AT32F425 — value-optimized MCU family in the Artery AT32 portfolio
The AT32F425 is a value-optimized MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to None MHz system clock, with up to 64 KB of on-chip Flash and 20 KB of SRAM, built around a high-efficiency ARM Cortex-M core.
The family is aimed at high-volume consumer and cost-sensitive products that still want 32-bit processing and a real peripheral set. Offered in TSSOP206.5x4.4 mm, QFN324x4 mm, LQFP327x7 mm, QFN486x6 mm, LQFP487x7 mm, LQFP647x7 mm, LQFP6410x10 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
