AT32F490 — mainstream MCU family in the Artery AT32 portfolio
The AT32F490 is a mainstream MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to None MHz system clock, with up to 256 KB of on-chip Flash and 96+6, PSRAM (MB), 2 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 LQFP6410x10 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
