Introduction – Core User Needs & Industry Context
Embedded system designers require microcontrollers with native USB support for devices like keyboards, mice, game controllers, USB-to-serial adapters, and IoT sensors. General-purpose MCUs lack optimized USB protocol processing and low-power design. USB-specific MCUs — dedicated integrated circuits with integrated USB interface control functionality — solve these challenges. They integrate CPU, memory, USB physical layer (PHY), and serial interface engine (SIE) into a single chip, supporting USB 1.1/2.0/3.0/3.1/4.0 standards with control, bulk, interrupt, and isochronous transfers. According to the latest industry analysis, the global market for USB Specific MCUs was estimated at US$ 218 million in 2025 and is projected to reach US$ 341 million by 2032, growing at a CAGR of 6.7% from 2026 to 2032. In 2024, global volume reached 15 million units.
