3 Description
The CC2340R SimpleLink™ family of devices are 2.4GHz wireless microcontrollers (MCUs), targeting
Bluetooth® 5.3 Low Energy, Zigbee, Thread, and Proprietary 2.4GHz applications. These devices are optimized
for low-power wireless communication with Over the Air Download (OAD) support in Building automation
(wireless sensors, lighting control, beacons), asset tracking, medical, retail EPOS (electronic point of sale),
ESL (electronic shelf), and Personal electronics (toys, HID, stylus pens) markets. Highlighted features of this
device include:
• Support for Bluetooth 5 features: high-speed mode (2Mbps PHY), long-range (LE Coded 125kbps and
500kbps PHYs), privacy 1.2.1 and channel selection algorithm #2, as well as backward 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™ Low Power F3 software
development kit (SDK)
• Zigbee® protocol stack support in the SimpleLink™ Low Power F3 software development kit (SDK)
• Thread protocol stack support in SIMPLELINK TI OPENTHREAD SDK (1)
• Ultra-low standby current less than 0.71μA 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
(–102dBm for 125kbps LE Coded PHY, with integrated balun)
The CC2340R family is part of the SimpleLink™ MCU platform, which consists of Wi-Fi®, Bluetooth Low
Energy, Thread, Zigbee, Sub-1GHz 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 the SimpleLink™
MCU platform.
