Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The STM32H7A3IGT6 devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 280 MHz.The Cortex®-M7 core features a floating point unit (FPU) and supports Arm® double precision (IEEE 754 compliant) and single precision data processing instructions and data types.STM32H7A3IGT6 devices support a full set of DSP instructions and a memory protection unit (MPU) for increased application security.

The STM32H7A3IGT6 devices integrate high-speed embedded memory with up to 2 megabytes of dual-bank Flash memory, approximately 1.4 megabytes of RAM (including 192KB of TCM RAM, 1.18 megabytes of user SRAM and 4KB of backup SRAM), and connections to four APB buses, three AHB buses, a 32-bit multi-AHB bus matrix and a large number of enhanced I/Os and peripherals supporting multi-layer AXI interconnects for internal and external memory access.

All devices offer two ADCs, two DACs (one dual DAC and one single DAC), two ultra-low power comparators, a low power RTC, 12 general purpose 16-bit timers, two PWM timers for motor control, three low power timers, and a true random number generator (RNG). These devices support nine digital filters for external Σ-Δ modulators (DFSDM). 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?
