STM32U3B5/C5 ultra-low-power MCU features 640 KB RAM, 2 MB Flash, and HSP accelerator to run AI without batteries

STMicroelectronics has added two members to the STM32U3 ultra-low-power Arm Cortex-M33 microcontroller family: the STM32U3B5 and STM32U3C5 MCUs get more resources with up to 640 KB SRAM and 2 MB flash, as well as an HSP (hardware signal processor) accelerator to run AI/ML workloads without batteries, just using energy harvesting. The new chips are still clocked at up to 96 MHz, benefit from a near-threshold design (down to 0.65 V), allowing a power consumption of just 117 Coremark/mW in active mode, and can operate up to 105°C ambient temperature. They come with one additional group of interfaces, bringing the total to four SPI and I2C, two I3C and CAN-FD, and five UARTs, as well as five more 16-bit timers, for a total of 10. The STM32U3C5 also includes a cryptocore to accelerate encryption and decryption operations, and supports the CCB (Coupling and Chaining Bridge) hardware security feature, both of which […]

STMicroelectronics Stellar P3E quad-core Arm Cortex-R52+ automotive MCU features Neural-ART AI accelerator

Stellar P3E AI automotive MCU Block Diagram

STMicroelectronics has introduced the Stellar P3E, the first automotive MCU with an embedded Neural-ART AI accelerator, designed to simplify X-in-1 Electronic Control Units (ECUs) by consolidating powertrain functions like the inverter, on-board charger (OBC), and DC-DC converter into a single module. The MCU enables smart sensing, predictive maintenance, and virtual sensor applications without the cost and complexity of a separate SoC. The microcontroller features four 500 MHz Arm Cortex-R52+ cores with 19.5 MB of xMemory, which is based on phase-change memory (PCM), offering roughly twice the density of embedded flash. The chip integrates multiple ADC channels for precise sensing, high-resolution PWM down to 102 ps for fine motor control, and 10 timer modules for deterministic real-time operation. Connectivity options include Gigabit Ethernet and CAN-XL, for high-speed, low-latency in-vehicle communication. Stellar P3E (SR6P3EC4/SR6P3EC6) specifications: MCU – SR6P3EC4 / SR6P3EC6 CPU Cores – 4x Arm Cortex‑R52+ cores at up to 500 MHz; […]

5 Ways Embedded AI Processors are Revolutionizing Device Performance (Sponsored)

Artificial intelligence (AI) is moving from cloud-first architectures to edge-first designs, so more processing now runs on phones, cameras, and embedded controllers. Running inference on-device cuts latency and keeps sensitive data local. This momentum is reshaping product roadmaps, all due to different revolutions driven by edge AI. The Core Revolutions Driven by Edge AI Instead of routing every model and signal to the cloud, devices are processing more data locally to act faster and protect sensitive information. Because edge AI is changing where intelligence runs, IDC estimates global spending on edge computing reached about $261 billion in 2025. This rapid enterprise investment is due to several reasons. 1. Enabling Real-Time, On-Device Decisions Eliminating the cloud round-trip lets devices turn sensor input into action in milliseconds. This capability is essential for industrial automation and control loops because embedded AI processors run optimized models on-device, so decisions happen continuously. 2. Strengthening Privacy […]

ST’s Human Presence Detection (HPD) solution tracks head and posture with AI and VL53L8CP ToF sensor

VL53L8CP ToF sensor for AI presence detection

Back in 2022, we first saw STMicro launch the VL53L5CP ToF presence detection sensor for the PC market with features like user detection, gesture recognition, and intruder alert. Building upon that, the company has recently released its 5th‑generation Human Presence Detection (HPD) solution, built around the VL53L8CP 8×8 multizone Time‑of‑Flight sensor family with edge AI features offered as a turnkey solution for laptops, PCs, monitors, and accessories. We have seen and even tested earlier ToF sensors like the VL53L0X and VL53L1X, which used a single-photon avalanche diode (SPAD) for single-zone ranging. After that, we saw ST release the VL53L5, which was a major upgrade with up to 64-zone multi-zone support, enabling features like touch-to-focus and object tracking. Now, in the age of AI, ST has launched a 5th-gen turnkey HPD solution built around the VL53L8CP sensor. STMicro HPD solution specifications: Sensor – ST FlightSense VL53L8CP 5th generation multi-zone direct Time-of-Flight (dToF) […]
