The leading IoT wireless module manufacturer, RF-star recently released two Sub 1GHz modules: RF-SM-1277B1 and RF-SM-1277B2. Both modules, featuring ultralow power consumption, were designed for middle or long-range applications. They are suitable for embedding applications in instrumentation, logistics, health and medication, building automation, sports measurement, automobile electronics, toys and surveillance in agriculture etc. Users can dramatically shorten development cycle for building new solutions and create edge for themselves in market development. RF-SM-1277B1 module supports 868 MHz and 915 MHz bands, and RF-SM-1277B2 module supports both bands of 433 MHz and 470 MHz.

Brief Introduction to CC1312R

Texas Instrument’s CC1312R is a wireless SoC designed for Sub1G ISM frequencies. It supports wireless M-Bus, IEEE 802.15.4g, 6LoWPAN, KNX RF, Wi-SUN® and proprietary systems including TI 15.4-Stack. The cost-effective chip boasting of extremely low power consumption features sleep mode current of less than 1µA. It also has a 80KB RAM assured by parity check and a Flash memory of 352KB, which are sufficient for building most applications in terminal nodes.

With a platform supporting multiple PHY and RF standards, CC1312R integrates a flexible ultralow power transceiver with a robust 48 MHz Arm® Cortex®-M4F CPU. A separate radio controller over Arm® Cortex®-M0 handles lower class RF protocol commands stored in ROM or RAM, thus keeping the whole system extremely energy effective and flexible. With a complete RF system and an on-chip DC/DC converter, CC1312R poised to be a highly integrated SoC solution.
