Introducing the Artery AT32F406 and AT32F408 Cortex-M4F Microcontrollers

New High-Performance MCUs from Artery Technology

Artery Technology has launched the AT32F406 and AT32F408 microcontrollers, both based on the Arm Cortex-M4F architecture, operating at speeds of up to 216 MHz. The AT32F408 model includes an optional high-speed USB OTG PHY, making it particularly suitable for applications in industrial automation, IoT, and gaming peripherals.

These microcontrollers are equipped with a floating-point unit (FPU) and support DSP instructions, providing advanced processing capabilities. They feature up to 512 KB of Flash memory, 192 KB of SRAM, and a 4 KB one-time programmable (OTP) memory for critical data storage. Additionally, both models support a QSPI interface for external memory expansion and offer a variety of digital and analog peripheral interfaces.
