Renesas Electronics second-generation USB 3.0-SATA3 Bridge SoC

The SuperSpeed Universal Serial Bus (USB 3.0) to Serial ATA (SATA) Revision 3 [Note] bridge SoC (system on chip, part number μPD720231) enables the reduction of the total BOM significantly. The uPD720231 enables effective multigigabit per second (Gbps) data transfer between a USB 3.0 host system and a SATA device used in widely adopted external USB hard drives and solid state drives (SSD).

As the demand for media storage capacities and data transfer speed increases, the uPD720231 offers a fundamental building block to create an improved user experience for external USB storage.

The μPD720231 device was developed to respond to the need to reduce the number of components and to simplify printed circuit board (PCB) controller design.

Key features of the μPD720231 SoC: contributes to downsizing and power saving; support for SATA Revision 3.0 enables 6 Gbps high-speed data transfer; supports high-speed UASP protocol, independent of OS; seamless connectivity with proven Physical Layer (PHY) core; supports optical disc drive by ATAPI command support.
