SPI controller offers low pin-count alternative to SDIO, mini-PCI

Sunnyvale, Calif.—QuickLogic Corp. has added a serial peripheral interconnect (SPI) host controller to its customer-specific standard product (CSSP) functional library.

The SPI interface gives mobile device designers a low pin-count alternative to SDIO or mini-PCI for a high-speed connection to wireless modules and other popular peripheral functions.

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.
