EFR32ZG23B021F512IM40-B

Product Overview

EFR32ZG23B021F512IM40-B is an RF transceiver SoC with integrated microcontroller from Silicon Labs. The device combines radio communication and embedded control in one package, making it useful when the wireless protocol stack and local application processing need to sit close together. It is typically reviewed for sub-GHz ISM connectivity and for products such as sub-GHz ISM telemetry, remote control, metering, security and industrial wireless products.

For design-in or replacement, buyers should confirm the orderable version is associated with a 40-VFQFN Exposed Pad package, surface-mount IC package for compact RF PCB layouts. The antenna path, matching network, firmware or protocol stack, regulatory requirements and lifecycle status should also be checked against the official manufacturer documentation before production use.
