Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MKM33Z64ACLL5 microcontrollers are precision metering MCUs with segmented LCDs, based on the Arm® Cortex®-M0+ core. These MCUs provide a low-cost, highly integrated solution for single-chip single-phase, two-phase, and three-phase meters requiring powerful 32-bit processing, precision analogue, security, and HMI functionality.The MKM33Z64ACLL5 provides security through timestamping for active and passive tamper detection, and also supports a high-precision internal voltage reference with low temperature drift. These MCUs come with a comprehensive support suite, including reference designs. Typical applications include power meters, industrial measurement and sensing, and flow meters (e.g., heat, water, and natural gas).

Applications
• Electricity meters
• Flow meters (e.g. heat, water and gas)
• Industrial measurement and sensing
• EV chargers

• 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.
