Becoming a member of Silicon Labs’ sub-GHz wi-fi SoC household, the FG23L delivers safe long-range connectivity for resource-constrained IoT gadgets. Its hyperlink funds of ~146 dB and transmit energy of +20 dBm present as much as twice the vary of comparable gadgets. By balancing efficiency and affordability, the SoC broadens sub-GHz adoption throughout markets from industrial automation and sensible metropolis infrastructure to agriculture IoT and linked properties.
The FG23L runs on a 78-MHz Arm Cortex-M33 with DSP extensions and an FPU for environment friendly sign processing. It contains 128 KB of flash and 32 KB of RAM to assist utility and knowledge storage. The low-power radio core spans the complete vary of license-free sub-GHz ISM bands (110 MHz to 970 MHz). Energetic and sleep currents of 36 µA/MHz and 1.2 µA, respectively, allow over 10 years of battery life.
Midlevel Safe Vault safeguards the communication channel and defends in opposition to logical assault vectors. Safety features embrace a real random quantity generator, crypto engine, safe utility boot, and safe debug lock/unlock.
The FG23L can be usually accessible on September 30, 2025. Developer kits can be found now.
The submit SoC extends IoT vary with environment friendly sub-GHz radio appeared first on EDN.
