• Enhanced Wi-Fi provisioning • Enhanced power consumption
• Enhanced file system security (supported only by the CC3220S and CC3220SF devices) Wi-Fi AP connection with up to four stations • More concurrently opened BSD sockets; up to 16 BSD sockets, of which 6 are secure
• HTTPS support
• RESTful API support
• Asymmetric keys crypto library
• The CC3220x wireless MCU family supports the following modes: station, AP, and Wi-Fi Direct®. The device also supports WPA2 personal and enterprise security. This subsystem includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols. The device supports a variety of Wi-Fi provisioning methods including HTTP based on AP mode, SmartConfig™ Technology, and WPS2.0.
• The power-management subsystem includes integrated DC-DC converters that support a wide range of supply voltages. This subsystem enables low-power consumption modes for extended battery life, such as low-power deep sleep, hibernate with RTC (consuming only 4.5 μA), and shutdown mode (consuming only 1 μA).
• The device includes a wide variety of peripherals, including a fast parallel camera interface, I2S, SD, UART, SPI, I2C, and 4-channel ADC.
