CC3235MODASF SimpleLink™ Wi-Fi CERTIFIED™ dual-band wireless antenna module solution

Description

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

The SimpleLink™ CC3235MODAx module family come in two different module variants:

CC3235MODAS includes 256KB of RAM, IoT networking security, device identity/keys, as well as, 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^® CC3235MODAx module family from Texas Instruments™ is a wireless module that integrates two physically separated on-chip MCUs.

Application processor—Arm^® Cortex^®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of executable flash.
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 2.4 GHz and 5 GHz radio, baseband, and MAC with a powerful hardware cryptography engine.

This generation introduces new capabilities that further simplify the connectivity of things to the Internet. The main new features include:

802.11 a/b/g/n: 2.4 GHz and 5 GHz support
2.4 GHz Coexistence with Bluetooth^® low energy radio
Antenna diversity
Enhanced security with FIPS 140-2 Level 1 validated IC inside: certification.
More concurrent secure sockets (up to 16)
Certificate signing request (CSR)
Online certificate status protocol (OCSP)
Wi-Fi Alliance^® certified for IoT applications with low-power capabilities and more
Hostless mode for offloading template packet transmissions
Improved fast scan

The CC3235MODAx device family is part of the SimpleLink™ MCU platform—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™ community supports Wi-Fi^®, Bluetooth^® low energy, Sub-1 GHz, and host MCUs. For more information, visit www.ti.com/simplelink or www.ti.com/simplelinkwifi.
