STMicroelectronics 32-Channel Ultrasound Transmitter Suited to Handheld Scanners

　　STMicroelectronics has expanded its family of advanced ultrasound transmitters by adding a 32-channel variant with high output current for portable applications. The new transmitter, STHVUP32, provides ±800mA aimed at portable systems that demand extra drive capability for a coaxial cable-mounted probe.　　Joining the portfolio alongside the 64-channel STHVUP64, the new 32-channel version contains similar features to increase performance and integration in next-generation affordable, high-performing scanners for medical and industrial applications. These include innovations to maximize image quality, built-in digital beam steering, a space-saving driver architecture, and low power consumption.　　The STHVUP32 has 5-level output capability, in addition to the common 3-level output, which enhances flexibility to optimize the picture quality. Its high output current allows driving the scanner’s piezoelectric transducer at high speed to enable multiple imaging modes. It also helps achieve minimum pulse duration of 5ns for superior image detail. The transmitter supports continuous-wave (CW) and pulsed-wave (PW) operating modes to allow various types of analysis including cavities and liquid flow.　　The digital beam steering enhances directional control by permitting greater precision than conventional analog steering using delay circuits. By integrating the beam-steering logic, the transmitter can be used without a companion chip such as an FPGA. This saves PCB space and routing complexity, as well as bypassing FPGA-design challenges.　　Also new, the transmitter has a self-biased driver architecture that saves connecting decoupling capacitors to the transmitter’s power-supply pins. This helps ensure a smaller circuit footprint, as well as lowering the bill of materials (BOM). In addition, the STHVUP32 is housed in a smaller package than comparable alternative ICs thereby helping designers create next-generation products in even smaller form factors.　　While having extremely low power consumption, which is key for battery-operated systems, the STHVUP32 is richly featured for a superior user experience. There is on-chip memory for storing transmission patterns, and synchronization is possible using a clock signal up to 200MHz to enhance image quality by minimizing jitter. The IC also provides a communication port that supports multiple CMOS signaling standards.　　Built-in protection includes noise blocking, thermal protection, under-voltage protection, and recirculating current protection. There is also a diagnostic register that allows directly reading the causes of interrupts to ease debugging in the event of a malfunction.　　The STHVUP32 is built using ST’s proven BCD8s-SOI technology that supports analog (bipolar), digital (CMOS), and power (DMOS) circuits on the same die. It’s in production now, in a 11.5mm x 10.5mm x 1.35mm 168-ball FC-BGA168 package.

RISC-V Summit 2022: All Your CPUs Belong to Us

　　In a recent guest editorial here on EE Times, legendary professor David Patterson wrote about busting the five myths around the RISC-V instruction set architecture (ISA). At the recent RISC-V Summit organized by RISC-V International, the consortium that manages and promotes the RISC-V Instruction Set Architecture (ISA), its president, Calista Redmond, had a far more blunt message: RISC-V is inevitable.　　In fact, she said, RISC-V will eventually have the best CPUs, the best software running on them and the best ecosystem of any microprocessor core family. These are mighty strong words for a nascent ISA that is only about 10 years old and that competes with the far more established Arm and x86 ISAs. It almost sounded like the Borg from Star Trek when they say, “Resistance is futile.”　　RISC-V International CEO Calista Redmond (Source: RISC-V International)　　Redmond’s reason for saying that RISC-V is inevitable is that its growth and success are built upon shared investments of many companies, universities and contributors. RISC-V International has more than 3180 members. Billions of dollars have been invested in the architecture, including national programs from countries and regions such as India and the E.U. This enables the development of the “best” processor in multiple price and performance categories with the contributions of so many ideas and collective knowledge. Because RISC-V is scalable, customizable and modular, it can easily be optimized for different workloads and applications.　　The software ecosystem is growing, and efforts are underway to make software development more efficient with profiles and standards like a single hypervisor standard.　　RISC-V origins　　RISC-V is an open specification like Ethernet. It was developed at University of California, Berkeley (UC Berkeley) with a clean-slate approach to RISC (reduced instruction set computer) designs. There had been many RISC ISAs in the past: 29K, Alpha, Arm, i960, MIPS, PowerPC and SPARC to name some. All those other RISC architectures have been tied to a corporate owner, and most have become outdated.　　The researchers at UC Berkley felt it was time for a clean slate with no corporate owners, initially for educational use, but they soon recognized it was useful for more than instructional purposes.　　With this approach, multiple companies can build CPUs using the open standard. This means that there are many different options to get RISC-V CPUs, and there are more every year. You can download the specifications and design your own CPU. You can download open-source versions of RISC-V CPUs. You can buy a CPU core from multiple IP vendors. You can get a customized CPU core from other vendors. You can buy chiplets with RISC-V cores. You can buy a chip with an RISC-V processor. Or you can buy a full AI chip running with RISC-V cores.

