Cypress Semiconductor has announced its Wi-Fi and Bluetooth combo solution is used on the new Raspberry Pi 3 Model B+ IoT single board computer. The Cypress CYW43455 single-chip combo provides high-performance 802.11ac Wi-Fi for faster Internet connections, advanced coexistence algorithms for simultaneous Bluetooth and Bluetooth Low Energy (BLE) operations such as audio and video streaming, and low-power BLE connections to smartphones, sensors and Bluetooth Mesh networks. The combo’s high-speed 802.11ac transmissions enable superior network performance, faster downloads and better range, as well as lower power consumption by quickly exploiting deep sleep modes. The Raspberry Pi 3 Model B+ board builds on the success of existing Raspberry Pi solutions using Cypress’ CYW43438 802.11n Wi-Fi and Bluetooth combo SoC.

Wi-Fi networks powered by 802.11ac simultaneously deliver low-latency and high-speed with secure device communication, making it the ideal wireless technology for connecting products directly to the cloud. The Raspberry Pi 3 Model B+ board with the highly-integrated Cypress CYW43455 combo SoC allows developers to quickly prototype industrial IoT systems and smart home products that leverage the benefits of 802.11ac.

The Raspberry Pi 3 Model B+ board features a 64-bit, quad-core processor running at 1.4 GHz, 1 GB RAM, full size HDMI, 4 standard USB ports, Gbit Ethernet over USB2, Power over Ethernet capability, CSI camera connector and a DSI display connector. The platform’s resources, together with its 802.11ac wireless LAN and Bluetooth/BLE wireless connectivity, provide a compact solution for intelligent edge-connected devices.

The Cypress CYW43455 SoC features a dual-band 2.4- and 5-GHz radio with 20-, 40- and 80-MHz channels with up to 433 Mbps performance. This fast 802.11ac throughput allows devices to get on and off of the network more quickly, preventing network congestion and prolonging battery life by letting devices spend more time in deep sleep modes. The SoC includes Linux open source Full Media Access Control (FMAC) driver support with enterprise and industrial features enabled, including security, roaming, voice and locationing.

Cypress’ CYW43455 SoC and other solutions support Bluetooth Mesh networks—low-cost, low-power mesh network of devices that can communicate with each other, and with smartphones, tablets and voice-controlled home assistants, via simple, secure and ubiquitous Bluetooth connectivity. Bluetooth Mesh enables battery-powered devices within the network to communicate with each other to easily provide coverage throughout even the largest homes, allowing a user to conveniently control all of the devices from the palm of their hand. The SoC is also supported in Cypress’ all-inclusive, turnkey Wireless Internet Connectivity for Embedded Devices (WICED) software development kit (SDK), which streamlines the integration of wireless technologies for IoT developers.

Linux and Coming Full Circle

Input Voltage

–Jeff Child, Editor-in-Chief

In terms of technology, the line between embedded computing and IT/desktop computing has always been a moving target. Certainty the computing power in small embedded devices today have vastly more compute muscle than even a server of 15 years ago. While there’s many ways to look at that phenomena, it’s interesting to look at it through the lens of Linux. The quick rise in the popularity of Linux in the 90s happened on the server/IT side pretty much simultaneously with the embrace of Linux in the embedded market.

I’ve talked before in this column about the embedded Linux start-up bubble of the late 90s. That’s when a number of start-ups emerged as “embedded Linux” companies. It was a new business model for our industry, because Linux is a free, open-source OS. As a result, these companies didn’t sell Linux, but rather provided services to help customers create and support implementations of open-source Linux. This market disruption spurred the established embedded RTOS vendors to push back. Like most embedded technology journalists back then, I loved having a conflict to cover. There were spirited debates on the “Linux vs. RTOS topic” on conference panels and in articles of time—and I enjoyed participating in both.

It’s amusing to me to remember that Wind River at the time was the most vocal anti-Linux voice of the day. Fast forward to today and there’s a double irony. Most of those embedded Linux startups are long gone. And yet, most major OS vendors offer full-blown embedded Linux support alongside their RTOS offerings. In fact, in a research report released in January by VDC Research, Wind River was named as the market leader in the global embedded software market for both its RTOS and commercial Linux segments.

According the VDC report, global unit shipments of IoT and embedded OSs, including free/non-commercial OSs, will grow to reach 11.1 billion units by 2021, driven primarily by ECU-targeted RTOS shipments in the automotive market, and free Linux installs on higher-resource systems. After accounting for systems with no OS, bare-metal OS, or an in-house developed OS, the total yearly units shipped will grow beyond 17 billion units in 2021 according to the report. VDC research findings also predict that unit growth will be driven primarily by free and low-cost operating systems such as Amazon FreeRTOS, Express Logic ThreadX and Mentor Graphics Nucleus on constrained devices, along with free, open source Linux distributions for resource-rich embedded systems.

Shifting gears, let me indulge myself by talking about some recent Circuit Cellar news—though still on the Linux theme. Circuit Cellar has formed a strategic partnership with LinuxGizmos.com. LinuxGizmos is a well-establish, trusted website that provides up-to-the-minute, detailed and insightful coverage of the latest developer- and maker-friendly, embedded oriented chips, modules, boards, small systems and IoT devices—and the software technologies that make them tick. As its name in implies, LinuxGizmos features coverage of open source, high-level operating systems including Linux and its derivatives (such as Android), as well as lower-level software platforms such as OpenWRT and FreeRTOS.

LinuxGizmos.com was founded by Rick Lehrbaum—but that’s only the latest of his accolades. I know Rick from way back when I first started writing about embedded computing in 1990. Most people in the embedded computing industry remember him as the “Father of PC/104.” Rick co-founded Ampro Computers in 1983 (now part of ADLINK), authored the PC/104 standard and founded the PC/104 Consortium in 1991, created LinuxDevices.com in 1999 and guided the formation of the Embedded Linux Consortium in 2000. In 2003, he launched LinuxGizmos.com to fill the void created when LinuxDevices was retired by Quinstreet Media.

Bringing things full circle, Rick says he’s long been a fan of Circuit Cellar, and even wrote a series of articles about PC/104 technology for it in the late 90s. I’m thrilled to be teaming up with LinuxGizmos.com and am looking forward to combing our strengths to better serve you.
