixels, black and white color. · A connector makes it possible to power the DB, the link to an SPI and the control
signals coming from the motherboard. · A tank capacitor stores the necessary energy for a complete refresh of the display. No
another added circuitry is needed, the BOM corresponds to the manufacturer recommendations.

Operation
Operation
4.1
Start-up sequence
Without Epaper the STM32L476 operates immediately, if the current supplied by the ST25DV-I2C is higher than 2 mA.
If the Epaper daughter board is connected the STM32L476 power-on is delayed due to the capacitor added on the power line. Depending on the initiator performances, the first the boot time can be longer than 20 s.
4.2
Epaper limitation
During a refresh sequence, the Epaper requires a large amount of energy, and, without a buffer, the system powered only by harvesting cannot deliver it.
In the described setup the current storage is available in the tank capacitor. Its availability depends upon the harvested energy, with the limitations described in Section 2.2.
