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.
