3 Description
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) support3 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) 3
• 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. For more information, visit SimpleLink™ MCU
