Wi-Fi® CC3235MOD Dual-Band Wireless Microcontroller Module with built-in Dual-
Band (2.4 GHz and 5 GHz) Wi-Fi
®
connectivity. Created for the Internet-of-Things (IoT), the SimpleLink™
CC3235MODx family of devices from Texas Instruments™ are wireless modules that integrate 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 Serial Flash.
• A network processor MCU to run all Wi-Fi and Internet logic layers. This ROM based subsystem
includes an 802.11 a/b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure
internet connections with 256-bit encryption.
The CC3235MODx comes in 2 variants:
• CC3235MODSM2MOB
– Requires an external antenna
• CC3235MODSF12MOB
– Requires an external antenna
– Contains 1MB of Serial Flash
The LAUNCHCC3235MOD is a low-cost evaluation platform for MCUs based on Arm

-M4
devices. The LaunchPad™ design highlights the CC3235MODSF fully-integrated industrial module
solution and Dual-Band Wi-Fi capabilities. The LAUNCHCC3235MOD also features temperature and
accelerometer sensors, programmable user buttons, an RBG LED for custom applications, and onboard
emulation for debugging. The stackable headers interface demonstrates how easy it is to expand the
functionality of the LaunchPad when interfacing with other peripherals on existing BoosterPack™ add-on
boards, such as graphical displays, audio codec, antenna selection, environmental sensing, and more.
