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.
