AT32F406CEU7

AT32F406CEU7 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, three 12-bit ADCs up to 5.33 Msps, eight SPI, three I2C and eight UART-class channels, one QSPI and 41 GPIO on a 2.4 V to 3.6 V supply over -40 to +105 C. Selection advice: Artery's official selector table lists this code in the CE column (the 512 KB tier; the CC code is the 256 KB / 128 KB tier in the same footprint), and the F406 has no USB - designs needing high-speed USB should take the AT32F408CEU7 with its on-chip HS PHY in the same package; Artery's September 2026 launch release states the F406/F408 series is available for samples and mass production. Parameters verified against the Artery AT32F406 selector table.
