EETE JAN 2016 Analog design Time-of-flight ranging sensor for cameras, robotics, IoT Promising to ‘revolutionise mobile-camera Performance and enable new applications in robotics and IoT, ST Microelectronics’ FlightSense VL53L0 low-power, miniature sensors can be used for fast autofocus in smartphones, for proximity sensing, and object detection This is ST’s second-generation laser-ranging sensor based on its FlightSense technology. VL53L0, can range faster, over longer distances, and more accurately. In a form factor of 4.4x2.4x1mm, ST says the VL53L0 is the smallest ToF (Time-of-Flight) module available, and the first to integrate a 940 nm VCSEL (vertical cavity surface-emitting laser) light source, a SPAD (single-photon avalanche diode) photon detector, and an advanced microcontroller to manage the complete ranging function. Being the market’s first module to use light emitted at 940 nm, coupled to leading-edge infrared filters, the VL53L0 maximises ambient light immunity and is now invisible to the human eye. The embedded microcontroller and digital algorithms minimise both the host processing and system power consumption in the final application. The VL53L0 is able to perform a full measurement operation in one image frame, typically less than 30ms, at distances beyond 2m. STMicroelectronics 360° programmable magnetic angle position sensor A1335 from Allegro MicroSystems Europe is a 360° contactless high-resolution programmable magnetic angle position sensor IC designed for use in digital systems in automotive and related applications involving rotating shaft sensing. It is available as single or dual independent die in a single package. The device has a systemon chip (SoC) architecture with a front end based on circular vertical Hall technology and programmable microprocessorbased signal processing. It supports multiple communication interfaces including I²C, SPI (Serial Peripheral Interface), and SENT (Single Edge Nibble Transmission). In addition to providing 360° angular measurement, the A1335 provides two options for on-chip linearisation: harmonic linearisation to handle applications that require side-shaft magnetic configurations; and segmented linearisation for scaling angle measurement applications requiring less than 360° of motion (so-called “short stroke” applications). It also includes on-chip EEPROM technology, capable of supporting up to 100 read/ write cycles, for flexible programming of calibration parameters.
