Product details

Overview

ST25RU3993-HPEV from STMicroelectronics is a high-power RAIN® (UHF) RFID reader evaluation kit built around the ST25RU3993 UHF RFID reader IC, supporting ISO/IEC 18000-63:2015 and Gen2V2 protocols, offering dual antenna ports (SMB), 30 dBm external PA output, -80 dBm RX sensitivity (ISO18046-3:2012), and frequency tuning from 840–960 MHz with 25 kHz steps - used for evaluating UHF tag read/write performance in logistics and asset tracking systems.

For engineers reviewing the ST25RU3993-HPEV datasheet, ST25RU3993-HPEV pinout, ST25RU3993-HPEV application, or ST25RU3993-HPEV equivalent, this kit provides hands-on validation of RF power control, carrier cancellation tuning, adaptive anti-collision, UHF transponder EPC read/write, and GUI-driven configuration via USB/UART bridge with STM32L476RGT6 MCU control.

Technical Context

The ST25RU3993-HPEV implements a complete UHF RFID reader system architecture integrating ST25RU3993 IC, TQP9107 power amplifier, SKY13431-374LF RF switch, MAX4003EUA power detector, and TCXO-based 20 MHz reference. It supports both internal and external PA configurations, differential RX input, and automatic carrier cancellation to improve RX sensitivity by suppressing self-interference.

It enables real-time RF parameter adjustment including TX power level (configurable), RX gain (adaptive/manual), anti-collision slot timing, and antenna port selection (ANT1/ANT2). The board operates across global UHF bands (840–960 MHz), includes LBT (Listen-Before-Talk) carrier sense, and delivers UHF tag RSSI measurement and custom TX command editing for proprietary protocol development.

Key Specifications

Parameter	Value and Actual Design Meaning
RF Frequency Range	840–960 MHz, tunable in 25 kHz steps - enables regional compliance (FCC/ETSI/China GB/T).
Max TX Power	30 dBm (external PA), 17.5 dBm (internal PA) - supports long-range far-field tag interrogation.
RX Sensitivity	-80 dBm (90% read success, one sideband, ISO18046-3:2012) - ensures reliable detection of low-power tag responses.
Antenna Ports	Two SMB (male) connectors with GUI-controlled automatic/manual switching - allows A/B antenna testing without hardware rework.
Host Interface	USB Micro-B (FT231XQ-R bridge) + UART_LOG debug channel - enables GUI operation and firmware-level diagnostics.
Control MCU	STM32L476RGT6 (Arm Cortex-M4, 64 MHz, 1 MB Flash, 128 KB RAM) - runs embedded control logic and USB stack.
Power Supply	6 V DC barrel jack (5 mm OD / 2.1 mm ID); 5 V USB bus power - separates RF and digital supply domains.

FAQ

What host software is required to operate the ST25RU3993-HPEV?

The ST25RU3993-HPEV is controlled via a dedicated graphical user interface (GUI) provided by STMicroelectronics and downloadable from www.st.com. The GUI communicates over USB/UART using the FT231XQ-R bridge chip and requires driver installation on Windows. No third-party SDK or custom firmware upload is needed for basic operation.

Does the ST25RU3993-HPEV support both FCC and ETSI regulatory bands?

Yes - the board supports full 840–960 MHz tuning with 25 kHz resolution, enabling configuration for FCC (902–928 MHz), ETSI (865–868 MHz), and China GB/T (920–925 MHz) bands. Antenna selection and TX power limits are adjustable per regional requirements through the GUI.

Can the ST25RU3993-HPEV be used with custom antennas beyond the included patch and loop types?

Yes - the two SMB (male) antenna ports accept any 50 Ω UHF antenna. Users may substitute antennas optimized for near-field, far-field, linear/circular polarization, or specific form factors. Impedance matching and VSWR verification are recommended before deployment, but no hardware modification is required.

Is external power required when using the internal PA mode?

Yes - the 6 V DC barrel jack must be connected regardless of PA mode. The board uses the 6 V input to generate regulated 3.3 V, 3.6 V, and PA-specific LDO supplies. USB power alone is insufficient to drive RF circuitry or sustain stable operation of the STM32L476RGT6 and ST25RU3993 under active RF conditions.
