The AN1312 module is designed based on CC1312R. The CC1312R device is a Sub-1GHz wireless MCU targeting Wireless M-Bus, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), KNX RF, Wi-SUN®, and proprietary systems, including theTI15.4-Stack.

The CC1312R device is a member of the SimpleLink™ MCU platform of cost-effective, ultra-low power,2.4-GHz and Sub-1 GHz RF devices. Very low active RF and microcontroller (MCU) currents, in addition to sub-μA sleep current with up to 80KB of parity protected RAM retention, provide excellent battery lifetime and allow operation on small coin-cell batteries and in energy-harvesting applications.

The CC1312R device combines a flexible, very low-power RF transceiver with a powerful 48-MHz Arm® Cortex®-M4F CPU in a platform supporting multiple physical layers and RF standards. A dedicated Radio Controller (Arm® Cortex®-M0) handles low-level RF protocol commands that are stored in ROM or RAM, thus ensuring ultra-low power and great flexibility. The low power consumption of the CC1312R device does not come at the expense of RF performance; the CC1312R device has excellent sensitivity and robustness (selectivity and blocking) performance.

The CC1312R device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter. Sensors can be handled in a very low-power manner by a programmable, autonomous

ultra-low power Sensor Controller CPU with 4KB of SRAM for program and data. The Sensor Controller, with its fast wake-up and ultra-low-power 2 MHz mode is designed for sampling, buffering, and processing both analog and digital.
