The SimpleLink™ CC2340R5 device is a 2.4 GHz wireless microcontroller (MCU) targeting Bluetooth® 5.3 Low Energy and Proprietary 2.4 GHz applications. The device is optimized for low-power wireless communication with on-chip dual image Over the Air Download (OAD) support 1 in Building automation (wireless sensors, lighting control, beacons), asset tracking, medical, retail EPOS (electronic point of sale), ESL (electronic shelf label), and Personal electronics (toys, HID, stylus pens) markets. highlighted features of this device include:

  • Support for Bluetooth ® 5 features: High Speed Mode (2 Mbps PHY), Long Range (LE Coded 125 kbps and 500 kbps PHYs), Privacy 1.2.1 and Channel Selection Algorithm #2, as well as backwards compatibility and support for key features from the Bluetooth ® 4.2 and earlier Low Energy specifications.
  • Fully-qualified Bluetooth ® 5.3 software protocol stack included with the SimpleLink™ CC23xx Software Development Kit (SDK).
  • Zigbee® protocol stack support in the SimpleLink™ CC23xx Software Development Kit (SDK) (1)
  • Ultra-low standby current less than 0.71 µA with RTC operational and full RAM retention that enables significant battery life extension especially for applications with longer sleep intervals.
  • Integrated balun for reduced Bill-of-Material (BOM) board layout
  • Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth ® Low Energy (-102 dBm for 125 kbps LE Coded PHY, with integrated balun).

The CC2340R5 device is part of the SimpleLink™ MCU platform, which consists of Wi-Fi, Bluetooth Low Energy, Thread, Zigbee, Sub-1 GHz MCUs, and host MCUs that all share a common, easy-to-use development environment with a single core software development kit (SDK) and rich tool set. 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.
