Introduction

This device is a wireless MCU primarily designed for Bluetooth Low Energy. It belongs to the SimpleLink CC26xx family as a cost-effective, ultra-low-power 2.4GHz RF device. Its extremely low active RF and MCU current consumption, combined with low-power mode leakage current, ensure exceptional battery life, making it suitable for small coin cell battery-powered applications and energy harvesting applications.

The SimpleLink Bluetooth Low Energy CC2640 device incorporates a 32-bit ARM Cortex-M3 core running at 48MHz — the same frequency as the main processor — along with a rich peripheral feature set, including a unique ultra-low-power sensor controller. This sensor controller is well-suited for interfacing with external sensors and for autonomously collecting analog and digital data while the rest of the system remains in sleep mode. As a result, the CC2640 device is an ideal choice for applications where battery life, compact size, and ease of use are priorities.

The Bluetooth Low Energy controller is embedded in ROM and runs independently on an ARM Cortex-M0 processor. This architecture improves overall system performance and power efficiency while freeing up flash memory for application use.
