The document introduces a USB 3.0 serial ATA bridge IC MB86C30A developed by FUJITSU, which is optimal for external memory devices such as hard disk drives (HDDs) complying with the USB 3.0 standard SuperSpeed with 5Gbps transfer speed.
The MB86C30A bridges USB 3.0 SuperSpeed (5 Gbps) and Serial ATA (3 Gbps) for external storage devices such as hard‑disk drives, SSDs, Blu‑ray and DVD. It offers up to ten‑times faster transfer rates than USB 2.0, reducing large file copy times.
The device integrates the USB and SATA interface, control logic, and a high‑speed AES encryption engine on a single LQFP64 package, enabling compact USB 3.0 storage products with optional firmware customization and encryption features.
