These are ST’s first MPUs to contain a 64-bit central processing unit (CPU), the Arm Cortex^®-A35, which runs up to 1.5GHz to raise the main processing capability compared to the first-generation STM32MP1 devices.

The CPU is the center of a true heterogeneous processing engine that also contains a Cortex-M33 core. In addition, there is a graphics processor (GPU), neural processor (NPU), and a video processor (VPU). AI workloads can run on the CPU, GPU, or NPU depending on processor loading and application demands, for optimal performance and energy efficiency. In fact, the high efficiency of these MPUs permits system designs to go without active cooling, gaining advantages such as smaller size, silent operation, greater reliability, and reduced power consumption.
The 3D GPU supports up to 1080p displays and the powerful multimedia features also include a full-HD video pipeline with parallel LVDS and DSI interfaces. Together with a MIPI CSI-2 camera interface with ISP, these enhance support for cutting-edge machine-vision applications.
There are further powerful industrial interfaces, including up to three Gigabit Ethernet ports with a 2-port switch and support for Ethernet time-sensitive networking (TSN). There are also PCIe Gen2, USB 3.0, and three CAN-FD interfaces that ease integration in a wide variety of communication and control applications.

The devices are fully supported with STM32 development resources that are familiar to engineers working with ST’s STM32 microcontrollers (MCUs) and STM32 microprocessors. The STM32Cube ecosystem provides tools and dedicated MPU software packs including OpenSTLinux and OpenSTDroid for Android support. There are also evaluation boards that provide further help to simplify development and accelerate project completion. "
