Start your design with the fully programmable FCC, IC/ISED, ETSI/CE, MIC, and SRRC certified wireless microcontroller (MCU) module with built-in dual-band Wi-Fi connectivity. The modules integrate the 40-MHz crystal, 32.768-kHz RTC clock, 32Mb SPI serial flash, RF filters, diplexer, and passive components.

The SimpleLink™ CC3235MODx module is available in two variants:

• CC3235MODS includes 256KB of RAM, IoT networking security, device identity and keys, and MCU-level security features such as file system encryption, user IP (MCU image) encryption, secure boot, and debug security.
• CC3235MODSF builds on the CC3235MODS and integrates a user-dedicated 1MB of executable flash in addition to the 256KB of RAM.

The SimpleLink™ CC3235MODAx module is available in two variants:

• CC3235MODAS includes 256KB of RAM, IoT networking security, device identity and keys, and MCU-level security features such as file system encryption, user IP (MCU image) encryption, secure boot, and debug security.
• CC3235MODASF builds on the CC3235MODAS and integrates a user-dedicated 1MB of executable flash in addition to the 256KB of RAM.

Created for IoT, the SimpleLink™ Wi-Fi^® CC3235MODxandCC3235MODAx module family from Texas Instruments is a wireless module that integrates two physically separated on-chip MCUs.
