Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The STM32L431VCI6 device is an ultra-low-power microcontroller based on the high-performance Arm® Cortex®-M4 32-bit RISC core that operates up to 80 MHz.The Cortex-M4 core features a single-precision floating-point unit (FPU) that supports all Arm® single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a Memory Protection Unit (MPU) for increased application security.

The STM32L431VCI6 device embeds high-speed memory (up to 256 Kbytes of Flash and 64 Kbytes of SRAM), a Quad SPI Flash interface (available in all packages), and a large number of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.

The STM32L431VCI6 devices embed multiple protection mechanisms for embedded Flash and SRAM: read protection, write protection, proprietary code read protection and firewall.

The devices provide a fast 12-bit ADC (5 Msps), two comparators, an operational amplifier, two DAC channels, an internal voltage reference buffer, a low-power RTC, a general-purpose 32-bit timer, a dedicated 16-bit PWM timer for motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers.

In addition, up to 21 capacitive sensing channels are available.

They also feature standard and advanced communication interfaces.

• 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.
