Analisi comparativa ai SoC wireless di Silicon Labs Jul 07, 2022

Silicon Labs è stato attivo nel SoC wireless ultimamente. Ha lanciato EFR32FG23 (FG23) nel settembre 2021 e ha rilasciato EFR32BG24 (BG24) ed EFR32MG24 (MG24) nel gennaio 2022. Tutti hanno superato la convalida nei client alfa e sono ora pronti per la spedizione nel mercato aperto.

xFG23 è stato creato per bande sub 1GHz, supporta Wi-SUN e protocolli proprietari . Si tratta delle prime soluzioni wireless sub-GHz al mondo che combinano RF a lungo raggio ed efficienza energetica con sicurezza Arm PSA Level 3 certificata.

xBG24 e xMG24 sono stati costruiti per una frequenza di 2,4 GHz. Mentre entrambi supportano l'accelerazione AI/ML sul lato edge, xBG24 supporta Bluetooth e 2,4 GHz proprietari e xMG24 è il primo SoC wireless Matter-Ready di Silicon Lab. Quest'ultimo estende la funzione multiprotocollo all'estremo incorporando Bluetooth, 2,4 GHz proprietario, Matter, Zigbee e Thread, facilitando agli utenti la creazione di applicazioni IoT interconnesse e interoperabili.

È normale che i nuovi prodotti vengano forniti con aggiornamenti nella configurazione o nelle prestazioni, ecc. Tuttavia, in scenari reali di creazione di applicazioni IoT, è necessario esaminare e scambiare più elementi. A tale scopo, RF-star ha effettuato un'analisi comparativa di tutti i SoC wireless di Silicon Labs nella tabella seguente come riferimento.
