In 2022, the new crown epidemic raged again, Shenzhen Huaqiangbei was closed, and Hong Kong, as an important chip trade center, diagnosed more than 6,000 people in a single day, which brought shock to my country's semiconductor industry. Internationally, with the escalation of the conflict between Russia and Ukraine, the two major Ukrainian suppliers Ingas and Cryoin, which account for nearly half of the global supply of neon gas, have ceased operations successively. The shortage of semiconductor-grade neon gas for core making is undoubtedly worse for the chip industry.

Faced with the new situation, many companies have begun to explore new directions.

※The global chip shortage affects the market supply and demand

At present, the shortage of MCUs is the most serious in the world. The delivery period in February is as long as 35.7 weeks (over 8 months). The reality is that the delivery period of 52 weeks for MCUs is quite common. The shortage of power management ICs is second only to MCUs, with lead times extending 1.5 weeks for the month. Relevant surveys show that TSMC's shipment data is not much different from the same period in 2021, and the global chip shortage may continue for 2-3 years.

– Lierda Open CPU Water Meter Solution –

At present, the intelligent remote water meter on the market is basically designed with a dual-core architecture of MCU + communication module, which is jointly responsible for internal processing and external data interaction. The Open CPU solution uses the module as the processor and carries out the overall development and design through the existing resources.

▲ Resource requirements for Open CPU water meter solution

In order to bypass the problem of "lack of cores", Lierda has developed and designed a set of Open CPU water meter solutions based on the Lierda NB860 communication module in response to the needs of various meter manufacturers, to solve the MCU price increase and shortage of goods for customers.

▲ Scheme Architecture


1. Reduce costs: save a MCU and reduce the cost of core components

2. High integration: the core components are more compact, and the product size can be directly reduced

3. Remote upgrade: application deployment is more assured, maintenance and upgrade are easier

4. Lower power consumption: remove part of the energy consumption of the MCU, and have higher interaction efficiency

Under the current semiconductor market, Lierda will continue to adhere to the road of technological self-improvement, give full play to innovation, increase investment in scientific research, and ensure the supply of production capacity and industry development in order to solve the drawbacks of frequent replacement plans for watch companies due to lack of cores. The stability of the company will wait with you for "spring flowers bloom".
