The ASM1456 is a high-speed USB 3.0 to SATA 6Gb/s bridge controller manufactured by Asmedia Technology Inc. It allows devices with a USB 3.0 interface to communicate with SATA storage devices (HDDs or SSDs) at high speeds.

Applications

• External hard drive enclosures
• USB 3.0 docking stations
• USB 3.0 to SATA adapters
• Portable storage devices

Features

• USB 3.0 compliant
• SATA 6Gb/s compliant
• Supports UASP (USB Attached SCSI Protocol) for increased transfer speeds
• Integrated 5V to 3.3V linear regulator
• Supports various SATA power saving modes
• Small form factor

Benefits

• High-speed data transfer between USB 3.0 and SATA devices
• Improved performance with UASP support
• Easy integration into various storage solutions
• Reduced power consumption
• Compact design

Additional Details

The ASM1456 bridges the gap between the high-speed USB 3.0 interface and the SATA 6Gb/s standard, enabling fast and efficient data transfer. UASP support allows for multiple commands to be processed simultaneously, further increasing transfer speeds compared to traditional BOT (Bulk-Only Transport) protocol. The integrated linear regulator simplifies power supply design. Consult the Asmedia datasheet for detailed electrical characteristics, pin assignments, and application notes.
