Texas Instruments CC2652R SimpleLink™ Multi-Band Wireless MCU

Texas Instruments CC2652R SimpleLink™ Multi-Band Wireless Microcontroller (MCU) is a multi-protocol 2.4GHz wireless MCU. This MCU targets Thread, Zigbee®, BLUETOOTH® 5 Low Energy, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), Wi-SUN® and proprietary systems, including the TI 15.4-Stack. The CC2652R device is a member of the SimpleLink™ MCU platform of cost-effective, ultra-low power, 2.4GHz, and Sub-1GHz RF devices. Very low active RF and microcontroller (MCU) current and 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 Texas Instruments CC2652R 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 stored in ROM or RAM, thus ensuring ultra-low power and great flexibility. The low power consumption of the CC2652R device does not come at the expense of RF performance; the CC2652R device has excellent sensitivity and robustness (selectivity and blocking) performance. The flexible radio of the CC2652R enables concurrent time-multiplexed multi-protocol operation through the Dynamic Multi-Protocol Manager (DMM) driver. The CC2652R device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter.
