Texas Instruments CC3235MODx SimpleLink Wireless MCU Module

Texas Instruments CC3235MODx SimpleLink Dual-Band Wireless MCU Module is a fully programmable FCC, ISED/IC, ETSI/CE, and MIC Certified wireless microcontroller (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 has two 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, and secure boot and debug security. The CC3235MODSF builds on the CC3235MODS and integrates a user-dedicated 1MB of executable flash and 256KB of RAM.

Created for IoT, the Texas Instruments SimpleLink™ Wi-Fi® CC3235MODx module family is a wireless module that integrates two physically separated on-chip MCUs. It includes an application processor—Arm® Cortex®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of executable flash. It also has a 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 2.4GHz and 5GHz radio, baseband, and MAC with a powerful hardware cryptography engine.
