3 Description
The SimpleLink™ CC2651R3SIPA device is a multiprotocol 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 CC2651R3SIPA 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 CC2651R3SIPA is an ultra-compact 7-mm x 7-mm certified wireless module 2.4 GHz with integrated
antenna, DCDC components, Balun, and high frequency crystal oscillator.
The CC2651R3SIPA 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 CC2651R3SIPA supports +5 dBm TX at 9.6 mA in the 2.4-GHz band. CC2651R3SIPA has a receive
sensitivity of -104 dBm for 125-kbps Bluetooth® Low Energy Coded PHY.
The CC2651R3SIPA has a low sleep current of 0.9 μA with RTC and 32KB RAM retention.
TI has a product life cycle policy with a commitment to product longevity and continuity of supply.
The CC2651R3SIPA 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 MCU.CC2651R3SIPA
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