Global Handset ASP Increase Limits 3Q 2022 Revenue Decline to 3% YoY

　　The record shipment contribution (46%) of 5G handsets, which cost five times an average non-5G handset, added to the global smartphone ASP and revenue growth.　　The global smartphone handset market’s revenue declined by 3% year-on-year (YoY) in the third quarter (3Q 2022) to just above $100 billion, according to the latest research from Counterpoint Technology Market Research’s Market Monitor Service. A 10% YoY growth was seen in the average selling price (ASP) thanks to the premium handset segment’s greater resilience to economic uncertainty.　　The record shipment contribution (46%) of 5G handsets, which cost five times an average non-5G handset, also added to the ASP and revenue growth. In terms of shipments, the overall handset market saw a 12% YoY decline during the quarter.　　“At over $80 billion, the revenue contribution of 5G handsets reached an all-time high of 80% of global handset revenues, up from 69% in the third quarter of last year. In the same period, LTE handsets’ revenue contribution fell 10% to $19 billion. This shift from 4G to 5G has been led by Apple, which alone makes up for over half of all 5G revenues as over 95% of its phones are 5G-enabled. Apple saw a 10% YoY revenue growth and 7% YoY ASP growth in Q3 2022, contributing to an overall increase in global handset ASP. This is thanks in part to the launch of the iPhone 14 series as well as the Pro models, especially from the previous generation, doing well,” Senior Analyst Harmeet Singh Walia said.　　Samsung, the second biggest handset OEM in terms of revenue, saw a relatively modest ASP increase of 2% YoY in Q3 2022 despite an almost doubling of the shipments of its premium Flip and Fold series in the same period as well as a 27% YoY revenue growth of its 5G smartphones. The lower growth of its ASP can be attributed to a shift in its focus from the more successful S22 series to the still upcoming foldable series. Consequently, Samsung’s revenue declined 4% YoY in Q3 2022.　　Xiaomi’s handset revenue grew 4% YoY, a significant portion of which came from the low-to-mid price bands. The shipment share of the over-$300 price band declined by close to 1.5%. There was, however, a significant shift from the sub-$200 to $200-$299 price band. Consequently, Xiaomi’s ASP grew 14% YoY to $205.　　OPPO, on the other hand, saw an ASP as well as a revenue decline of 5% and 27% YoY respectively. The revenue decline was primarily caused by OPPO’s shipment decline in COVID-hit China, which contributed over 40% to its total shipments in Q3 2022. Given that China contributed over half of vivo’s total shipments, its revenue took an even bigger hit of 43% YoY despite growing 4% QoQ.

Quick Charge 4 is designed to provide a superior charging solution by delivering up to 50% power charge in roughly 15 minutes or less (Qualcomm notes that actual results may vary depending on device design). With these new features incorporated into a device and the charger, Quick Charge 4+ can charge up to 15% faster or 30% more efficiently than Quick Charge 4.Through further advancements in the method for delivering power, Qualcomm says mobile devices that employ Quick Charge with Dual Charge technology can reach up to 97% efficiency, which translates to less power being lost during the charging process, energy savings and reduction of the heat generated within the device. Additionally, Quick Charge 4+ now incorporates a new battery sensing technology that directly measures the voltage of the battery cell and allows the system to have a more accurate view of the battery’s current state, so they can stay in high current charging for longer, in order to further reduce charge times.Quick Charge 4+ also supports USB Power Delivery (USB PD) as its primary signaling method, allowing it to offer a “one charging solution for all” experience. This means that chargers equipped with Quick Charge 4+ are designed to enable devices to be charged with or without Quick Charge technology or Qualcomm Snapdragon architecture inside them.

Qualcomm 4G/5G Summit:Creating headsets with Alexa

Qualcomm has announced what it says is the industry’s first qualified, end-to-end, Bluetooth, Smart Headset reference design featuring push-button activation support for Alexa for users of Android phones with the Alexa app.Based on Qualcomm family of Bluetooth audio chips (QCC5100-series), the company says the reference design includes virtually all the key hardware and software required for manufacturers to help them develop advanced Bluetooth headsets more efficiently and cost-effectively. In addition to support for Alexa, the solution also supports ultra-low power consumption for extended playback time and battery life, as well as Qualcomm cVc noise reduction technology designed for superior audio and voice service capabilities. Manufacturers can also add support for active noise cancellation and Qualcomm aptX HD high-resolution wireless audio.The Qualcomm Smart Headset Development Kit is the first Bluetooth Smart Headset reference design built with support for the Alexa Mobile Accessory Kit, a protocol that runs over Bluetooth, and is designed to allow users to easily connect Bluetooth-enabled audio devices with Alexa via the Alexa app. This means device makers no longer need to oversee the bulk of coding for their Alexa integration or to add any communication hardware beyond Bluetooth, which helps to reduce cost and accelerates development time.“Our consumer research shows that four out of five consumers have embraced voice services, but the vast majority are also looking for superb audio quality. The Qualcomm Smart Headset reference design brings this and more together, helping consumers to take advantage of Alexa on-the-go, without the need to interact with their phone,” said Anthony Murray, senior vice president and general manager, voice & music, Qualcomm.The QCC5100-series SoC architecture is designed to deliver low-power consumption and optimised to ensure longer audio playback time for both voice calls and music streaming. A dedicated application processor sub-system, dual DSP architecture and next-generation audio development kit software provide a powerful foundation for the development of highly differentiated audio products. The SoC family is also engineered to support concurrent software operation, meaning that users can transition smoothly between functions such as listening to music, making calls, running biometric sensors and using voice services. Qualcomm cVc noise reduction technology helps to deliver accurate speech recognition even in very challenging acoustic environments, as well as to provide crisp voice communication for both parties in a phone call.The Qualcomm Smart Headset reference design with Alexa is available now. Customers can use the reference design to help them evaluate building Alexa on-the-go experiences and can step up and begin development with a suite of software and tools to customise or develop their own headset products. For more information and to get started building with Qualcomm.
