Software for Real-Time C2000 MCUs Reduces Design Complexities
Texas Instruments (TI) has introduced DesignDRIVE Fast Current Loop software that

makes C2000 microcontrollers the first devices to push current-loop performance to less than 1 microsecond, according to TI. Together, TI's C2000 MCU portfolio and DesignDRIVE software delivers system-on-chip (SOC) functionality which simplifies drive control system development. New DesignDRIVE Fast Current Loop software outperforms traditional microcontroller (MCU)-based current-loop solutions and can simplify designs by eliminating the field-programmable gate array (FPGA) typically used for external current-loop control. Fast Current Loop software is a free update available for C2000 controlSUITE software. CONTINUE READING NXP and Widex Team for Wireless Audio Streaming Hearing Aids
NXP Semiconductors and Widex announced that they have collaborated to develop, test and integrate NXP's NxH2003 Bluetooth Low Energy

(BLE) audio streaming SoC into Widex BEYOND hearing aids. The two companies worked closely together throughout the product development cycle, merging the best of hearing aid engineering and wireless audio streaming semiconductor technology, to deliver hearing aid devices that can stream wireless audio from an iOS device, consuming only 2.8 mA current at 1.2 Volts, which is currently the best in the industry. This allows users to enjoy music directly from their personal devices for prolonged periods of time. CONTINUE READING
Renesas Expands Support for HMI Development with RZ/G MPUs

Renesas has expanded its RZ microprocessor (MPU) Family to support the growing range of human-machine interface (HMI)- and vision-based systems, with performance scalability from entry-level to highly complex embedded applications. The new RZ/G1C MPUs from the Renesas RZ/G Series enable rapid development of high-performance HMI applications and support 3D graphics with full high-definition (FHD) video. The RZ/G1C is specially optimized for Linux-based application development. The Renesas RZ/G MPU Series lets system manufacturers right-size their processor selection to support current and next-generation connected devices, ranging from home appliances with touch-based displays to industrial equipment with integrated embedded vision-equipped HMI that enables image recognition and artificial intelligence.

Check Out These New White Papers! Coding standards are proven to improve code quality, but without automation, they are difficult to enforce and may be ignored by developers. Download this white paper to learn how to create a coding standard from existing resources and use a static analyzer to ensure it is followed by your developers. - "Automating Coding Standards"
Security vulnerabilities can put users at risk and damage companies' reputations, and these risks increase as more devices are connected to the internet. Download this white paper to learn how to choose and enforce the best coding standard for your application to reduce these risks. - "How to Choose the Right Coding Standard for Embedded Software Security" GET THE FREE WHITE PAPERS

Microchip Sequential Linear LED Driver Targets Offline Lighting
A next-generation sequential linear LED driver for offline lighting applications is now available from Microchip Technology. The

CL88020, an extension of Microchip's CL88XX family, is designed to drive a long string of low-cost LEDs directly from the 120 VAC line input. The product allows customers to create reliable, cost-effective and compact LED lighting applications by having High Power Factor (PF) without the need for switch-mode power conversion which is typically required for LED lighting design. The CL88020 was designed to minimize driver circuit component count to allow for a very small and efficient design. The simple design allows for a single-layered Printed Circuit Board (PCB) design. Unlike the conventional AC-DC switch mode power supply, the basic driver circuit consists of the CL88020 IC, two small ceramic capacitors and a bridge rectifier only. High-voltage capacitors, transformers or inductors, electromagnetic interference (EMI) filters or Power Factor Correction (PFC) circuitry are not required. This allows for a smaller solution size and a lower overall bill of material (BOM) cost as compared to traditional LED solutions. CONTINUE READING
BLE Chip from STMicroelectronics Targets Connected Smart Things
A new-generation Bluetooth Low Energy (BLE) System-on-Chip from STMicroelectronics is aimed at accelerating the spread of connected smart objects throughout homes, shopping areas, industry, toys, gaming, personal healthcare,

and infrastructure. ST sees important opportunities for BLE-connected applications that are simple, functionally focused, and can operate on a button cell for months or even years. The new BlueNRG-2 chip meets all these needs with its extremely power-efficient programmable processor and low-power features, including an ultra-frugal standby mode. The high RF signal strength saves system power by ensuring reliable wireless communication, generous on-chip memory for BLE software, and the application code simplifies system design by saving external memory components. BlueNRG-2 is Bluetooth 5.0-certified, which ensures interoperability with the latest generation of smartphones. It also supports enhanced features such as state-of-the-art security, privacy, and extended packet length for faster data transfer. CONTINUE READING
