Silicon Labs has launched a new addition to its sub-GHz system-on-chip (SoC) designed to take this sector to broader markets like industrial automation, smart cities and building automation.

Called the FG23L, the SoC is built for long-range and low system cost wireless IoT applications with a combination of +20 dBm transmit power, high receiver sensitivity and ultra-low power consumption, Silicon Labs said.

The SoC integrates a 78 MHz Cortex-M33 core, dual-core wireless architecture and Secure Vault Mid security for compute performance, connectivity and protection against security threats. Other features include:

  • 23 GPIOs
  • Simplicity Studio 5 support
  • Radio Configurator support
  • 10 years of battery life

"The FG23L extends Silicon Labs' proven Sub-GHz leadership into the high-volume, cost-sensitive segment of the market," said Ross Sabolcik, senior vice president of IoT Products at Silicon Labs. "By delivering the best-in-class combination of range, efficiency, and security at the industry's most competitive price-performance, we're enabling customers to bring more connected devices to market faster and at lower cost than ever before."
