In stock at distributor Mouser Electronics are the  MG24 and BG24 Series 2 wireless system-on-chip (SoC) devices from Silicon Labs.

Featuring 2.4 GHz RF, low-power consumption, and an AI/ML hardware accelerator, the wireless SoCs offer an ideal solution for mesh Internet of Things (IoT) wireless connectivity using Matter, OpenThread, and Zigbee protocols.

The new wireless SoCs support a range of smart home, lighting, and building automation applications, including gateways and hubs, sensors, location services, and predictive maintenance.

The Silicon Labs EFR32MG24 wireless SoCs, feature an Arm Cortex-M33 microcontroller offering up to 78 MHz, 1.5 Mbytes of Flash, and 256 Kbytes of RAM.

They offer exceptional energy efficiency and AI/ML hardware accelerator ensure reliable performance for the present and future of IoT device design.

There is an extensive collection of MCU peripherals, including two digital-to-analogue converters, up to 32 general-purpose I/O pins with output state retention and asynchronous interrupts, two 32-bit timer/counters with three compare/capture/PWM channels, and two 32-bit real-time counters.

The Series 2 wireless SoCs offer robust performance, boasting an operating temperature range of -40°C to +125°C.

The EFR32BG24 wireless SoCs feature Bluetooth Low Energy (BLE 5.3) and Bluetooth Mesh connectivity, exceptional low-power wireless performance, and extensive security capabilities.

Low system energy consumption offers 4.4 mA RX current, 5 mA TX current @ 0 dBm output power, 19.1 mA TX current @ 10 dBm output power, and 156.8 mA TX current @ 19.5 dBm output power.

The SoCs’ security features include hardware cryptographic acceleration, secure debug unlock, true random number generator, and secure key management with PUF.
