STMicroelectronics has introduced its latest 64-bit microcontroller, the STM32MP2. With multiple Arm Cortex cores, a neural processing unit, a graphics gas pedal and multiple high-performance I/O options, ST is targeting the new processor for machine learning in Industry 4.0 applications.
The STM32MP2 microprocessor unit (MPU) features a single or dual Arm Cortex-A35 cores (1.5 GHz) for high-performance tasks and an Arm Cortex-M33 (400 MHz) for efficiency tasks. There is also a DDR4/LPDDR4 interface, neural processing unit, 3D CPU and connectivity. With the A35 core, the STM32MP2 supports OpenSTLinux, the mainline Linux distribution based on Yocto. Previously, it supported STM32MP1 MPUs with single- or dual-core Arm Cortex-A7. The M33 core can run either bare-metal code or a real-time operating system (RTOS). Existing STM32 developers familiar with the STM32MP1 can use the same STM32Cube development tools for the new STM32MP2. In addition, third-party support is available for porting code from Android applications. With its MIPI CSI-2 interface for cameras, 1.35 TOPS per second NPU and time-sensitive network support, the STM32MP2 is well suited for vision-based machine learning activities. For example, ST says the STM32MP2 can transmit video from a five-megapixel sensor at 30 frames per second in real time while analyzing it using an AI gas pedal and sending h.264-encoded video over Gigabit Ethernet. On the visual side, the 3D GPU supports 1080p video via a hardware decoder. Display interfaces include RGB, MIPI DSI and LVDS. Time-sensitive Gigabit Ethernet is one of the many connectivity options available. The STM32MP2 also supports high-performance interfaces such as PCI-Express Gen2, USB 3.0 and three CAN-FDs. Security features include Security Evaluation Standard for Internet of Things Platform (SESIP) Level 3 certification, Arm TrustZone on the Cortex-A and Cortex-M cores, and ST's robust hardware encryption. The processor is part of ST's long-term support with a 10-year life plan. ST plans to provide samples by the end of 2023 and begin shipping in the first half of 2024.
