USB 3.0-SATA3 bridge SoC supports high-speed UASP protocol
Renesas also plans on achieving compatibility with AMD’s future USB3-supporting chipsets. The µPD720230 USB 3.0-SATA3 bridge SoC supports SuperSpeed USB transfer speeds of up to 5Gbit/s, as well as the SATA Revision 3.0 6Gbit/s bit rate, achieving maximum data transfer performance of USB 3.0. In addition to the BOT standard for mass storage devices using USB 2.0, the chip also supports the UASP protocol standardized in USB 3.0 for improving the performance limits of the BOT standard. When connected to an SSD that supports 6 Gbps SATA3, the µPD720230 device achieves data transfer performance in excess of 370 MB/s in UASP mode as verified by the ATTO Disk Benchmark, version 2.46.
The µPD720230 comes in a 48-pin QFN package. It incorporates a voltage regulator, and also supports bus power modes, which contribute to miniaturization of the end products. The new USB 3.0 SATA3 SoC reduces overall power consumption by approximately 40 percent (when the system is in the idle state) via the new USB 3.0 U1 and U2 power states, as compared to when stipulating only the U0 and U3 power states. A license of Renesas’ UASP driver is included with the company’s µPD720230 USB 3.0 to SATA3 Bridge and is available for license to other SATA bridge manufacturers.
