  • Ultra-low standby current with full 288KB SRAM retention and RTC operation that enables significant battery life extension, especially for applications with longer sleep intervals
  • Extended temperature support with very low standby current
  • Integrated balun and integrated RF switch to support both transmit and receive operations on the same RF pin, even at +20dBm transmit power; thereby, enabling a reduced bill-of-material (BOM) board layout
  • Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth Low Energy and IEEE 802.15.4

The CC2755x20 devices are part of the SimpleLink™ MCU platform, which consists of Wi-Fi, Bluetooth Low Energy, Thread, Zigbee, Sub1GHz MCUs, and host MCUs that all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich toolset. A one-time integration of the SimpleLink™ platform enables you to add any combination of the portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change.
