EFR32SG23B020F512IM40

EFR32SG23 Series 2 SoCs

The EFR32SG23B020F512IM40 is a secure, low power wireless SoC for Amazon Sidewalk devices that supports sub-GHz FSK, providing reliable range beyond the front door to cover detached buildings, pools, and spas. The multi-core device has efficient ARM Cortex®-M33 running up to 78 MHz and with 512 kB of Flash and 64 kB of RAM. The low active and sleep currents make it ideal for battery operated end devices like sensors including door, window, and temperature sensors devices, while the link budget of 129.5 dBm provides long range and reliable communication. The dedicated security core supports our Secure Vault™ High, bringing industry leading IoT security to the device to protect wireless data and the device from both remote and local attacks.
