Microcontroller (MCU)

A microcontroller unit is a semiconductor chip that performs arithmetic processing. It is more suitable for performing basic operations than CPUs that perform the same general-purpose calculations. One of the reasons for the semiconductor shortage is that supply could not keep up with the rapid recovery in demand for microcontrollers in 2021 due to the global recession.

🟦 Microcomputer market concentrated among top companies

The top five microcontroller companies accounted for 82.1% of the global market in 2021. This percentage is larger than 72.2% in 2016. Due to major acquisitions and mergers since 2016. Furthermore, the total sales of the Top 10 are 95.5% of the total market, making the market oligopolistic.
