3 Description
The SimpleLink™ Wi-Fi CC33xx family of devices is where affordability meets reliability, enabling engineers to
connect more applications with confidence. CC335xMOD devices are certified modules designed to simplify
hardware design and reduce time-to-market.
• CC3350MOD: A 2.4GHz and 5GHz Wi-Fi 6 companion module
• CC3351MOD: A 2.4GHz and 5GHz Wi-Fi 6 and Bluetooth Low Energy 5.4 companion module
The CC335xMOD offers the latest standards from Wi-Fi and BLE while maintaining compatibility with Wi-Fi
4 (802.11 a/b/g/n) and Wi-Fi 5 (802.11ac). These CC335xMOD devices are based on the 10th-generation
connectivity combo chip from Texas Instruments. As such, the CC335xMOD is based on proven technology.
These modules are an excellent choice to use in cost-sensitive embedded applications with a Linux or RTOS
host running TCP/IP. CC335xMOD brings the efficiency of Wi-Fi 6 to embedded device applications for the
Internet of Things (IoT).
