Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Under the dual waves of the Internet of Everything and green low-carbon development, ultra-low power microcontrollers (MCUS) have become the core engines in fields such as smart wearables, industrial Internet of Things, and new energy devices. As an important partner of STMicroelectronics (ST), Shenzhen Mingjiada Electronics Co., Ltd. focuses on the STM32U3 series microcontrollers based on the Arm® Cortex®-M33 core, providing a one-stop supply service to offer the industrial chain hardware foundation that combines high performance and ultimate energy efficiency.

STM32U3: A technical paradigm of ultra-low power consumption and security

The STM32U3 series is the first ultra-low power MCU under ST to adopt near-threshold voltage technology, significantly reducing dynamic power consumption to an industry-leading 10μA/MHz. Its core architecture and performance include:

High-performance processing core: Equipped with a 96MHz Arm® Cortex®-M33 processor, it integrates a single-precision floating-point unit (FPU) and a DSP instruction set, supporting 144 DMIPS performance, catering to both complex computing and real-time control requirements.

Revolutionary energy-saving technology

Standby power consumption as low as 1.6μA (in Stop 3 mode, maintained with 8KB SRAM)

SMPS step-down converters that support dynamic voltage regulation significantly extend the lifespan of battery-powered devices.

Military-grade security architecture

Hardware-level TrustZone® isolation technology separates independent execution domains for secure and non-secure code.

It integrates an AES-256 encryption coprocessor, a true random number generator (TRNG), and a tamper-proof detection unit.

The Public Key Accelerator (PKA) optimizes the performance of encryption algorithms to meet the end-to-end encryption requirements of IoT devices.

Enrich the peripheral and development ecosystem: Accelerate product launch

The STM32U3 series significantly simplifies system design through highly integrated peripheral resources:

Enhance communication capabilities: Supports multi-protocol interfaces such as USB full-speed host/device, CAN FD, dual I3C buses (compatible with I²C), and OCTOSPI external memory interfaces, making it easy to connect sensor networks with cloud platforms.

High-precision perception system

Dual-channel 12-bit ADC (2.5Msps sampling rate) paired with hardware oversampling

Built-in operational amplifiers and low-power comparators, suitable for precise analog signal conditioning scenarios

Up to 21 capacitive sensing channels empower touch interface design.

Mingjiada's supply chain empowerment: Seamless connection from sample to mass production

Relying on its in-depth cooperation with ST's original factory, Mingjiada has established a differentiated supply system:

Original factory direct supply + safety stock: Always in stock of all models such as STM32U375KGU6 (UFQFPN32 and other packages), covering small-batch verification to million-level mass production orders.

48-hour agile delivery: Coordinated warehousing across multiple domestic locations to ensure response to urgent orders and avoid the risk of production line disruptions for customers.

Global technology response: Establish service centers in Southeast Asia and Europe to provide localized support for overseas customers.

Application scenarios: Green innovation from Industry 4.0 to consumer electronics

STM32U3, with its AEC-Q100 automotive certification (-40°C to +105°C) and safety features, has been widely applied in:

Industrial automation: Real-time motor control, predictive maintenance of sensor nodes

Intelligent healthcare: Portable monitors, low-power implantable devices

Consumer electronics: TWS headphones, smart home central control systems

Energy Management: Solar power optimizer, smart electricity meter

Conclusion: Drive Internet of Things innovation through the technology supply chain

By focusing on the STM32U3 series, Mingjiada Electronics not only provides chip hardware but also builds a full-cycle service system covering selection support, development tools, and rapid delivery.
