As the global smart IoT market has fully exploded, the demand for MCUs, an important device intelligent at the node side, has continued to rise. According to IC Insights' forecast, as the IoT continues to be hot, MCU shipments will continue to rise. Within five years Global MCU sales will grow at a compound annual growth rate of 7.2% and will exceed $ 20 billion by 2020. The domestic MCU's compound annual growth rate will reach 11.7% in the future, and the market will exceed 50 billion yuan by 2020!
However, the latest IC Insights survey report shows that due to the slowdown in the growth of the electronic technology market caused by the US-China trade war, MCU sales fell 13% annually in the first half of this year, while MCU unit shipments fell 14%. By the middle of 2019, the MCU market is becoming stable. IC Insights ’global MCU market size will shrink to US $ 16.5 billion this year, which is lower than US $ 17.6 billion in 2018. However, IC Insights predicts that the global MCU market will rebound next year.
The global MCU is sluggish, but the Chinese MCU market is very good. Due to the increasing demand for domestic replacement of MCUs in the white goods, consumer electronics, and industrial electronics sectors, the sales of local MCU manufacturers have generally skyrocketed. MCU sales in 2019 have generally increased by more than 400%! At this time, National Technology entered the MCU market, bringing more choices to this market!
