Overview

The CC2640R2FRGZR is a member of the SimpleLink family from Texas Instruments, featuring a 48MHz Arm Cortex-M3 main processor and a dedicated Cortex-M0 for the RF core. It is a highly integrated Bluetooth 5.0 Low Energy (BLE) System-on-Chip (SoC) that includes a unique Ultra-Low Power Sensor Controller for autonomous data acquisition. This device is optimized for long battery life with a standby current of 1.1 uA and a shutdown current of 0.1 uA.

Why Choose This Part

The primary advantage is the dual-core architecture which offloads complex radio timing to a dedicated RF core, ensuring stable BLE performance while the main M3 handles application logic. It offers excellent RF sensitivity of -97dBm and an integrated DC-DC converter to maintain high efficiency across its 1.8V to 3.8V operating range.

Applications

Battery-Powered IoT Sensors
Utilizes the Ultra-Low Power Sensor Controller to monitor analog or digital sensors while the main Cortex-M3 core remains in standby.
Medical Wearables
The small 7x7mm VQFN package and integrated 12-bit ADC make it suitable for compact health monitoring devices.
Smart Home Locks
Provides secure BLE connectivity with an integrated AES-128 hardware encryption engine and True Random Number Generator (TRNG).

Getting Started

Developers should use the SimpleLink CC2640R2 Software Development Kit (SDK) and Code Composer Studio (CCS) or IAR Embedded Workbench. For rapid prototyping, the LAUNCHXL-CC2640R2 LaunchPad development kit provides a debugger and access to all I/O pins.

Also Consider

nRF52832 nRFNordic Semiconductor - Offers a more powerful Cortex-M4F core and larger RAM for more complex Bluetooth mesh applications.
CC2642R TITexas Instruments - An upgraded alternative with significantly more Flash (352kB) and RAM (80kB) for applications requiring OAD or larger software stacks.
