Artery releases new mainstream Cortex-M4F MCUs with optional high-speed USB OTG PHY
cnx-software.com/2026/09/03/…
The AT32F406 and AT32F408 are Arm Cortex-M4F MCUs running at up to 216 MHz, with the F408 adding a USB OTG High-Speed PHY. Both offer DSP instructions, integrate up to 512 KB Flash and 192 KB SRAM, and a 4 KB OTP memory for critical data and parameters. The microcontrollers also offer a QSPI interface for external Flash or RAM expansion, and a range of digital and analog peripheral interfaces.
The AT32F406/F408 are supported by Artery’s AT32 IDE, VS Code extension, Workbench, AI Studio, and AT-Link tool. Two development boards are listed in the documentation, but they don't seem to be available for sale right now.
