Artery AT32 MCU Family Overview: AT32F1, AT32F4 and AT32L0 Selection Map

The 32-bit microcontroller market is no longer a single-vendor story. Designers who once reached straight for one familiar part now qualify a short list of Cortex-M suppliers so that supply and price do not dictate their roadmap. Artery (雅特力) and its AT32 family are a regular name on that list — Cortex-M cores, a broad peripheral set, and aggressive price-performance. This guide maps the AT32 family so you can see where each line fits, and points to the parts we actually stock.

1. The AT32 family at a glance

Artery builds AT32 around three Cortex-M tiers, plus feature-focused sub-lines.

• AT32F4 — Cortex-M4 with FPU. The performance tier: higher clock, DSP-friendly, more memory and advanced timers for motor control and industrial use.
• AT32F1 — Cortex-M3. The mainstream workhorse, the natural class for an STM32F103 replacement and general control tasks.
• AT32L0 — Cortex-M0+, low power. For battery-powered and always-on sensing where current budget dominates.

2. The part we stock

We currently carry the AT32F403ACGT7, offered as an STM32F103C8T6 alternative. It sits in the high-performance AT32F4 tier, so it is a sensible anchor when you need more headroom than an F103-class device but want to stay on a Cortex-M4 core.

3. How to place AT32 in your short list

• Decide the core and clock you actually need — M0+ for low power, M3 for mainstream, M4/FPU for DSP and higher speed.
• Confirm the package and pin count against your board before evaluating firmware.
• Treat an AT32 part as a qualified alternative to STM32: prototype, validate clock tree, Flash timing and peripherals, then scale.
• Where the exact AT32 sub-line is not in stock with us, compare against the in-stock STM32 and Chinese-alternative references we list below.

Frequently asked questions

What is the Artery AT32 family?

AT32 is the 32-bit microcontroller family from Artery (雅特力), built on Arm Cortex-M cores. The mainstream lines cover Cortex-M0+, Cortex-M3 and Cortex-M4, with the higher-end AT32F4 parts adding an FPU and running at speeds well above the typical mainstream F103-class device. They are aimed at cost-sensitive but performance-hungry applications.

Are AT32 parts a drop-in for STM32?

In many packages the AT32 pinout and peripheral set broadly follow the STM32 layout, and the part we stock is offered specifically as an STM32F103C8T6 alternative. Even so, you must verify the package, clock tree, Flash timing and peripheral behaviour on the bench before committing to volume — treat it as a qualified alternative, not an assumption.

Which AT32 line should I start with?

Start from the core and speed you need: AT32F1 (Cortex-M3) for mainstream control, AT32F4 (Cortex-M4, FPU) for signal processing and higher clock, AT32L0 (Cortex-M0+, low power) for battery and always-on designs. Match the line to the job, then narrow to package and memory.
