ARTERY AT32F421C6T7
The AT32F421 is based on the high-performance ARM®Cortex®-M4 32-bit RISC core running up to 120 MHz. The Cortex®-M4 core features a full set of DSP instructions and a memory protection unit (MPU). The AT32F421 incorporates high-speed embedded memories (up to 64 Kbytes of internal Flash memory and 16 Kbytes of SRAM), enhanced GPIOs and peripherals connected to two APB buses.FEATURES
