STMicroelectronics second generation STM32 microprocessors

STMicroelectronics has launched the second generation of its STM32 MPUs (microprocessors), coming with a new architecture built upon the same ecosystem and raising performance and security for applications at the industrial and IoT edge.

The STM32MP2 Series devices combine 64-bit cores with Edge AI acceleration, advanced multimedia features, graphics processing and digital connectivity. The microprocessors also integrate advanced security features in hardware.

The STM32MP25 is available with single or dual 64-bit Arm Cortex-A35 cores running at 1.5 GHz, complemented with a 400 MHz Cortex-M33 embedded core that handles real-time processing. A dedicated neural processing unit (NPU) adds up to 1.35 TOPS (tera-operations per second) of computing muscle for Edge AI acceleration in applications such as advanced machine vision and predictive maintenance. With support for 32-bit DDR4 and LPDDR4 memories, the STM32MP25 is designed to provide long-term support for cost-optimised designs.

Also featuring Gigabit time-sensitive networking (TSN) support and a two-port Gigabit Ethernet TSN switch, with PCIe, USB 3.0 and CAN-FD peripherals, the microprocessor product line provides intensive connectivity for real-time industrial applications, data concentrators and gateways, and communication equipment. Combined, the processing and networking capabilities enhance detection and feature recognition for security applications and industrial automation.

A 3D graphics processing unit (GPU) with 1080p resolution permits rich user interfaces, with support including Vulkan real-time graphics for Android applications. A 1080p encoder/decoder and multiple display connections including LVDS, 4-lane MIPI DSI, and a MIPI CSI-2 camera interface simplify connecting displays and digital cameras including raw-Bayer image sensors.

The microprocessors also feature SESIP Level 3 certification include Arm’s TrustZone architecture and resource isolation framework (RIF). This is complemented with secure key storage, secure boot, a unique device ID in one-time programmable (OTP) memory, hardware cryptographic engines, and on-the-fly DDR encryption/decryption.
