AT32F413 series microcontrollers, powered by 32-bit ARM® Cortex®-M4 core, utilize advanced process to achieve 200 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 a wide range of applications. It features up to 256 KB Flash memory, 64 KB SRAM and Flash access zero wait far beyond the same level of chip industry.
AT32F413 series is among the first products to introduce the Security Library, which supports the use of passwords to protect the specified program area so that IDH can program the core algorithm into this area and provides to downstream customers for secondary development.
AT32F413 devices can not only perform well in the temperature range of -40 to 105¡ãC , and but also provide a variety of chips for selection in response to diverse memory requirements. Through its powerful on-chip resource allocation, high integration and cost-effective performance, they are able to maintain its competitive edge to become the best choice for industrial automation, motor control, IoT, consumer electronics and other cost-sensitive and high-computing requirements.
