EFR32SG28 Dual-Band System-on-Chips (SoCs)

Silicon Labs EFR32SG28 Dual-Band System-on-Chips (SoCs) are designed specifically for Amazon's Sidewalk ecosystem. The high-performance, dual-band devices support multiple Sidewalk PHYs, including 2.4GHz BLUETOOTH® Low Energy for in-home connectivity and sub-GHz FSK for "beyond the fence" and Neighborhood Area Networks. The Silicon Labs EFR32SG28 single-die, multi-core solution provides industry-leading security, low power consumption with fast wakeup times, and integrated power amplifiers to enable the next level of secure connectivity for Amazon Sidewalk devices. Key features, including a large memory footprint, an AI/ML hardware accelerator, Secure Vault®, and up to 49 GPIO, enable Silicon Labs' most feature-rich product for Amazon Sidewalk applications.
