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 fo
