Silicon Labs stock has been on a tear lately. Since the end of March, it has been up 44%. If you are not familiar with Silicon Labs, it is a global, fabless semiconductor company headquartered in Austin, TX, my hometown. The company’s HQ is so close in proximity to my home and office, and I can see its logo. While the company does as much in the industrial IoT, you’ve likely used a consumer IoT device with Silicon Labs inside. Silicon Labs’ silicon is inside the Amazon Echo, Nest smart thermostat, a Fitbit, Google OnHub, Zigbee smart lightbulbs, Samsung Connect, and Tesla electric vehicles.
The company designs silicon devices, software, platforms, and semiconductors for various markets, including the Internet of Things (IoT), industrial automation, consumer, and automotive markets. Although Silicon Labs touches many markets, a large portion of the company’s focus is building processors and software to support devices within the Internet of Things (IoT). The company doesn’t manufacture its own devices but instead relies on foundries like TSMC for manufacturing. With silicon, security, developer tools, plus an ability to support over 100 wireless protocols and make them all work together, Silicon Labs has quietly become the backbone of IoT and occupies a space no other company can quite match right now.
Works With developer conference
On September 9th and 10th, Silicon Labs hosted its first “Works With” conferencefocused on smart home developers. The event included keynotes, panels, hands-on workshops, one-on-one developer meetings, specialized educational sessions, and technical training for developers designing smart home devices across major ecosystems, including Amazon, Google, Comcast, and others. The virtual live-stream was free to watch, and thousands of developers, engineers, and product managers were in attendance. If you missed it, you could catch on-demand replays on the conference website.
Silicon Labs CEO Tyson Tuttle (bio) and Matt Johnson, IoT SVP and GM (bio), led the event. Keynote speakers included some IoT industry juggernauts with executives from Amazon (Josh Danovitz), Google (Grant Erickson), Comcast (Jim Kitchen), and more from Silicon Labs. Ring CEO and founder Jamie Siminoff delivered an inspiring day two keynote. To my knowledge, the event is one of, if not the first, silicon event focused solely on smart home developers. Silicon Labs took full advantage of its audience by launching some new Bluetooth tech, IoT security suites, and new multiprotocol wireless developer software tools during the event. I wanted to cover that below.
New Bluetooth Low Energy Devices
Silicon Labs has a successful history of selling low power, low cost, and high-performance Bluetooth 5.2 system-on-chip (SoC), system-in-package (SiP), modules, and Network Co-processors (NCP). Its SoCs are better suited for IoT device makers that need more flexibility and customizable software and radio frequency design options. SiP modules serve a different audience looking for a smaller form factor device with little radio frequency or engineering work required for successful implementation.
The first announcement I want to touch on is Silicon Labs expansion in its Bluetooth Low Energy portfolio by launching the BGM220S. The BGM220S is one of the world’s smallest Bluetooth SiPs measuring just 6×6 mm, and it will be supplying Bluetooth connectivity to tiny IoT devices. The company also launched the BGM220P, a slightly more considerable variation of the BGM220S with better wireless performance and range. These devices support Bluetooth Direction Finding while offering up to ten years of battery life on a single coin cell. There is plenty of demand for low energy Bluetooth devices, and I believe Silicon Labs has a competitive Bluetooth offering for IoT manufacturers.
In fact, in the company’s Q2 earnings call, Tyson Tuttle advised that the company’s BG22 Secure Bluetooth 5.2 SoCs are experiencing among the highest levels of product adoption and opportunity pipeline growth of any product Silicon Labs has ever launched. The BG22 launched during CES 2020. In that same Q2 earnings call, Tuttle said that BG22 is responsible for over $1 billion in new opportunities across a wide range of applications in consumer, medical and smart home applications. Pretty impressive, and something to keep an eye on.
New Secure Vault
Also new from Silicon Labs is its Secure Vault security suite, explicitly designed to secure IoT devices and ensure it comply with data privacy and security regulations. Secure Vault is a new suite of security features designed for IoT device manufacturers to protect its brand, product designs, and consumer data. The features address dynamic IoT security threats, which continue to grow and evolve as wireless edge devices proliferate. Silicon Labs’ Wireless Gecko Series 2, small form factor SoCs use Secure Vault security features to keep IoT devices secure. It combines several security features like secure boot based on a hardware root of trust, secure debug, physical tamper, secure identity for attestation, and physically unclonable function (PUF) to provide a safe IoT experience. In today’s complex environment, it is crucially essential for devices to secure by design. As attack vectors change and grow in complexity, silicon manufacturers must be proactive in designing security features.
