Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The STM32U385VGI6 is an ultra-low power microcontroller based on the Arm Cortex-M33 core launched by ST. It is mainly targeted at scenarios with strict requirements for power consumption and security, such as wearable devices, industrial sensors, and home automation.

Core configuration

The STM32U385VGI6 is based on the Arm Cortex-M33 core, with a main frequency of 96 MHz. It integrates an FPU (Floating-point Unit) and supports Trust Zone security technology.

Adopting A near-threshold design, the power consumption in operation mode is reduced by 5 times compared to the previous generation, the static current is less than 2µA, and the dynamic power efficiency reaches 117 coremark/mw.

Memory and Storage

The STM32U385VGI6 contains 256 KB of RAM and 1 MB of dual bank Flash storage space, and supports hardware encryption function.

Safety features

The STM32U385VGI6 is equipped with multiple encryption mechanisms (such as AES hardware encryption) to enhance data protection and is suitable for security-sensitive scenarios in medical and industrial fields.

Encapsulation and Scalability

The STM32U385VGI6 adopts a UFBGA100 pin package and supports communication interfaces such as USB, I2C, and SPI, making it suitable for a variety of application scenarios.

Application scenarios

The STM32U385VGI6 microcontroller is suitable for fields such as wearable devices, industrial sensors, and home automation systems that require high energy efficiency and safety guarantees. ‌

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
