Sanechips (ZTE subsidiary) NB-IoT RoseFinch7100 ARM Cortex-M0

Posted by Charbax – September 16, 2018

RoseFinch7100 has passed the certification of China Mobile and China Telecom, and it has been widely deployed in gas meters, household appliances, municipal management (parking, manhole cover, street lamp, environmental monitoring) and other industries.

The demonstration will show the RoseFinch7100 running the Zephyr RTOS with integrated IP/TCP/UDP/COAP/MQTT/LWM2M protocols, IoT Cloud Engine and FOTA services. Sanechips has worked closely with the Linaro IoT and Embedded (LITE) group to enable upstream Zephyr support for the chip. The Sanechips Development Environment (SDE), based on OpenOCD (Open On-Chip Debugger) and Eclipse, will also be demonstrated.

Produced on a 55nm ultra low power technology process, the RoseFinch7100 is specifically designed for intensive low power IoT applications, such as cellular LPWA (low power wide area). The chip integrates the low power/high performance CEVA-X1 DSP IP for baseband and offers low sleep current of 2uA at 2V, which can provide an extended battery life. It also offers Cloud-Chip Global Security based on Trusted Zone, up to 30 GPIOs and all R14 Frequency Bands, and no need for an external MCU as the RoseFinch7100 can provide strong connectivity for most LPWA applications independently.
