Texas Instruments CC3230S/CC3230SF SimpleLink™ Wi-Fi® Wireless MCUs

Texas Instruments CC3230S/CC3230SF SimpleLink™ Wi-Fi® Wireless Microcontrollers (MCUs) provide 256KB of RAM, IoT networking security, device identity/keys, as well as MCU level security features such as file system encryption, user IP (MCU image) encryption, secure boot and debug security. The CC3230SF variant also integrates a user-dedicated 1MB of executable Flash in addition to the 256KB of RAM. These devices simplify IoT (Internet of Things) designs with a Wi-Fi CERTIFIED™ wireless microcontroller. The Texas Instruments SimpleLink Wi-Fi CC330S/CC3230SF family is a system-on-chip (SoC) solution that integrates two processors within a single chip.
