As part of TI’s pin-to-pin and software compatible SimpleLink ultra-low power platform, the SimpleLink dual-band CC1350 wireless MCU enables developers to move from a three-chip solution to a single chip, while reducing design complexity, saving power, cost and board space. The CC1350 wireless MCU offers a range of up to 20 km on a coin cell battery for building and factory automation, alarm and security, smart grid, asset tracking and wireless sensor network applications.

Designed for low-power wide area networks (LPWAN), the CC1350 wireless MCU features dual-band connectivity; a sub-1 GHz network together with Bluetooth low energy allows implementations such as beaconing, over-the-air updates, smart commissioning, remote displays and more. Long-range connectivity paired with ultra-low power consumption comes with a sleep current of 0.7 µA which allows for more than 10 years of battery life. The wireless MCU combines a Sub-1 GHz transceiver and Bluetooth low energy radio, as well as an ARM Cortex-M3 core in a single, Flash-based, 4×4 mm QFN package.

Development tools include the low-cost SimpleLink CC1350 wireless MCU LaunchPad development kit; connection to the cloud is demonstrated by the SimpleLink CC1350 SensorTag demo kit supported by TI’s Code Composer Studio integrated development environment (IDE) and IAR Embedded WorkBench. TI has multiple software options including point-to-point communication examples with EasyLink, a wireless M-Bus protocol stack using TI RTOS, as well as the BLE-Stack 2.2 software development kit (SDK) which supports Bluetooth 4.2 specifications.

SimpleLink Sub-1 GHz CC1350 wireless MCU-based development kits comprise:

The CC1350 LaunchPad kit (LAUNCHXL-CC1350) for $29.00 supporting development of a complete prototype with a low-cost Sub-1 GHz and Bluetooth low energy wireless MCU hardware, software and RF development platform.

The CC1350 SensorTag demo kit (CC1350STK), coming in 4Q 2016, for $29.99 – hosts a Sub-1 GHz and Bluetooth low energy project with a small, sensor-based kit which includes 10 low-power MEMS sensors and can connect to the cloud in less than three minutes.

The SimpleLink Sub-1 GHz CC1350 wireless MCUs, for operation in 315 MHz, 433 MHz, 470 MHz, 500 MHz, 779 MHz, 868 MHz, 915 MHz and 920 MHz and 2.4 GHz ISM bands and SRD systems, will be available in 4×4, 5×5 and 7×7 mm QFN packages. The devices available today are for 868 MHz, 915 MHz and 920 MHz ISM band operation and the 7×7 mm pricing for the CC1350F128RGZ is $4.60 (1,000).
