The CC2642R 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 additionto sub-μA sleep current with up to 80KB of parity protected RAM retention, provide excellent batterylifetime and allow operation on small coin-cell batteries and in energy-harvesting applications.

The CC2642R 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 RadioController (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 CC2642R devicedoes not come at the expense of RF performance; the CC2642R device has excellent sensitivity androbustness (selectivity and blocking) performance.

The CC2642R device is a highly integrated, true single-chip solution incorporating a complete RF systemand an on-chip DC/DC converter.

Sensors can be handled in a very low-power manner by a programmable, autonomous ultra-low powerSensor Controller CPU with 4KB of SRAM for program and data. The Sensor Controller, with its fastwake-up and ultra-low-power 2 MHz mode is designed for sampling, buffering, and processing bothanalog and digital sensor data; thus the MCU system can maximize sleep time and reduce active power.

The CC2642R device is part of the SimpleLink™ microcontroller (MCU) platform, which consists ofWi-Fi®, Bluetooth® Low Energy, Thread, Zigbee, Sub-1 GHz MCUs, and host MCUs, which all share acommon, easy-to-use development environment with a single core software development kit (SDK) andrich tool set. A one-time integration of the SimpleLink platform enables you to add any combination of theportfolio’s devices into your design, allowing 100 percent code reuse when your design requirementschange.
