STMicro LSM6DSV32X Edge AI motion sensor aims to extend battery life in wearables, trackers, and activity monitors

STMicro LSM6DSV32X is a new low-power 6-axis inertial module with the company’s machine-learning core (MLC) with AI algorithms based on decision trees, a 3-axis accelerometer with a full-scale range of 32g, and a 4000 degrees-per-second gyroscope designed to measure intensive movements, impacts, and freefall height (estimation). The features of the sensors enable it to lower the power consumption for functions such as gym-activity recognition to under 6µA, while 3D orientation tracking consumes just 30µA when using STMicro’s Sensor Fusion Low-Power (SFLP) algorithm. It will be found in a range of battery-powered devices such as consumer wearables, asset trackers, and impact and fall alarms for workers or the elderly. STMicro LSM6DSV32X specifications: Triple-channel architecture for UI (user interface), EIS, and OIS data processing Data storage – Smart FIFO up to 4.5 KB Sensors Accelerometer – ±4/±8/±16/±32 g full scale Gyroscope – ±125/±250/±500/±1000/±2000/±4000 dps full scale Embedded temperature sensor Host interfaces SPI, […]

600 MHz STM32H7R/S Cortex-M7 MCUs feature 620KB SRAM, 64KB boot flash, optional NeoChrom GPU

STMicro has launched the high-performance 600 MHz STM32H7R/S Arm Cortex-M7 microcontrollers: the STM32H7R3/S3 General-purpose MCU lines, and STM32H7R7/S7 graphics MCU lines adding a NeoChrom 2.5D GPU. Both ship with a large 620KB SRAM and a small 64KB boot flash. The reason for the small boot flash is to have the application code and data stored off-chip memory ICs to provide more flexibility to customers when it comes to the choice of memory type and capacity to fulfill the application requirements and lower the BoM cost. The “S” in the STM32H7S microcontrollers stands for Security with a crypto/hash engine that can help the final product achieve SESIP Level 3 and/or PSA Certified Level 3 certifications. Many of the specifications are similar to the STM32H7 microcontrollers, but performance is better going slightly faster than the 550MHz STM32H7 MCUs added in 2020, and the STM32H7R/S adds some new features: 200 MHz Hexadeca SPI […]

STMicro STHS34PF80 IR sensor for motion and presence detection aims to replace PIR sensors

STMicro STHS34PF80 is a new IR sensor designed for IoT and Smart Home devices requiring motion and/or presence detection that offers an alternative to traditional passive infrared (PIR) sensors and is mostly useful for building automation. The latest IR sensor from STMicro contains thermal transistors (MOSFETs) that can not only detect motion but also stationary objects, something that’s not feasible with conventional PIR detectors that require motion for object detection. The company further adds that PIR sensors need a Fresnel lens to sense moving objects, but the STHS34PF80 detector does not require a lens and as a result, enables much smaller designs. STHS34PF80 key features and specifications: Range up to 4 meters without lens for objects measuring 70 x 25 cm² Integrated silicon IR filter IR sensitivity – 2000 LSB/°C RMS noise – 25 LSBrms Operating wavelength – 5 µm to 20 µm Local temperature sensor accuracy – ±0.3 °C […]
