Description for the CC2651R3

The SimpleLink™ CC2651R3 device is a single-protocol 2.4-GHz wireless microcontroller (MCU) supporting Zigbee , Bluetooth 5.2 Low Energy, IEEE 802.15.4g, TI 15.4-Stack (2.4 GHz). The CC2651R3 is based on an Arm® Cortex® M4 main processor and optimized for low-power wireless communication and advanced sensing in grid infrastructure, building automation, retail automation, personal electronics and medical applications.

The CC2651R3 has a software defined radio powered by an Arm® Cortex® M0, which allows support for multiple physical layers and RF standards. The device supports operation in the 2360 to 2500-MHz frequency band. The CC2651R3 supports +5 dBm TX at 9.5 mA in the 2.4-GHz band. CC2651R3 has a receive sensitivity of -104 dBm for 125-kbps Bluetooth® Low Energy Coded PHY.

The CC2651R3 has a low sleep current of 0.8 µA with RTC and 32KB RAM retention.

Consistent with many customers’ 10 to 15 years or longer life cycle requirements, TI has a product life cycle policy with a commitment to product longevity and continuity of supply.

The CC2651R3 device is part of the SimpleLink™ MCU platform, which consists of Wi-Fi®, Bluetooth® Low Energy, Thread, Zigbee, Wi-SUN®, Amazon Sidewalk, mioty, Sub-1 GHz MCUs, and host MCUs. CC2651R3 is part of a scalable portfolio with flash sizes from 32KB to 704KB with pin-to-pin compatible package options. The common SimpleLink™CC13xx and CC26xx Software Development Kit (SDK) and SysConfig system configuration tool supports migration between devices in the portfolio. A comprehensive number of software stacks, application examples and SimpleLink™ Academy training sessions are included in the SDK. For more information, visit wireless connectivity.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
