Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The R7FA4L1BD4CNE is a low power 2-bit microcontroller (MCU) based on a TrustZone® -enabled Arm® Cortex®-M33 (CM33) core, which achieves an ideal balance of low operating voltage, low power and high performance. The operating voltage of RA4L1 is as low as 1.6V, and the standby current is as low as 1.65µ A. It also features multiple low-power functions, allowing users to dynamically optimize power consumption/performance according to application requirements.

The R7FA4L1BD4CNE MCU features low power consumption, such as a segment code LCD display driver and an advanced security engine, as well as RTC, ADC and timer. This MCU integrates communication interfaces such as CAN FD, USB 2.0FS (no external crystal oscillator required), I2C/I3C, and low-power UART. Therefore, the R7FA4L1BD4CNE is highly suitable for industrial automation, home appliances, smart home, consumer goods, building/home automation, and medical/healthcare applications.

• 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.
