ST VL53L9CX direct Time-of-Flight 3D LiDAR supports 5cm to 9m range, 2.3K zones resolution

STMicroelectronics VL53L9CX, or VL53L9 for short, is the company's first direct Time-of-Flight (dToF) 3D LiDAR all-in-one module. It offers a sensing range of  5 centimeters to 9 meters, a wide 72º field of view, a resolution of 2.3K zones, and up to 100 Hz frame rate. ST's ToF sensors have gone a long way since we covered the VL53L0X sensor with a single zone and 2-meter range in 2017. Since then, the company has steadily improved its tiny ToF sensors with up to 64 zones and long range in recent sensors like the VL53L8CP. While the VL53L9CX is still tiny at 12.8 x 6.1 x 4.6 mm, it's in a class of its own, acting like a mini 3D scanner with 2268 zones, and will be used for a range of applications in robotics, industrial automation, smart buildings, AR/VR, and healthcare.

STMicro VD65G4 and VD55G4 0.56MP global shutter image sensors enable ultra-low-power always-on event-driven vision

STMicroelectronics VD65G4 and VD55G4 are ultra-low-power 0.56-megapixel global shutter CMOS image sensors designed for battery-operated edge AI and always-on vision applications. The main difference between the two sensors is that the VD65G4 features a color RGB Bayer pattern, while the VD55G4 is a monochrome sensor designed to capture visible to near-infrared (NIR) light. Both sensors use a compact 1/9-inch optical format and a 2.16 µm pixel pitch, utilizing Back Side Illuminated (BSI), CDTI, and 3D stacking technologies to achieve a tiny 2.73 x 2.16 mm bare-die footprint. STMicro VD65G4 and VD55G4 specifications: Resolution – 0.56 MP (804 x 704) Chroma VD65G4 – RGB Bayer (RGGB). VD55G4  – Monochrome (Clear, Visible to NIR). Optical Characteristics – 1/9-inch (2.3mm) optical format with a 30° linear CRA and close to 1:1 aspect ratio. Pixel Technology – 2.16 µm x 2.16 µm pixel size utilizing global shutter, BSI, CDTI, and 3D stacking. Frame Rates

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

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.
