Wireless MCUs provides very low active RF and MCU current

Texas Instruments CC1312R SimpleLink Wireless MCUs are aimed at Wireless M-Bus, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), KNX RF, Wi-SUN, and proprietary systems, and includes the TI 15.4-Stack. The device provides very low active RF and MCU current. It also has sub-µA sleep current with up to 80KB of parity protected RAM retention. This provides outstanding battery life and enables operation on small coin-cell batteries and in energy-harvesting applications. The device combines a flexible, very low-power RF transceiver with a powerful 48MHz 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 device does not come at the expense of RF performance; the device provides excellent sensitivity and robustness (selectivity and blocking) performance.
