TI CC2640R2FRSMR

The CC2640R2F device is a wireless MCU primarily designed for Bluetooth 4.2 and Bluetooth 5 low energy applications. This device belongs to the SimpleLink CC26xx family of cost-effective, ultra-low-power 2.4GHz RF devices. Its extremely low active RF and MCU current consumption, combined with low-power mode current draw, ensures outstanding battery life, making it suitable for small coin cell battery-powered applications and energy harvesting applications. The SimpleLink Bluetooth Low Energy CC2640R2F device integrates 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 ideal for interfacing with external sensors and for autonomously collecting analog and digital data while the rest of the system is in sleep mode. As a result, the CC2640R2F device is an ideal choice for applications that prioritize battery life, compact size, and ease of use. The Bluetooth Low Energy controller and host library are embedded in ROM and run independently on an ARM Cortex-M0 processor. This architecture improves overall system performance and power efficiency, while freeing up significant flash memory for application use.
