User manual for ready-to-use evaluation kit based on universal ST25R200 NFC
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.
