New sub-1GHz MCU IoT solution spans 20km on a coin cell

Texas Instruments (TI) has announced the availability of the next device in the SimpleLink ultra low-power platform, designed to help users easily add ultra low-power, long-range connectivity to their Internet of Things (IoT) designs. The new SimpleLink Sub-1GHz CC1310 wireless microcontrollers (MCUs) offers up to 20 years of battery life for building and factory automation, alarm and security, smart grid and wireless sensor network applications. Features include : 1 - Extended battery life with an ultra-low power radio, integrated ARM Cortex-M3 MCU, sensor controller, low-power modes and 0.6µA sleep current, as well as a top ULPBench score of 158 2 - Longer range with great sensitivity and strong coexistence that spans full-buildings to city-wide coverage for over 20 km on a coin cell battery 3 - Enhanced integration in a fingertip size wireless MCU that provides a small footprint with more possibilities in a single-chip, Flash-based, 4X4 QFN for your coin-cell application TI has simplified development with the SimpleLink CC1310 wireless MCUs by providing software options to fit a developer’s needs. The software available today includes point-to-point communication examples with EasyLink and a wM-Bus protocol stack leveraging TI RTOS, as well as a Contiki 6LoWPAN mesh networking stack. Developers will also have access to development tools, reference designs, online training and E2E community support to help ease their design process. Additionally, TI offers scalable memory to fit developer’s code size with 32kB, 64kB, or 128kB Flash. For operation in 315MHz, 433MHz, 470MHz, 500MHz, 868MHz, 915MHz and 920MHz ISM bands, the SimpleLink Sub-1GHz CC1310 wireless MCUs will be available in 4mm x 4mm, 5mm x 5mm and 7mm x 7mm QFN packages. The devices available now are for 868MHz, 915MHz and 920MHz ISM bands, says the company.
