2 Main Features

Table 2-1 lists the main features supported by the CC33xx companion IC.

Table 2-1 CC33xx Main Features
Feature Description
Wi-Fi host interface SDIO or SPI.
For more information see Section 2.1.
BLE host interface
  • UART
  • SDIO or SPI on a shared interface

For more information, see Section 2.1.
Shared host interface for Wi-Fi and Bluetooth Low Energy Over SDIO or SPI to save hardware pins.
For more information, see Section 2.2.
Automatic host interface detection Yes
Autonomous mode Going to sleep and wakeup without informing the host. Implemented over UART, SPI and SDIO.
For more information, see Section 2.3.
Secured host interface Expected in later phase
Out-of-band interrupt
  • Separate – one for Wi-Fi and one for Bluetooth Low Energy
  • Shared – single one for both Wi-Fi and Bluetooth Low Energy

For more information, see Section 2.4.
In-band interrupt In SDIO mode.
For more information, see Section 2.4.
