(1) The CC3350 and CC3351 devices may operate at temperatures of up to 105°C. This allows the device to be used reliably in applications that may be exposed to higher ambient temperature over certain periods of the product’s life. At temperatures higher than 85°C, the WLAN/BLE performance may degrade. For more information please reference this application note https://www.ti.com/secureresources/CC33XX-THERMAL-GUIDELINES-NDA.
