Texas Instruments has launched a dual-band wireless microcontroller (MCU) that supports sub-1 GHz and Bluetooth low energy connections on a single chip for under $5.
The SimpleLink dual-band CC1350 wireless MCU enables developers to move from a three-chip solution to one, reducing design complexity and saving power, cost and board space. The sub-GHx capability gives the CC1350 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, while the Bluetooth connection gives an easy link to a node via a smartphone or tablet.
The device is based around an ARM Cortex-M3 core in a single, Flash-based, 4x4 mm QFN package with a sleep current of 0.7 uA that allows for more than 10 years of battery life.
Developers can get started quickly with the low-cost CC1350 wireless MCU LaunchPad development kit or connect sensors to the cloud in minutes with the CC1350 SensorTag demo kit supported by TI’s Code Composer Studio integrated development environment (IDE) and IAR's Embedded WorkBench. TI has also simplified development by providing multiple software options including 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 (SDK) which supports Bluetooth 4.2 specifications. This small, sensor-based kit includes 10 low-power MEMS sensors and can connect to the cloud in less than three minutes.
The LaunchPad kit (LAUNCHXL-CC1350) costs $29.00, the SensorTag demo kit (CC1350STK) coming in 4Q 2016 for $29.99.
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 4x4, 5x5 and 7x7 mm QFN packages.
The devices available now are for 868 MHz, 915 MHz and 920 MHz ISM band operation and the 7x7 mm pricing is $4.60 in 1,000 unit volumes
