The dual-band wireless MCU CC3235x device comes in two variants, CC3235S and C3235SF.

  • The CC3235S includes 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 CC3235SF builds on the CC3235S and integrates a user-dedicated 1MB of executable flash in addition to the 256KB of RAM.

Simplify your IoT design with a Wi-Fi CERTIFIED™ wireless microcontroller (MCU). The SimpleLink™ Wi-Fi® CC3235x device family is a dual-band system-on-chip (SoC) solution that integrates two processors within a single chip, including:

  • Application processor: Arm® Cortex®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of executable flash
  • Network processor to run all Wi-Fi and internet logical layers. This ROM-based subsystem completely offloads the host MCU and includes an 802.11 a/b/g/n dual-band 2.4 GHz and 5 GHz radio, baseband, and MAC with a powerful hardware cryptography engine

These devices introduce new capabilities that further simplify the connectivity of things to the Internet. The main new features include:

  • 802.11a (5 GHz) support
  • BLE/2.4 GHz radio coexistence
  • Antenna selection
  • Enhanced security with FIPS 140-2 Level 1 certification and more (1)
  • Up to 16 concurrent secure sockets
  • Certificate sign request (CSR)
  • Online certificate status protocol (OCSP)
  • Wi-Fi® Alliance certified IoT power-saving features (such as DMS, proxy ARP, and so forth)
  • Hostless mode for offloading template packet transmissions
  • Improved fast scan

The CC3235x device family is part of the SimpleLink™ MCU platform—a common, easy-to-use development environment based on a single-core software development kit (SDK) with a rich tool set and reference designs. The E2E™ community supports Wi-Fi®, Bluetooth low energy, Sub-1 GHz, and host MCUs. For more information, visit www.ti.com/simplelink or www.ti.com/simplelinkwifi.
