AT32F408CEU7

AT32F408CEU7 is a 32-bit Arm Cortex-M4F microcontroller from Artery Technology in a QFN-48 package (6 x 6 mm), running at 216 MHz with 512 KB of Flash and 192 KB of SRAM and a USB OTG high-speed interface with on-chip PHY and a dedicated 4 KB FIFO - no external HS PHY is needed - alongside three 12-bit ADCs up to 5.33 Msps, eight SPI and eight UART-class channels on a 2.4 V to 3.6 V supply over -40 to +105 C. Selection advice: the USB pins consume GPIO, so this package offers 38 GPIO against the AT32F406CEU7's 41 in the same footprint and memory tier; pick the F406 code when USB is unused and I/O count matters more. Artery's launch release confirms mass production of the series. Parameters verified against the Artery AT32F408 selector table.
