AT32F407 — mainstream MCU family in the Artery AT32 portfolio
The AT32F407 is a mainstream MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to 240 MHz system clock, with up to 1024 KB of on-chip Flash and 96+128 KB of SRAM, built around a high-efficiency ARM Cortex-M core.
The family is aimed at general-purpose control, instrumentation and consumer designs needing a balanced mix of Flash, SRAM, I/O and interfaces. Offered in LQFP64 10x10 mm, LQFP100 14x14 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
