I. STEVAL-MKI109D: One-Stop Sensor Evaluation and AI-Enabled Platform

STEVAL-MKI109D represents ST's next-generation sensor evaluation board, designed around a core philosophy of delivering a ‘plug-and-play’ rapid evaluation experience. This allows developers to focus on application algorithm innovation rather than low-level hardware debugging.

1. Core Hardware Upgrades: The Foundation of Performance and Flexibility

This development board features comprehensive hardware enhancements. At its heart lies a high-performance STM32H5 microcontroller based on the Arm® Cortex®-M33 core, delivering ample processing power for handling high-bandwidth sensor data. For connectivity, it features a USB-C interface alongside multiple digital interfaces including I²C, I³C, SPI, and TDM, enabling flexible adaptation to sensors employing diverse communication protocols. Furthermore, its software-configurable power supply circuit allows precise sensor voltage setting within the 0V to 3.6V range, simulating real-world operating conditions while enabling online current consumption measurement. This significantly facilitates optimisation for low-power applications.

2. Deep Integration with ST MEMS Studio: Revolutionising Visual Development

Half the STEVAL-MKI109D's power stems from its deep integration with the ST MEMS Studio graphical development environment. Developers need only insert the sensor module and connect to a PC to intuitively accomplish the following within this environment:

Data Visualisation: Real-time graphical display of sensor outputs.

Parameter configuration: Rapidly adjust sensor parameters without writing low-level code.

AI functionality experience: Directly configure and utilise the MEMS sensor's embedded Machine Learning Core (MLC) and Intelligent Sensor Processing Unit (ISPU) to enable localised AI processing at the sensor level, significantly enhancing system responsiveness while reducing overall power consumption.

Power and debugging: Optimise energy efficiency and simplify debugging processes using integrated power monitoring and voltage management features.

3. Extensive Sensor Ecosystem and Broad Applications

This platform is compatible with all ST MEMS sensor adapter boards featuring DIL24 interfaces, covering a full range of products including inertial, pressure, biosensing, and microphone sensors. ST provides plug-and-play accessories such as biosensing electrodes and remote sensing extension cables, enabling rapid prototyping of concepts from wearable health devices and smart home applications to industrial inspection and automotive ADAS systems.

II. ST25R Series: NFC/RFID Evaluation Ecosystem from Short-Range Communication to Wireless Charging

ST's ST25R series NFC/RFID reader/writer chips offer a comprehensive product line spanning entry-level to automotive-grade specifications. Complete evaluation kits and software support cater to diverse requirements, from payment and access control to digital car keys.

1. Consumer and Industrial Core: ST25R300 Evaluation Solution

The ST25R300 represents the next-generation flagship chip for consumer and industrial applications. Its evaluation board highlights two breakthrough performance features:

Stable read/write in high-interference environments: Addressing challenges where antennas are often positioned behind LCD screens in POS terminals and smart devices, the ST25R300 achieves optimised performance. It maintains ultra-high receive sensitivity while boosting output power to 2.2W. Field tests demonstrate a 40-50% increase in card reading range compared to previous generations, ensuring stable and rapid transactions even in complex electromagnetic environments (e.g., EMVCo-certified).

Revolutionary Low-Power Card Detection (LPCD): Conventional LPCD modes significantly reduce detection range. Following optimisation, the ST25R300 maintains LPCD detection ranges equivalent to standard mode, enabling battery-powered devices (such as shared equipment or door locks) to deliver seamless ‘wake-on-touch’ experiences with minimal standby power consumption.

2. Automotive-grade solutions: ST25R500/501 evaluation kits

For demanding automotive applications like digital keys and in-vehicle charging, ST offers AEC-Q100-certified automotive-grade evaluation kits.

Ultimate Performance and Miniaturisation: The ST25R501 employs an ultra-compact 4mm x 4mm package, making it the industry's smallest high-performance automotive NFC reader/writer. It is ideally suited for integration into space-constrained areas like door handles or B-pillars. The ST25R500 delivers higher continuous output power.

Engineering Challenges Resolved:

Integrated dynamic output power control and active waveform shaping technology automatically compensate for antenna variations, effortlessly meeting stringent CCC (China Communications Certification) and NFC Forum testing standards. This significantly reduces certification complexity and risk for automotive customers.

3. Unified Software and Ecosystem Support

All ST25R evaluation boards benefit from ST's unified software development suite, including graphical user interface (GUI) configuration tools, extensive API libraries, RFAL (Radio Frequency Abstraction Layer) middleware for automotive applications, and digital key code templates. Furthermore, they are integrated into ST's eDesignSuite online design tool, providing resources such as PCB thermal simulation to facilitate a seamless transition from evaluation to product design.

Automotive Microcontroller and Processor Evaluation Boards

ST's SPC5 series automotive microcontroller evaluation boards provide a complete development environment supporting AUTOSAR standards, incorporating automotive communication interfaces such as CAN-FD, LIN, and Ethernet. These boards are specifically designed for functional safety requirements, compliant with ISO 26262, enabling engineers to rapidly develop automotive electronic systems meeting ASIL grade requirements.

Addressing the specific requirements of electric and hybrid vehicles, ST offers a range of power management evaluation boards, including:

Multi-channel DC-DC converter evaluation boards
