Overview

The CC3235SF12RGKR is a dual-band Wi-Fi SoC from Texas Instruments that integrates an Arm Cortex-M4 application processor running at 80MHz with a dedicated network processor. It supports 802.11a/b/g/n across both 2.4GHz and 5GHz frequencies and features 1MB of executable Flash and 256kB of RAM. This device is designed for secure IoT applications, offering FIPS 140-2 Level 1 certification and extensive hardware-based security features.

Why Choose This Part

The dual-core architecture offloads the entire Wi-Fi stack and security processing to a dedicated network processor, freeing the Cortex-M4 for application code. It offers superior reliability in crowded RF environments by supporting the 5GHz band and provides a robust hardware security suite including secure boot, storage, and debugging.

Applications

Secure Industrial Gateway
Leverages FIPS 140-2 security and dual-band Wi-Fi to provide a reliable and encrypted bridge between industrial sensors and cloud platforms.
Smart Home Security
Ideal for battery-powered cameras and door locks requiring 5GHz Wi-Fi to avoid 2.4GHz congestion while maintaining low power consumption.
Asset Tracking
Utilizes low-power deep sleep modes and integrated power management for long-term battery operation in portable tracking devices.
Medical IoT
Provides secure, authenticated data transmission for patient monitoring systems in hospital environments using the 5GHz band.
