AT32F406CCU7

AT32F406CCU7 is an Artery Technology AT32F406 microcontroller in a QFN-48 package (6 x 6 mm), built on an Arm Cortex-M4F core at 216 MHz with 256 KB of Flash and 128 KB of SRAM. It carries 41 GPIO, three 12-bit ADCs (10 channels in this package), eight SPI ports, three I2C ports and a QSPI interface over -40 to +105 C. Selection advice: the F406 is the family member without USB - the pins go back to GPIO - so designs that need USB OTG should step to the AT32F408 in the same package; the CC code is the 256 KB tier, while CE codes step up to 512 KB. Artery lists the F406/F408 series as available for sampling and mass production, and the selector table on its product page prints this exact code. Parameters verified against Artery Technology documentation.
