The AT32F435CMT7 is a member of Artery Technology's (雅特力) AT32 F435 high-performance MCU family: a Cortex-M4F core running at up to 288 MHz, in an LQFP48 package, with up to 4032 KB of Flash on the device. It is the kind of part that lands on a BOM when a design needs meaningfully more compute than a mainstream M0+/M3 part can give, but the project does not want to move to an application processor.
Where this class of MCU earns its place
A 288 MHz Cortex-M4F with floating-point support suits workloads that mix control and signal processing: motor drives with field-oriented control, industrial gateways that run a communication stack alongside real-time I/O, inverter and power-conversion control, and HMI panels that need responsive graphics with a modest frame buffer. The large Flash allocation also helps teams that ship multiple SKUs from one hardware platform and would rather not optimise code size aggressively.
What to confirm before you order
- Package variant. The ordering code encodes the package and pin count. LQFP48 is what our current lot carries — verify it matches your footprint and your thermal/clearance requirements.
- Flash and temperature grade you actually need. Buying a larger Flash option than required is a straightforward way to overspend; buying too small forces a late redesign.
- Date code and lot. We publish the date code of the lot on offer so your incoming inspection has something to check against.
- Tooling and firmware path. If this is a migration rather than a new design, budget time for the port. Peripheral naming and register behaviour are not identical across vendors.
Choosing within the same family
| Need | Practical direction | Why |
|---|---|---|
| More I/O than LQFP48 offers | Look at higher pin-count AT32F435 variants | AT32F435VMT7 |
| Cost-sensitive, same core family | Smaller Flash AT32F435 variant | AT32F435CGT7 |
| Mainstream rather than flagship performance | AT32F405 / AT32F425 families | AT32F405CCT7 |
| Different performance tier entirely | Compare within the MCU range | microcontroller catalogue |
Sourcing reality for high-performance MCUs
Popular performance parts are exactly the ones that disappear from franchise distribution first when demand spikes. If this device is on a production BOM, it is worth holding a buffer lot rather than buying hand-to-mouth, and worth asking a spot supplier to watch the line for you. We hold the AT32F435CMT7 in spot inventory with MOQ from a single piece, and the wider MCU range covers the rest of the family.
