3 Description
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 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 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.
