AT32F407RET7

AT32F407RET7 is a 32-bit Arm Cortex-M4F microcontroller from Artery Technology in an LQFP-64 package, running at 240 MHz with 512 KB of Flash and an integrated Ethernet MAC, for connected industrial controls, gateways and equipment that needs wired networking on the main MCU. The on-chip Ethernet MAC is the selection point within Artery's 240 MHz line: it removes an external MAC device and keeps the network stack on the same device that runs the application, which simplifies the board and the firmware partition. Selection advice: the E in RET7 is the 512 KB Flash grade - match the density letter character-for-character against your BOM, because the F407 ships in several Flash tiers in the same LQFP-64 footprint and firmware images are built per density. If your board has no Ethernet, the AT32F403ARET7 is the same-tier alternative without the MAC; if wired connectivity is a requirement, stay with the F407 code.
