Artery Technology

Artery Technology is a Taiwan-based MCU vendor whose AT32 family targets cost-sensitive motor control, appliance and consumer designs; the profiles here cover its AT32F406 and AT32F408 lines. Both run an Arm Cortex-M4F core at 216 MHz with FPU and DSP instructions, three 12-bit ADCs up to 5.33 Msps, eight SPI ports and a QSPI interface on a 2.4 V to 3.6 V supply over -40 to +105 C. Ordering codes encode memory tier and package: CC/RC codes carry 256 KB Flash and 128 KB SRAM, CE/RE codes step up to 512 KB and 192 KB, U7 marks QFN-48 and T7-7 the LQFP-64, with -7R forms as tape-and-reel supply. The family's one functional split is USB - the AT32F408 integrates high-speed USB OTG with an on-chip PHY, while the AT32F406 omits USB and returns the pins to GPIO.

Sourcing notes for Artery Technology parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
