3 Description

The SimpleLink™ Wi-Fi CC33xx family of devices is where affordability meets reliability, enabling engineers

to connect more applications with confidence. CC33xx are single-chip Wi-Fi 6 and Bluetooth Low Energy 5.4

devices. The CC3350 and CC3351 are the first dual-band devices in this pin-to-pin compatible family.

• CC3350: A 2.4GHz and 5GHz Wi-Fi 6 companion IC

• CC3351: A 2.4GHz and 5GHz Wi-Fi 6 and Bluetooth low energy 5.4 companion IC

The CC335x offers Wi-Fi 6 and BLE while maintaining compatibility with Wi-Fi 4 (802.11 a/b/g/n) and Wi-Fi 5

(802.11ac). These CC335x are the 10th-generation connectivity combination chip from Texas Instruments. As

such, the CC335x is based on proven technology. These devices are ideal for use in cost-sensitive embedded

applications with a Linux or RTOS host running TCP/IP. CC335x brings the efficiency of Wi-Fi 6 to embedded

device applications for the internet of things (IoT), with a small PCB footprint and highly optimized bill of

materials.
