From April 25th to 28th, the 2023 China International Meter Industry Annual Conference was successfully held. At this exhibition, Wuhan Xinyuan Semiconductor brought CW32 family products to showcase the application solutions of meter products such as gas meters, water meters, electricity meters, combustible gas alarms, as well as industrial application solutions such as level switches, temperature controllers, and brushless motors to visitors in the meter industry. It attracted consulting and understanding from professional users, foreign friends, and organizers' media.

At the same time, Wuhan Xinyuan Semiconductor was also invited to attend the "2023 Digital Intelligence Four Meter Innovation Technology and Product Open Day Conference". Technical Director Zhang gave a wonderful sharing on the theme of "New Forces in Core Manufacturing - CW32 Series MCU", introducing the demand for MCU in the smart meter market, the application of CW32 in the smart meter market, and the advantages of CW32 in the smart meter market.

Mr. Zhang, Technical Director, stated that compared to other industries, the meter industry requires MCU to operate continuously and stably for a long time, usually requiring more than ten years. Therefore, the intelligent meter market has high requirements for the reliability and stability of MCU, requiring MCU to have high-level reliability indicators such as ESD and EFT, which can ensure stable operation of the entire product lifecycle. CW32 has released test results such as HBM ESD 8KV, and all ESD and Latch Up indicators have reached the highest level of international standards.

In addition, the smart meter market has extremely strict ultra-low power requirements for MCU, requiring nA level ultra-low standby power consumption, uS level high-speed wake-up, and uA/MHz level high energy efficiency ratio. The CW32L031 low-power series products support two low-power operating modes: Sleep and DeepSleep. The operating current in the lowest power mode is only 450nA, and the wake-up time from DeepSleep mode is only 4us, which can meet the needs of the meter market.

Finally, the smart meter market also has requirements for the ecological environment and service support of MCU, requiring a complete software and hardware tool chain as well as technical support. CW32 provides comprehensive research and development materials, supporting tools, supporting mainstream development environments, equipped with professional technical exchange forums, and can also effectively support meter applications.

Specifically, regarding the application in the meter market, Technical Director Zhang introduced the application of CW32 in smart water meters, smart gas meters, and smart electricity meters.

This also reflects that the low-power CW32L series has been recognized by some smart meter markets. At the same time, Wuhan Xinyuan Semiconductor will also closely follow the market demand, conduct in-depth research on user needs, and provide customers with more diverse product choices. We welcome more industry partners to negotiate cooperation.
