AT32F408CCU7

AT32F408CCU7 is an Artery Technology AT32F408 microcontroller in a QFN-48 package (6 x 6 mm), running an Arm Cortex-M4F core at 216 MHz with 256 KB of Flash and 128 KB of SRAM. Its defining feature is the high-speed USB OTG peripheral with on-chip PHY and a dedicated 4 KB FIFO, which the AT32F406 in the same package omits; the pin budget reflects that choice, with 38 GPIO and three 12-bit ADCs (10 channels) over -40 to +105 C. Selection advice: choose the F408 CC code when the product needs a USB device or host port without an external PHY; if USB is not needed, the F406 CC code returns pins to GPIO in the same footprint. Artery lists the series in mass production and its selector table prints this exact code. Parameters verified against Artery Technology documentation.
