The SimpleLink™ Wi-Fi system-on-chip CC35xx family is where affordability meets reliability, enabling engineers to connect more applications with confidence. CC35xx are single-chip Wi-Fi 6 and Bluetooth Low Energy 5.4 wireless microcontrollers (MCUs). The CC3500E and CC3501E are the first dual-band devices in this pin-to-pin compatible family.

CC3500E: 2.4GHz Wi-Fi 6 wireless MCU
CC3501E: 2.4GHz Wi-Fi 6 and Bluetooth low energy 5.4 wireless MCU

The CC350xE offers the latest standards from Wi-Fi and BLE while maintaining compatibility with Wi-Fi 4 (802.11 b/g/n) and Wi-Fi 5 (802.11 ac). These CC350xE are the 10th-generation connectivity combo chip from Texas Instruments. As such, the CC350xE is based on proven technology. These devices are an excellent choice to use in cost-sensitive embedded applications with RTOS software. CC350xE 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.
