Silicon Labs Series 2 vs. Closest Competitor
p e r f o r m a n c e
Series 2 is built for real-world RF conditions
Silicon Labs Series 2 radios deliver a significant sensitivity advantage over the closest competitors devices, enabling longer range and more reliable communication in low-power applications.
p o w e r C o n s u m p t i o n
Energy efficiency is why our Series 2 devices exist
Silicon Labs Series 2 devices consume less power in both typical and sleep modes than the closest competitor, enabling multi-year battery life—even in always-on sensing applications.
S e c u r i t y
Built-in Secure Vault
Series 2 delivers PSA Level 3 certification, secure key storage, and in-field update capabilities—far beyond the fixed-function security in closest competitor devices. If a vulnerability is found in closest competitors devices, it's incredibly difficult to patch.
Your engineering team doesn’t need to become security experts just to meet regulations. Secure Vault takes care of PSA compliance, key management, and tamper protection out of the box — no TrustZone setup required. You focus on innovation. We’ll handle the attack surface.
p r i c e
Secure, efficient wireless without the price tag
Silicon Labs Series 2 devices deliver high performance without the high price. Compared to the closest competitor's parts, you get premium wireless capabilities at a significantly lower cost.

Silicon Labs Set the standard for Connected Intelligence.
Series 2 also wins in the following areas:
Coexistence for Crowded Environments
With advanced multiprotocol capabilities and dedicated hardware for dynamic coexistence management, Series 2 devices maintain robust connections even alongside heavy Wi-Fi, Bluetooth, or Thread traffic. Unlike the closest competitors series, which requires more tuning and lacks comparable real-time interference mitigation, Silicon Labs offers proven coexistence performance with minimal packet loss and reduced latency.
We did the hard work so you don't have to.
Built for Always-On Devices
Our hardware accelerator eliminates the traditional CPU bottleneck by delivering machine learning performance that’s 4x faster and 6x more energy efficient. Purpose-built for always-on devices, MVP enables continuous ML processing—from voice wake word detection to vibration-based predictive maintenance—without taxing the battery or the CPU. By pushing intelligence to the edge, accelerator helps embedded systems operate longer.
Accurate Battery Life Built Into the xG27 and XG29
Silicon Labs SoCs feature integrated battery monitoring with a built-in coulomb counter, eliminating the need for an external PMIC and saving over $0.50 per device. This on-chip solution enables accurate, real-time battery tracking, ensuring precise low-battery alerts and consistent operation during critical tasks—essential in medical, industrial, and safety-critical applications where voltage-based estimates often fall short.
Capture What Others Miss: 20-bit ADC Precision for Smarter, Safer Devices
Silicon Labs’ SoCs deliver precision with high-accuracy ADCs that enable smarter, safer designs. The xG24 features a 20-bit ADC that detects voltage changes as small as 3 µV—over 30× finer than a standard 14-bit ADC. The xG22, xG27, and xG29 offer 16-bit ADCs that resolve down to 50 µV. This granularity helps detect battery imbalances, track shunt voltages, and capture biosignals like ECG or PPG.
Design for Any Battery Chemistry
Select Silicon Labs’ SoCs support any battery chemistry with an integrated DC-DC boost that operates from just 0.8 V—far lower than competitors that shut down below 1.7 V. That means no need for an external $0.20+ boost IC and full support for alkaline, silver-oxide, and zinc-air cells. Power your Bluetooth product with a single 1.5 V cell for thinner, lighter designs without sacrificing performance.
Introducing the Series 3 Portfolio: A New Era of IoT Performance
Silicon Labs' newly launched Series 3 portfolio sets a new standard for compute power, integration, security, and energy efficiency—meeting the demands of today’s line- and battery-powered IoT devices.
As smart devices become more compact and capable, the need for robust, secure, and integrated wireless solutions is greater than ever. Series 3 SoCs rise to the challenge with advanced processing, flexible memory, top-tier security, and simplified external component integration.
Together Series 2 and the Series 3 platform expands our IoT leadership—delivering scalable solutions for the full spectrum of applications.
