OEMs are readying USB 3.0 PCIe add-on cards based on the reference design "USB3.0R-P2-PCIe", which will be sold through several vendors such as Buffalo. These cards take advantage of the new Renesas μPD720202 chipset, which is known to be more cost-effective, faster, and power-efficient than the μPD720200A, which it succeeds. The μPD720202 features a 40% performance boost over previous generation, the card has a redesigned circuit that reduces electrical leakage when in power-saving mode, when the chip consumes about 4.5 mW. The card gives out two USB 3.0 ports, and draws power from a 15-pin SATA power connector, instead of 4-pin Molex or Berg connectors. The PCB is compact, half-height, and hence low-profile capable. Cards should include low-profile brackets.
