Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The R7FA4M3AD3CFB is a 32-bit microcontroller (MCU) product group using the high-performance Arm® Cortex®-M33 core with TrustZone support. Used in conjunction with the on-chip Secure Crypto Engine (SCE), the RA4M3 enables secure chip functionality. 

The RA4M3 is based on a highly efficient 40nm process and is supported by the open and flexible ecosystem concept of the Flexible Configuration Package (FSP), which is built on FREERTOS and can be extended to use other real-time operating systems (RTOS) and middleware.

 The RA4M3 is suited to the needs of IoT applications such as diverse communication capabilities, future-proof security features, large embedded RAM and low operating power consumption down to 119µA/MHz when running CoreMark® algorithms from flash memory.

• 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?
