Texas Instruments CC3235MODx SimpleLink dual-band wireless MCU modules

The CC3235MODx SimpleLink dual-band wireless microcontroller modules, from Texas Instruments (TI), integrate a high-performance application processor, network processor and crypto engine in a single chip with a rich set of peripherals. The CC, ISED/IC, ETSI/CE and MIC-certified CC3235MODx modules are suitable for a wide range of Internet of Things (IoT), building automation, security and healthcare applications.

The modules integrate a 40 MHz crystal, 32.768 kHz RTC clock, SPI serial flash, RF filters, diplexer and passive components, plus a network processor that runs all Wi-Fi and internet logical layers. The network processor subsystem completely offloads the host microcontroller and includes an 802.11a/b/g/n dual-band 2.4 and 5 GHz radio, baseband and MAC with a powerful hardware cryptography engine.

The devices feature capabilities that are intended to simplify the connectivity of IoT applications, including 802.11a/n 5 GHz support, coexistence capabilities for radios in the 2.4 GHz band (such as Bluetooth Low Energy), antenna selection, enhanced security with FIPS 140-2 Level 1 certification, up to 16 concurrent secure TCP/IP sockets and a certificate sign request (CSR).

The modules are available in two variants: the CC3235MODS and CC3235MODSF. The CC3235MODS incorporates an Arm Cortex-M4 microcontroller with 256 KB of application RAM, IoT networking security and device identity/keys. The CC3235MODSF builds on the CC3235MODS and adds a user-dedicated 1 MB of executable flash in addition to the 256 KB of RAM. Both variants offer microcontroller-level security features such as file system encryption, user IP (microcontroller image) encryption, secure boot and debug security.
