Choosing a microcontroller is only half the job; securing it through a volatile market is the other half. For a Cortex-M design, the smart move is to qualify a multi-source short list so that allocation on one vendor never stops the build. As an independent distributor, our value is availability across that short list — including the Artery AT32 we stock — with honest documentation, not authorised-distributor warranties. This guide is the procurement view.
1. Build a resilient MCU short list
We stock the Artery AT32F4 plus the main F103-class alternatives and the original STM32, all in one place.
| Part | Notes | Link |
|---|---|---|
| AT32F403ACGT7 | Artery AT32F4, STM32F103C8T6 alternative | AT32F403ACGT7 |
| STM32F103C8T6 | Original F103 reference device | STM32F103C8T6 |
| GD32F103C8T6 | GigaDevice F103-class alternative | GD32F103C8T6 |
| CH32F103C8T6 | WCH F103-class alternative | CH32F103C8T6 |
| APM32F103C8T6 | Geehy F103-class alternative | APM32F103C8T6 |
| CKS32F103C8T6 | CETC F103-class alternative | CKS32F103C8T6 |
| HK32F103C8T6 | HKMicro F103-class alternative | HK32F103C8T6 |
2. What we can and cannot promise
- Availability — we quote what is actually in stock or sourceable, with date codes.
- Not authorised — we are an independent distributor; no manufacturer warranty or franchise. Verify specs against the official datasheet before design-in.
- Authenticity process — traceable sources, date-code and lot checks, and inspection/X-ray/electrical test on request for critical parts.
3. How to buy from the open market safely
- Send the full part number with suffix, package, quantity and target price.
- Start with a sample before committing to volume on a new source.
- Keep lot records so any field failure traces back to its origin.
- For a whole BOM, let us quote the lines we can supply and flag the rest.

Frequently asked questions
Do you franchise Artery microcontrollers?
No. We are an independent distributor of electronic components, not an authorised distributor or representative of Artery or any manufacturer named here. We stock selected AT32 and other Cortex-M devices based on availability, and we describe them honestly as alternatives where that is how they are offered.
Why qualify multiple MCU sources?
Because allocation and lead-time risk is real. A build that depends on a single microcontroller source stops when that source is allocated. Qualifying Arter, GD32, CH32, APM32, CKS32, HK32 and the original STM32 lets you shift volume to whatever is available, with the same footprint.
What should I send for an MCU quote?
The exact part number including suffix, the package, the quantity, your target price, any date-code requirement, and whether you need samples first. The more complete the request, the faster and more accurate the quote.
Can you quote a whole MCU BOM?
Yes. Send the complete bill of materials and we will quote the lines we can supply, flag constrained or obsolete lines, and propose in-stock alternatives where a part is unavailable.
