CG200 SD/SDIO Host Controller
CG200EDK CG200 Reference Evaluation Board
|CG200 is an SD/SDIO Host controller device that supports High Speed SD
CG200 enables SD and SDIO Combo function easily; for example, IEEE802.11g and SD Memory card because CG200
supports dual SDIO host capabilities. CG200 registers are compliant with SD Host Controller Standard Specifiaction Version 1.0.
In addition, CG200 supports various interfaces such as IDE, PCI and Generic 8/16/32 bit loca bus linterface.
In IDE interface mode, CG200 transfers data with Ultra DMA mode 3 (Ultra ATA/44) and achieves SD Memory card throughput upto
20MB/s when using high speed SD Memory card.
CG200 IDE interface directly accesses SD Memory card, so that SD Memory card is used on PC system with IDE driver in OS.
