Texas Instruments' CC3120/CC3220 devices are part of the SimpleLink microcontroller (MCU) platform which consists of Wi-Fi, low energy, sub-1 GHz and host MCUs, which all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich tool set. A one-time integration of the SimpleLink platform enables the user to add any combination of the portfolio’s devices into their design, allowing 100 percent code reuse when the design requirements change.
| As part of TI’s SimpleLink Wi-Fi family second generation, the CC3120/CC3220 devices introduce the following features and enhanced capabilities: |
- IPv6
- 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, six of which are secure
- HTTPS support
- RESTful API support
- Asymmetric keys crypto library
|
