Texas Instruments CC2642R SimpleLink Bluetooth Low Energy MCU is a wireless MCU that targets Bluetooth 4 and 5 Low Energy applications. The device is a member of the SimpleLink MCU platform of cost-effective, ultra-low power, 2.4GHz and Sub-1GHz RF devices. The device has very low active RF and MCU current, in addition to sub-µA sleep current with up to 80KB of parity protected RAM retention. This device also offers exceptional battery life and provides for operation on small coin-cell batteries and in energy-harvesting applications.
The device unites 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) manages low-level RF protocol commands that are saved in ROM or RAM, thus securing ultra-low power and great flexibility. The low power consumption of the device does not come at the expense of RF performance; the device has superior sensitivity and robustness (selectivity and blocking) performance. The device is a highly integrated, true single-chip solution including a complete RF system and an on-chip DC-DC converter.
