Series 2 is built for real-world RF conditions
Silicon Labs Series 2 vs. Closest Competitor
Superior RF sensitivity and selectivity for cleaner performance in noisy environments.
Silicon Labs Series 2 radios deliver a 4.2 dB sensitivity advantage over Closest Competitor devices, enabling longer range and more reliable communication in low-power applications.
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.

Energy efficiency is why our Series 2 devices exists
Longer battery life with better power efficiency
Silicon Labs Series 2 devices deliver high performance without the high price. Compared to Closest Competitor devices, our Series 2 devices consume less power in both typical and sleep modes, enabling multi-year battery life—even in always-on sensing applications.
Our 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.
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.
S e c u r i t y
Built-in Secure Vault
Industry-leading PSA Level 3 and easily updatable
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 Competitor, 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.

Secure, efficient wireless without the price tag
Lower BOM costs with high integration and minimal external components.
Silicon Labs Series 2 devices deliver high performance without the high price. Compared to Closest Competitor parts, you get premium wireless capabilities at a significantly lower BOM cost.
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.
Because the ADC is fully integrated into the device, customers avoid the cost of adding an external component. This lowers BOM cost, keeps our pricing more competitive, and ultimately saves customers money.
