Overview

The CC1312R1F3RGZR is a Sub-1 GHz wireless microcontroller from Texas Instruments SimpleLink platform, combining a 48MHz Arm Cortex-M4F processor with a dedicated radio controller. It supports multiple physical layers and RF standards including 2-FSK, 4-FSK, and GFSK across a wide frequency range of 431MHz to 1329MHz. The device is engineered for long-range, ultra-low-power applications, featuring a dedicated sensor controller for autonomous data acquisition while the main CPU sleeps.

Why Choose This Part

The integrated Arm Cortex-M4F with 352kB Flash and 80kB RAM provides sufficient headroom for complex networking stacks and local edge processing. Its ultra-low power profile is industry-leading, consuming only 0.85uA in standby with full RAM retention and 0.15uA in shutdown. Integrated hardware security features like AES-128/256, ECC, and RSA acceleration ensure secure wireless data transmission without heavy software overhead.

Applications

Smart Grid and Metering
Ideal for wireless M-Bus and SUN (IEEE 802.15.4g) utility meters requiring long-range communication and multi-year battery life.
Building Automation
Connects HVAC sensors, lighting controllers, and security systems in large commercial structures where Sub-1 GHz signals provide superior wall penetration.
Industrial Monitoring
Enables robust wireless sensor networks in harsh RF environments with a high sensitivity of -125dBm for long-range links.
Electronic Shelf Labeling
Manages large-scale retail display updates using low-power wireless protocols with up to 4Mbps data rates.
