Texas Instruments CC3235MODx SimpleLink Dual-Band Wireless MCU Module is a fully programmable FCC, ISED/IC, ETSI/CE, and MIC Certified wireless MCU module with built-in dual-band Wi-Fi connectivity. The modules integrate the 40MHz crystal, 32.768kHz RTC clock, 32Mb SPI serial Flash, RF filters, diplexer, and passive components. The SimpleLink CC3235MODx module family comes in two different module variants (CC3235MOS and CC3235MODSF). The CC3235MODS includes 256KB of RAM, IoT networking security and device identity/keys. The device also has MCU level security features such as file system encryption, user IP (MCU image) encryption, secure boot and debug security. The CC3235MODSF builds on the CC3235MODS and integrates a user-dedicated 1MB of executable flash in addition to the 256KB of RAM.


Created for IoT, the module family is a wireless module that combines two physically separated on-chip MCUs. An application processor—Arm Cortex-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of executable flash. It also incorporates a network processor to run all Wi-Fi and Internet logical layers. This ROM-based subsystem fully offloads the host MCU and comprises an 802.11 a/b/g/n dual-band 2.4GHz and 5GHz radio, baseband, and MAC with a powerful hardware cryptography engine.


The module is ideal for IoT applications including medical and healthcare, building and home automation, asset tracking, factory automation, and grid infrastructure.
