The extremely low power Simple Link wireless platform from TI is suitable for Bluetooth Smart, 6LoWPAN, ZigBee, Sub-1 GHz ZigBee RF4CE and.
Customers would be able to do without either by energy harvesting entirely on batteries or comment in the always-on operation for several years with a single button cell. “This technique is a first in the industry and gives customers flexible development opportunities for products that support a single chip and identical RF design more radio access standards,” said Oyvind Birkenes, General Manager, Wireless Connectivity Solutions at TI.

The Simple Link Ultra-low-power platform supports Bluetooth Low Energy, ZigBee, 6LoWPAN, Sub-1 GHz ZigBee RF4CE and proprietary implementations as well as with data rates up to 5 Mbit / s. With an ARM Cortex-M3-based MCU, Flash / RAM, A / D converter, peripheral, a sensor controller, and robust security it offers a high degree of integration.

The simple design of this platform is the result of immediately deployable protocol stacks, operating system, TI RTOS, the integrated development environment (IDE) Code Composer Studio, the tools, online training and support from the E2E Community, so Birkenes. The available reference designs facilitate the development and layout, so that a minimum amount of HF sufficient expertise. About the TI IoT Cloud Ecosystem TI also facilitates its customers to the cloud connection.
The first products of the Simple Link Ultra-Low-Power Wireless MCU platform of CC2640 Bluetooth Smart and CC2630 for 6LoWPAN and ZigBee. For more flexibility, the wireless MCU CC2650 can be used, which supports multiple 2.4-GHz technologies, including Bluetooth Smart, 6LoWPAN, ZigBee RF4CE and. Additional products will follow later this year, the CC1310 sub-1 GHz for the operation and the CC2620 ZigBee RF4CE.
Trimmed for low power
The ultra-low-power platform is designed for low power consumption. A dedicated onboard sensor controller speaks the external sensors to autonomously, while the rest of the block is in Sleep mode. Characteristic of the platform are less than 6.2 mA draw maximum current consumption with active radio operation and under 61 uA / MHz lying power consumption of the MCU in the active state.
The entire chip can be placed in a standby status, with only 1.1 uA current consumption for retention of memory and running real-time clock (RTC). Birkenes: “The platform comes with it to half the power of other MCUs, such as the value of 143.6 of the EEMBC benchmarks shows ULPBench A blog post includes information about how the battery-free operation can be realized..”
