CC2340R SimpleLink™ 2.4 GHz Wireless MCU with 512 KB Flash

Texas Instruments MCUs are designed for Bluetooth® 5.3 Low Energy, Zigbee®, Thread, and proprietary 2.4 GHz applications

Image of Texas Instruments CC2340R SimpleLink™ 2.4 GHz Wireless MCU with 512 KB flashThe Texas Instruments CC2340R SimpleLink family of devices are 2.4 GHz wireless microcontrollers (MCUs), targeting Bluetooth Low Energy (BLE), Zigbee, Thread, and proprietary 2.4 GHz applications. These devices are optimized for low-power wireless communication with over-the-air download (OAD) support in building automation (wireless sensors, lighting control, and beacons), asset tracking, medical, retail EPOS (electronic point of sale), ESL (electronic shelf), and personal electronics (toys, HID, and stylus pens) markets.

The CC2340R family is part of the SimpleLink MCU platform, which consists of Wi-Fi, BLE, 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 the addition of any combination of the portfolio’s devices into a design, allowing 100% code reuse when the design requirements change.
