3 Description

The SimpleLink? CC2340R2 device is a 2.4 GHz wireless microcontroller (MCU) targeting Bluetooth? 5 Low

Energy and Zigbee?. The device is optimized for low-power wireless communication as an entry-level SoC

(system-on-chip) to enable a broad range of end products in categories such as medical, building automation,

beacons, asset tracking, disposables, smart grid and personal electronics. Additionally, the CC2340R2 device

can function as an attached Bluetooth Low Energy network processor (or “data pump”) adding full Bluetooth Low

Energy capability to the main MCU via a serial interface. 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? Green Power 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).

? Pin to Pin compatible with CC2340R5 RGE Package.

The CC2340R2 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
