Single-chip microcontrollers for embedded control and computing functions are ubiquitous and continue to be designed into more systems. MCU sales rebounded with a 27% increase in 2021 to a record-high $20.2 billion. The 2021 surge was the highest percentage growth in MCUs since 2000. The average selling price (ASP) for MCUs climbed 12% in 2021—the highest annual increase since the mid-1990s.
In the strong MCU recovery last year, the sales rankings of the five largest microcontroller suppliers remained unchanged from 2020, according to IC Insights’ new second-quarter update of its 2022 McClean Report service.
The five biggest MCU suppliers are significantly larger than the rest of the top 10 in microcontrollers, according to the update report. For instance, the second half of the top 10 (Texas Instruments, Nuvoton, Rohm, Samsung, and Toshiba) accounted for $2.3 billion in MCU sales last year, or 11.4% of the market total. Outside the top 10, MCU suppliers had just 6.5% market share in 2021.
