AT32F423 — value-optimized MCU family in the Artery AT32 portfolio
The AT32F423 is a value-optimized MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to 150 MHz system clock, with up to None KB of on-chip Flash and 48, 32 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 QFN324x4 mm, QFN366x6 mm, QFN486x6 mm, LQFP487x7 mm, LQFP647x7 mm, LQFP6410x10 mm, LQFP10014x14 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
