Artery Launches AT32F406/F408 Mainstream MCU Series for Smart Control and High-Speed Data

TAIPEI, Sept. 2, 2026 /PRNewswire/ -- Artery Technology recently launched its new AT32F406/F408 mainstream microcontroller (MCU) series. Powered by the Arm® Cortex®-M4F core with a clock speed of up to 216 MHz, the new series features large memory capacity, extensive communication interfaces, and high-speed analog peripherals. It is designed for a wide range of applications, including gaming keyboards, industrial automation, smart control, USB devices, IoT, and consumer electronics.

As smart devices demand greater real-time computing performance, faster data exchange, and higher system integration, the AT32F406/F408 series builds on the AT32F402/F405 series with enhanced computing, data transmission, and control capabilities. It provides robust performance for high-speed data acquisition, real-time control, and multi-interface applications, enabling developers to build more efficient and flexible embedded systems.

High-Performance Computing and Flexible Memory for Fast Response

The AT32F406/F408 series is based on the high-performance Arm® Cortex®-M4F core running at up to 216 MHz, with DSP instructions and a floating-point unit (FPU) for enhanced computational and real-time control performance. It integrates up to 512 KB Flash and 192 KB SRAM, along with 26 KB of Bootloader system memory that can be flexibly configured for user programs or data storage, maximizing available memory and resource utilization.

The series also integrates 4 KB OTP memory for permanent storage of critical data and parameters. A QSPI interface enables external Flash or RAM expansion, further extending system memory and functionality. In addition, sLib provides protection for designated program areas, creating a secure code execution region and enhancing overall code security.

Extensive Peripheral Resources for Enhanced System Integration

The AT32F406/F408 series integrates three 12-bit high-speed ADCs with sampling rates of up to 5.33 Msps and support for external expansion. It also provides eight SPI, three I2C, six USART, and two UART interfaces, together with multiple high-performance timers and high-speed GPIOs to support diverse peripheral connectivity and high-speed data transmission requirements.

In addition, nearly all GPIOs support 5 V-tolerant inputs, reducing hardware interface constraints and simplifying the integration of sensors and peripheral modules.

Two Series Options for Diverse Application Requirements

The AT32F406 and AT32F408 share the same core architecture and development environment, allowing developers to select the most suitable device for different product requirements while maintaining flexibility for future upgrades.

AT32F406 Series: Integrates three 12-bit high-speed ADCs with sampling rates of up to 5.33 Msps and support for external expansion. With a balance of control performance and cost efficiency, the series is well suited for mainstream embedded control, industrial automation, and IoT applications.

AT32F408 Series: Building on the AT32F406, the AT32F408 further integrates USB OTG HS with a dedicated 4 KB FIFO buffer. Without requiring an external USB High-Speed PHY, it delivers high-speed USB connectivity for gaming keyboards and game controllers, enabling lower latency and faster response. Its high-speed data transmission capabilities also make it well suited for industrial data loggers, measurement equipment, medical electronics, and high-speed USB devices.

Industrial-Grade Reliability and Comprehensive Development Ecosystem

The AT32F406/F408 series supports an industrial operating temperature range of -40°C to +105°C and is available in QFN48 (6 × 6 mm) and LQFP64 (7 × 7 mm) packages, providing flexible options for compact designs and diverse application requirements.

The AT32F406/F408 series is supported by Artery's comprehensive development ecosystem, including AT32 IDE, AT32 VSCode IDE Extension, AT32 Workbench, AT32 AI Studio, AT32 development boards, AT-Link debugging and programming tools, and comprehensive technical documentation. These resources provide developers with end-to-end support from product development and debugging to validation and mass production.

Looking ahead, Artery Technology will continue to expand its AT32 MCU portfolio, extending from mainstream control to high-performance Edge AI applications. With a broader range of MCU solutions, Artery aims to empower developers to create next-generation smart control products for emerging AI, IoT, and intelligent edge device applications.

The AT32F406/F408 series is now available for sample requests and mass production.
