AT32F437 — high-performance MCU family in the Artery AT32 portfolio
The AT32F437 is a high-performance MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to 288 MHz system clock, with up to 4032 KB of on-chip Flash and 384KB(Default), Configurable up to 512KB KB of SRAM, built around a high-efficiency ARM Cortex-M core.
The family is aimed at HMI panels, industrial gateways and graphics-oriented designs that need wide I/O and external memory alongside high compute. Offered in LQFP6410x10 mm, BGA1007x7 mm, LQFP10014x14 mm, LQFP14420x20 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
