Architecture Overview
1.1 Introduction
The CC3235x device is part of the SimpleLink™ microcontroller (MCU) platform which consists of Wi-Fi
®
,
Bluetooth
®
low energy, Sub-1 GHz and host MCUs, which all share a common, easy-to-use development
environment with a single core software development kit (SDK) and rich tool set. A one-time integration of
the SimpleLink™ platform lets you add any combination of the devices from the portfolio into your design.
The ultimate goal of the SimpleLink™ platform is to achieve 100 percent code reuse when your design
requirements change. For more information, visit www.ti.com/simplelink.
The applications MCU subsystem contains an industry-standard Arm
®
Cortex
®
-M4 processor core running
at 80 MHz. The device includes a wide variety of peripherals, including a fast parallel camera interface,
I2S, SD, UART, SPI, I2C, and 4-channel ADC. The CC32xx family of devices includes flexible embedded
RAM for code and data, and ROM with external serial flash bootloader and peripheral drivers.
The Wi-Fi
®
network processor subsystem features a Wi-Fi
®
Internet-on-a chip™, and contains an
additional dedicated Arm MCU that completely offloads the applications MCU. This 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 CC32xx device supports Station, Access Point, and Wi-Fi Direct
®
modes. The device also supports WPA2 personal and enterprise security and WPS 2.0. The Wi-Fi
®
Internet-on-a chip™ includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet
protocols.
