Wireless chipsets provide different host interfaces, including SDIO, SPI and mini-PCI. Implemented in QuickLogic's platform products, a SDIO host controller requires 15 customizable building blocks (CBBs), and PCI requires six to nine CBBs, depending on the configuration. The SPI host controller requires three CBBs and four IOs, freeing CSSP resources for implementing additional functions. It is capable of operating at clock speeds to 52 MHz.
The SPI host controller, which comes with full software support, is available immediately.
