User manual for ready-to-use evaluation kit based on universal ST25R200 NFC
device for contactless applications
Introduction
The STEVAL-25R200SA is a ready-to-use kit based on the ST25R200 high-performance NFC universal device for contactless
applications.
The kit allows evaluating the ST25R200 features and functionality in the reader/writer modes.
Presented in the form of a single divisible card (STEVAL-25R200A), the kit consists of:
•
•
•
The core system designed for basic evaluations of the reader performances and features composed of:
–
ST25R200 module main board that embeds the ST25R200 device and an STM32 G0 processor
–
STLink companion board that includes an ST-LINK in-circuit debugger and programmer for the STM32.
–
Main NFC antenna 20x20 mm etched on the PCB with its tuning circuit.
The complementary antennas are designed for testing various topologies that can substitute the main NFC antenna:
–
Dual antenna hub with two 12 x 12 mm tuned antennas for evaluating the ST25R200 dual antenna feature.
–
Flexible antenna board tuned for being connected to the flexible antenna delivered with the kit.
–
50-ohm antenna interface board tuned for being connected to any 50-ohm NFC antenna available on the market.
The tag boards for reader and tag system evaluation:
–
Tag 1: ST25TV board that embeds an ST25TV with its tuned 10 x 5 mm antenna
–
Tag 2: ST25TN board that embeds an ST25TN with its tuned 10 x 5 mm antenna
These eight boards are breakable for composing and evaluating various combinations.
A connector is present on all subsystems for a quick and robust connection to the system core. It is based on the ST25R200
and the STM32, which includes hardware and software tools that enable using the entire STM32 ecosystem.
This board is powered through a micro-USB connector.
Thanks to several demonstrations that can be performed, this kit helps the users develop and test their applications.
The board is configured to support ISO14443A/B, and ISO15693 communication.
The ST25R200 manages frame coding and decoding in reader mode for standard applications, such as NFC, proximity, and
vicinity HF RFID standards. It supports ISO/IEC 14443 type A/B and ISO/IEC 15693 RF communication protocols as well as the
detection, reading and writing of NFC forum type 1, 2, 4, and 5 tags.
It contains a low power wake-up system capable of detecting an approaching tag. It also contains a low power RC Oscillator
and wake-up timer to automatically wake-up the device after a selected time period and check for a tag presence.
The kit is FCC certified, with FCC ID: YCPR200AD1. It is also IC certified, with IC: 8976A-R200AD1; PMN: STEVAL-25R200A;
HVIN: STEVAL-25R200A.

STEVAL-25R200SA kit usage
2.1.1
Kit content
The kit can be divided into three segments:
1. The reader system consisting of:
–
The STLink debugger that powers and link the boards through a micro-USB connector to a computer
with a graphical user interface running. This firmware is available on ST.com.
–
The ST25R200 module that embeds an STM32 and the ST25R200.
2. The various antennas. Depending on the user application they can be connected to the reader system.
3. The tags. Available in PCB or sticker format to simulate a final application.
2.1.2
Option
You can connect a 50-Ω antenna of your desired brand and form factor. The footprint also allows connecting and
matching fully customized antennas.

Core system boards

2.2.2
STLink board
The STLink is the in-circuit debugger and programmer for the STM32G0 microcontroller located on the ST25R200
module application board. The serial wire debugging (SWD) is the bus interface for this communication. It also
provides a Virtual COM port interface allowing the host PC to communicate with the target microcontroller through
a UART.
STM32 applications use the USB full-speed interface to communicate with the STM32CubeIDE software tool or
ST25R200 GUI running on the host PC.
The 5 V supply of the USB bus powers the boards. An LDO converts this voltage down to 3.3 V to supply the
microcontroller and the ST25R200. A green LED indicates when the board is powered.
The board is breakable and can be used independently. On the back side, the PCB pad signal names are
indicated for wire connections or for a solderable system module.

ST25R200 module
2.2.3.1
Presentation
The ST25R200 module embeds the ST25R200 reader device and a STM32G0B1KEUxN processor.
The 5 V supply of a USB bus powers the boards. Usually, the board is powered by the STLink board. If the
ST25R200 module is used separately, other possibilities are offered (Table 2).
An LDO converts the voltage applied down to 3.3 V to supply the microcontroller and the ST25R200.
A connector allows to plug an antenna. Five antennas are delivered with kit, the main NFC Antenna of 20x25 mm
size etched on the PCB with its tuning circuit is delivered connected to the ST25R200 module (Table 1).
This board is breakable and can be used independently. On the back side the PCB pads signals names are
indicated for wires connections or for a solderable system module (Figure 2).
Thanks to the STM32G0 IOs modularity the pins can be used for different configurations; a pre-assignment is
proposed with associated IP functions, but alternate functions can be chosen too (Table 3).
Three bi-color LEDs are available for indicating events, by default they are assigned to the demo by the firmware.
Two footprints are provided for using the board in standalone mode, a USB and an STLink.

Flexible antenna
The flexible antenna board consists of two connectors and a PCB with the tuning circuit for the flex antenna
delivered with the STEVAL kit.
The first connector allows direct connection to the main board ST25R200 module to replace the main NFC
antenna; the second is dedicated to the flex antenna connection.
The flex antenna is delivered separately in the package and can be cut for different uses case requirements.

50-ohm antenna
The 50-ohm antenna consists of a connector and a PCB with the tuning circuit and pads for a 50-ohm antenna
NOT delivered with the STEVAL kit, but available on the market.
The connector allows a direct connection to the main board ST25R200 module to replace the main NFC antenna;
the pads are dedicated to the 50-ohm antenna connection.

Antenna tuning
Tuning compatible with all the antennas delivered imposes a tradeoff due to the presence of the EMC filter on the
main board. Optimum matching is not delivered for each antenna and manual fine tuning is required. Dedicated
tools and tuning application notes are available on ST web site.
Note:
2.5
The antenna impedance must be calculated to remain below 250mA. Normally, it should be the case for 18-20
ohm tuning.
NFC tags
The tag boards are available for reader&tag system evaluation.
The antennas delivered are very small, which can impact the reader plus tag system if the application requires a
long range. In this case, please refer to the design recommendations provided on the ST website NFC.

Tag 1: ST25TV
This board embeds a ST25TV (ST25TV02K-CAFH3 UFDFPN5) with its tuned 10 x 5mm antenna.
Two PCB pads are available for temper detect evaluation TD0 & TD1. To use them, the solder bridge SB1 must
be removed.

and on, the user is encouraged to try to correct the interference by one or more of the following measures:
•
•
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
