CC3235MODAS SimpleLink™ Wi-Fi CERTIFIED™ Dual-Band Wireless Antenna Module Solution

Texas Instruments' CC3235MODAS fully-programmable FCC, IC/ISED, ETSI/CE, MIC, and SRRC certified wireless microcontroller (MCU) module with built-in dual-band Wi-Fi connectivity is a great way to start designing. The modules integrate a 40 MHz crystal, 32.768 kHz RTC clock, 32 MB SPI serial Flash, RF filters, a diplexer, and passive components. These devices include 256 KB of RAM, IoT networking security, device identity and keys, and MCU-level security features such as file system encryption, user IP encryption, secure boot, and debug security. The CC3235MODASF builds on the CC3235MODAS integrating a user-dedicated 1 MB of executable Flash in addition to the 256 KB of RAM.

Created for IoT, the SimpleLink Wi-Fi CC3235MODAS wireless module integrates two physically separated on-chip MCUs and utilizes an Arm Cortex-M4 application processor with a user-dedicated 256 KB of RAM and an optional 1 MB of executable Flash. A network processor runs the Wi-Fi and internet logical layers. This ROM-based subsystem 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.

The CC3235MODAS device is part of the SimpleLink MCU platform which is 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™ support forums support Wi-Fi, Bluetooth® low energy, Sub-1 GHz, and host MCUs. This generation introduces capabilities that simplify the connectivity of things to the Internet.
