AT32F403A Series

AT32F403A high-performance microcontrollers, powered by 32-bit ARM® Cortex®-M4 core, utilize advanced process to achieve 240 MHz computing speed. The embedded single precision floating-point unit (FPU) and digital signal processor (DSP), rich peripherals and flexible clock control mechanism can meet an extensive range of applications. The superior memory design supports up to 1 MB Flash memory and 224 KB SRAM, with the excellent Flash access zero wait far beyond the same level of the chip industry.

In addition to highly efficient computing performance, AT32F403A series also imports the Security Library to support the use of password to protect the specified program area, in which IDH programs the core algorithm and provides to downstream customers for secondary development. Meanwhile, AT32F403A series supports eight sets of UART serial interfaces and two sets of CAN buses that are well suited for IoT applications. The USB device applications without the need of external crystal oscillators can not only enhance the reliability of terminal products but reduce costs as well.