“Threats are continuously evolving, and the demands on IoT product developers to keep up can be difficult – particularly in low cost, resource-constrained IoT products,” said Matt Johnson, senior vice president of IoT at Silicon Labs.
Secure Vault is available in Silicon Labs’ new EFR32MG21B multiprotocol SOCs. The EFR32MG21B received PSA Certified Level 2 certification and was the first radio to receive that certification level. PSA Certified Level 2 certification built on an assurance framework cofounded by Arm, helps drive security standards and speeds up a time to market. Silicon Labs understands that security needs to built-in at the silicon level.
Updated Simplicity Studio IoT Developer Environment
Silicon Labs announced a major new update of its Simplicity Studio developer tools at the “Works With” conference. For those that are not familiar with Simplicity Studio, Silicon Labs created a development environment to support its IoT portfolio of modules and SoCs. There are plenty of technical and business challenges that IoT developers face ranging from optimizing for performance, power, and security to meeting timelines, certifications, and code reuse. The real value of the Simplicity Studio software is to simplify a developer’s workflows while running in conjunction with the developer’s unique environment.
Silicon Lab integrated feedback from customers and users to redesign and retool Simplicity Studio for better user experience. The main upgrades from Simplicity Studio 4 to the new Simplicity Studio 5 include a new modern user interface, debug and analysis capabilities, workflow optimizations, and a performance uplift from last gen. The software will recognize the evaluation and development kits created by Silicon Labs. After that recognition, the software then automatically suggests SDKs, tools, and resources for that user. The application is also free to use.
Silicon Labs put together some Simplicity Studio 5 highlights that I listed below.
- Scalable: one tool and one environment featuring multiple protocols; support for additional protocols will be continuously added. This includes support for OpenThread, making it simpler to develop IPv6 based mesh applications and paving the way for the future development of Project Connected Home over IP-based devices running on Silicon Labs’ EFR32 Wireless Gecko.
- Responsive User Interface (UI): completely new web-like user interface.
- Modern Platform: based on the latest versions of the C/C++ development tooling and the open-source Eclipse platform, enabling Eclipse Marketplace plug-ins to use.
- Core Improvements: improved performance and industry-standard code editors, compilers, and debuggers.
- Network Analyzer: simplifies the development of mesh network solutions by collating results across the network.
- Project Configuration: new project tools enabled through software component-based SDKs add enhanced levels of software component discoverability, configurability, and dependency management that surpasses competitor tools.
- Power Profiler: analyzes total power consumption in a device to optimize the design and extend battery life.
- Advanced Security: enables state-of-the-art Secure Vault features to help future proof IoT devices against escalating threats and regulatory requirements.
- Automatic Board Detection: automatically locates device-specific technical documentation and software examples once the board is connected.
- Value-add Tools: code-correlated energy profiling, wireless network analysis, and improved debugging to speed time to market of advanced applications.
A few minutes with CEO Tyson Tuttle
I got the chance to spend a few minutes with Silicon Labs’ CEO Tyson Tuttle (bio) after day one of its “Works With” conference. I asked Tyson about the short-term goals of the company within the next 12 months. He responded that Silicon Labs wants to come out of the pandemic with sustained momentum and fully prepared for a rapid growth path in the IoT space. The Covid-19 pandemic has accelerated the connected device trend need for security, privacy, convenience, and automation.
Tyson’s goal for Silicon Labs is to be recognized for its IoT connectivity leadership and be the clear go-to \partner for companies implementing these solutions. As the number of IoT devices and endpoints continue to grow, the need for a single chip, fully integrated low power and low-cost wireless solutions will rise. Thankfully, those devices are in Silicon Labs’ wheelhouse. Silicon Labs no longer looks like a hardware company but instead seems to be a focused systems company committed to long term IoT execution.
I am struck by how many different protocols the company supports across so many IoT platforms and chips; therefore, the company looks like a low-risk path for ODM and OEMs. Also, I am impressed that the company is creating full platforms, including RDKs, SDKs, and tools, to develop real products with a faster time to market.
Silicon Labs packed a lot of meaningful content and announcements into the company first “Works With” smart home developer conference. If you’re an IoT device developer, Silicon Labs is going above and beyond by providing training and free software resources like Simplicity Studio 5 to increase developer effectiveness and get your products to market faster.
Silicon Labs is focused on long term growth within the IoT consumer, commercial and industrial markets. The only way to do that is to be the chip that powers and connects as many IoT devices as possible. The “Works With” conference was a strong showing for Silicon Labs in the home IoT space, and for that, I applaud them.
