Texas Instruments CC335x SimpleLink™ Dual-Band Wi-Fi® 6 Companion IC

Texas Instruments CC335x SimpleLink™ Dual-Band Wi-Fi® Companion ICs offer 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 cost-sensitive embedded applications with a Linux or RTOS host running TCP/IP. Texas Instruments CC335x brings the efficiency of Wi-Fi 6 to embedded device applications for the Internet of Things (IoT) with a small PCB footprint and a highly optimized bill of materials. The CC3350 is a 2.4GHz and 5GHz Wi-Fi 6 companion IC, whereas the CC3351 is a 2.4GHz and 5GHz Wi-Fi 6 and BLUETOOTH® Low Energy 5.4 companion IC.
