3 Description

The SimpleLink™CC1311R3 device is a multiprotocol Sub-1GHz wireless microcontroller (MCU) supporting IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), mioty, proprietary systems, including the TI 15.4-Stack (Sub-1GHz). The CC1311R3 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 CC1311R3 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 143MHz to 176MHz, 287MHz to 351MHz, 359MHz to 527MHz, 861MHz to 1054MHz, and 1076MHz to 1315MHz frequency bands. The CC1311R3 has an efficient built-in PA that supports +14dBm TX at 24.9mA current consumption. In RX, it has -121dBm sensitivity and 88dB blocking ±10MHz in SimpleLink™ long-range mode with 2.5kbps data rate.

The CC1311R3 has a low sleep current of 0.7μA 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 CC1311R3 device is part of the SimpleLink™ MCU platform, which consists of Wi-Fi®, Bluetooth® Low Energy, Thread, Zigbee, Wi-SUN®, Amazon Sidewalk, mioty, Sub-1GHz MCUs, and host MCUs. CC1311R3 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 support 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.
