STMicro VL53L9 is a high-resolution, direct Time-of-Flight 3D LiDAR sensor module

STMicro VL53L9 ToF LiDAR sensor

The STMicro VL53L9 sensor is the latest addition to the company’s FlightSense product family. The direct Time-of-Flight (ToF) 3D LIDAR (light detection and ranging) sensor offers a resolution of up to 2,300 zones. The module is described as all-in-one and easy to integrate. It comes in a small, reflowable package that contains all the necessary components for sensing objects and processing images. The sensor features an array of single photon avalanche diodes (SPADs) for photon detection, a post-processing SoC, and two vertical surface emitting lasers (VCSELs) powered by a dedicated bipolar-CMOS-DMOS (BCD) VCSEL. The VL53L9 is a multi-zone ToF sensor similar to the VL53L7CX and the VL53L8, meaning that it offers multi-zone distance measurements up to 54 x 42 zones with a wide 54° x 42° field-of-view. Unlike most IR sensors, the VL53L9 sensor uses backside illumination direct ToF technology to ensure absolute distance measurement, regardless of the target color […]

STMicro ST60A3H0 and ST60A3H1 60 GHz transceiver ICs aim to replace USB cables

ST60A3H0 ST60A3H1 60 GHz transceivers

STMicro ST60A3H0 and ST60A3H1 are short-range 60 GHz transceiver ICs that tunnel eUSB2, I2C, SPI, UART, and GPIO signals and aim to replace USB and other cables in consumer devices such as digital cameras, wearables, portable hard drives, and small gaming terminals. They should also find their way into industrial applications such as rotating machinery where cable use may be challenging. The smaller ST60A3H0 chip provides more flexibility and requires an external antenna, while the ST60A3H1 chip is a fully integrated solution with a built-in linear antenna. Both are capable of USB 2.0 speeds of up to 480 Mbps and support UART, GPIO, and/or I2C signals so they are not limited to USB cables and can be used in a range of applications. ST60A3H0 and ST60A3H1 key features and specifications: 60 GHz V-Band transceiver for short-range contactless connectivity up to 480 Mbit/s eUSB2, UART, GPIO, or I2C RF tunneling Low […]

STMicro STM32WL5MOC SiP Module is pre-certified for LoRaWAN & Sigfox networks

STM32WL5MOC wireless prototyping board

STMicroelectronics has recently introduced the STM32WL5MOC system in package (SiP) module with a dual-core STM32 microcontroller, sub-1 GHz RF radio, power supply, and passive components into a 10×10 mm LGA package. According to ST, the new chip uses the STM32WL module which we have seen used in Arduino MKR-inspired MKR Windy board, smart building, and many other LoRa devices. STMicroelectronics’ STM32WL, an Arm Cortex-M0+ microcontroller, operates in sub-GHz ISM bands (413-479MHz, 826-958MHz, and 169MHz later in 2024) for protocols like wireless M-Bus (mode N) and Wize. It supports multi-protocol and multi-modulation (4-(G)FSK, 2-(G)FSK, (G)MSK, DBPSK, DSSS, OOK, ASK) for various wireless standards (Sigfox, KNX, WiSun, mioty, M-Bus, etc.) and introduces power-saving features for up to 15 years of battery life. STM32WL5MOC SiP module specifications: Core Specifications:  STM32WL55JC SoC with 32-bit Arm Cortex-M4 and Cortex-M0+ CPUs, up to 48 MHz. Adaptive real-time accelerator (ART Accelerator) for efficient flash memory execution. DSP instructions […]

STMicro VD55G1 – A small, low-power global shutter I3C camera sensor for computer vision

STMicro VD55G1 global shutter camera sensor

STMicro VD55G1 is a new global shutter I3C camera sensor with a small die size of 2.7 x 2.2 mm, 804 x 704 pixels native resolution, and consuming about 1mW in its ‘always-on’ autonomous mode to wake up the host when motion is detected. Camera sensors are available with rolling or global shutter, with most from the former type, but as we’ve seen in our reviews of the e-Con Systems See3CAM_24CUG (USB 3.1) and the Raspberry Pi Global Shutter (MIPI CSI) global shutter cameras, the latter is much better we capturing moving objects clearly at high frame rates with fewer artifacts than with rolling cameras. The VD55G1 global shutter sensor will also benefit from the same advantage but is offered in a smaller package working over MIPI CSI and/or I3C, making it suitable for devices with small batteries used in applications such as eye tracking or motion estimation. STMicro VD55G1 […]

STMicro STM32WL3 sub-GHz wireless MCU targets smart metering, smart building, and industrial monitoring


STMicroelectronics STM32WL3 is an Arm Cortex-M0+ low-power, long-range, multi-protocol wireless microcontroller working in sub-GHz ISM frequency bands, namely 413MHz – 479MHz, 826MHz – 958MHz, and soon 169MHz (2024) for protocols such as wireless M-Bus (mode N) and Wize. The multi-protocol and multi-modulation radio supports 4-(G)FSK up to 600kbit/s, 2-(G)FSK, (G)MSK, DBPSK, DSSS, OOK, ASK modulation schemes suitable for proprietary and standardized wireless protocols such as Sigfox, KNX, WiSun, mioty, M-Bus, and others.

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

STMicro STHS34PF80 IR sensor

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 […]

VL53L7CX Time-of-Flight (ToF) sensor offers camera-like 90° field of view

VL53L7CX wide FoV ToF sensor

STMicroelectronics VL53L7CX is the latest FlightSense multi-zone Time-of-Flight (ToF) distance sensor from the company with the main highlight between its camera-like 90° diagonal field of view, derived from a 60° x 60° field of view… This is a significant improvement over the 61° diagonal field of view of the previous generation ToF sensors such as the VL53L8 or VL53L5CP,  and the wider field-of-view is said to bring “lifelike situational awareness” to applications like home automation, computers, house appliances, robots, and industrial equipment with full-privacy since ToF sensors do not capture photos or videos like traditional cameras. STMicro VL53L7CX key features and specifications: 940 nm invisible light vertical cavity surface emitting laser (VCSEL) and integrated analog driver 60° x 60° square field of view (FoV) (90° diagonal) using diffractive optical elements (DOE) on both transmitter and receiver enabling square FoV Receiving array of single photon avalanche diodes (SPADs) Multizone ranging output […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets


Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]
