u-blox introduces new LTE-M modules with integrated GNSS to boost industrial connectivity  

Wed, Feb 07, 2024

u-blox has announced two new LTE-M cellular module series, the SARA-R52 and LEXI-R52. These modules, designed for industrial applications, are based on the u-blox UBX-R52 cellular chip and are tailored for integrated and concurrent positioning and wireless communication needs. Typical IoT use cases include fixed and mobile applications such as metering and utility, asset tracking and monitoring, as well as healthcare.

A set of new features embedded within the u-blox UBX-R52 chip will allow users to dispense with additional components to design their products. SpotNow is a new positioning feature unique to u-blox, which provides position data with a 10 m accuracy within a couple of seconds. It is meant for occasional tracking applications such as recycling waste dumpsters, elderly trackers, or cleaning machines. The uCPU feature allows users to run their own software within the chip without using an external MCU. The uSCM (Smart Connection Manager), on the other hand, is designed for automatic connectivity management to achieve either best performance or lowest power consumption, for example when a connection is lost and needs to be re-established.

The new u-blox R52 series also introduces a new combo module designed to offer simultaneous GNSS and cellular connectivity – an important attribute for applications requiring continuous or cyclic tracking. The u-blox SARA-R520M10 combo module comes equipped with an integrated u-blox M10 GNSS receiver and ensures concurrent tracking with low-power consumption, better TTFF, and improved RF sensitivity. It is tailored for users who seek the simplicity of a pre-integrated cellular and GNSS solution.

Many LTE-M modules only offer an RF output power of 20-21 dBm, whereas the new R52 series offers 23 dBm, ensuring stable connectivity in challenging coverage conditions. The LEXI-R52 provides the same features as the SARA-R52, but in a smaller form factor (16 x 16 x 2 mm), ideal for ultra-small applications like wearables.

Samples are available now, with volume production scheduled for Q3 2024.

Infineon presents hybrid Time of Flight technology for next-generation smart robots

Wed, Jan 31, 2024

In collaboration with device manufacturer OMS and pmdtechnologies, an expert in Time of Flight (ToF) technology, Infineon has developed a new high-resolution camera solution that enables enhanced depth sensing and 3D scene understanding for next-generation smart consumer robots. The new hybrid Time of Flight (hToF) solution combines two depth sensing concepts and helps significantly reduce maintenance effort and costs for smart robots.

Infineon’s REAL3 flexible ToF imager technology enables the combination of established high-resolution iToF flood illumination and dToF long-range spot illumination in a single hybrid Time of Flight camera. For many years now, this high-resolution technology has been used to see the smallest objects in the path of the robot and navigate around them. Adding precise long-range spot data now also allows creation of an accurate 3D map of the surrounding area for intelligent path planning experiences even in challenging light conditions of bright sunlight or darkness that empower the next-generation robot vacuum cleaner.

The new solution reduces the height of robot vacuum cleaners by 20-30 percent, fully replacing the top-mounted LDS (Laser Distance Scanner) making it possible to clean even under furniture with low clearance. Measuring only 31x16x8 mm, the hybrid ToF camera requires much less space for improved mapping and obstacle avoidance functionality. Making multiple sensors redundant, hybrid ToF reduces system costs as well as operation costs, since there are no moving parts that wear out over time.

The solution serves customers with a simplified and user-friendly approach to implementation. The compact hybrid ToF solution is versatile and robust and aligns well with the evolving needs of mobile consumer robot devices in various industries such as robot vacuum cleaners, commercial robots, air-purifiers and size measurement.

Renesas brings industry-leading performance of RA8 series MCUs to motor control applications

Tue, Jan 30, 2024

Renesas has introduced the RA8T1 microcontroller (MCU) group based on the Arm® Cortex®-M85 processor. RA8T1 devices address real-time control of motors, power supplies and other products commonly used in industrial and building automation, as well as smart homes.

The RA8T1 group is the third in Renesas’ RA8 Series, all of which deliver breakthrough performance of 6.39 CoreMark/MHz1. All RA8 MCUs take advantage of the high performance of the Arm Cortex-M85 processor and Arm’s Helium technology that provides up to a 4X performance boost for digital signal processor (DSP) and machine learning (ML) implementations over the Cortex-M7 core. This added performance in RA8T1 devices can be used for AI functions that can predict maintenance requirements for motors, reducing costly downtime.

The new RA8T1 devices include advanced PWM timing features such as 3-phase complementary output, 0% and 100% duty output capability, a double-buffer compare match register, and five phase counting modes. Analog capabilities of the new MCUs include 12-bit ADCs, 12-bit DACs and high-speed comparators used in voltage and current measurement and over-current protection. RA8T1 MCUs also offer multiple communications functions, including SCI, SPI, I2C/I3C, CAN/CAN-FD, Ethernet, and USB-FS. The new group also provides port output shutdown capability when an anomaly is detected, an important safety feature in motor control. These capabilities combined with the advanced timers and Renesas’ power management expertise, enable customers to build comprehensive, low-power motor control solutions.

All RA8 devices also offer advanced security including Arm TrustZone® technology, Renesas Security IP (RSIP-E51A), Secure Boot with first stage bootloader in immutable storage, and Pointer Authentication and Branch Target Identification (PACBTI) security extension.

The new RA8T1 Group MCUs are supported by Renesas’ Flexible Software Package (FSP). The FSP enables faster application development by providing all the infrastructure software needed, including multiple RTOS, BSP, peripheral drivers, middleware, connectivity, networking, and security stacks as well as reference software to build complex AI, motor control and cloud solutions. It allows customers to integrate their own legacy code and choice of RTOS with FSP, thus providing full flexibility in application development. Using the FSP will ease migration of existing designs to the new RA8 Series devices.

The RA8T1 Group MCUs are available now, along with the FSP software. The new MCUs are supported in Renesas’ Flexible Motor Control development kit that enables easy evaluation of motor control using permanent magnet synchronous motors (brushless DC motors), and the Renesas Motor Workbench development tool. This development kit offers a common design platform with numerous Renesas motor control MCUs from the RA and RX families, enabling migration of IP across numerous devices.
