Wireless microcontroller monitors IoT and supports Bluetooth low energy

Claimed to be the lowest-power, dual-band wireless microcontroller supporting sub-1GHz and Bluetooth low energy connectivity on a single chip, the CC1350 has been launched by Texas Instruments.

The SimpleLink microcontroller reduces the conventional three-chip solution to a single chip, says the company, reducing design complexity, saving power, cost and board space. The wireless microcontroller combines a sub-1GHz transceiver, Bluetooth low energy radio and an ARM Cortex-M3 core in a single, Flash-based 4.0 x 4.0mm QFN package.

It is designed for low power, wide area networks (LPWAN) and offers a range of up to 20km on a coin cell battery for building and factory automation, alarm and security, smart grid, asset tracking and wireless sensor network applications.

The dual-band connectivity means that it can be used in sub-1GHz network with Bluetooth low energy implementations such as beaconing, over-the-air updates, smart commissioning and remote displays. The long range connectivity, paired with low power consumption offers a sleep current of 0.7microA which allows for more than 10 years of battery life.

According to the company, developers can get started in minutes with the low-cost SimpleLink CC1350 wireless MCU LaunchPad development kit or connect sensors to the cloud in minutes with the SimpleLink CC1350 SensorTag demo kit supported by the company’s Code Composer Studio IDE and IAR Embedded WorkBench.

Software options include point-to-point communication examples with EasyLink, a wireless M-Bus protocol stack leveraging TI RTOS, as well as the BLE-Stack 2.2 software development kit which supports Bluetooth 4.2 specifications.
