AT32F455 — mainstream MCU family in the Artery AT32 portfolio
The AT32F455 is a mainstream MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to 192 MHz system clock, with up to None KB of on-chip Flash and 96+12, 128+16 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 QFN486x6 mm, LQFP487x7 mm, LQFP6410x10 mm, LQFP10014x14 mm, LQFP14420x20 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
