The JMicron JMB352-LGGA0B is a single-chip, two-port eSATA II/USB 2.0 combo host controller. It's designed to provide both external SATA (eSATA) and USB 2.0 connectivity through a single chip, simplifying system design and reducing component count.

Applications

• Desktop PCs: Adding eSATA and USB 2.0 ports to desktop computers.
• Laptop Computers: Integrating eSATA and USB 2.0 functionality into laptops (though less common now).
• Motherboards: Providing eSATA and USB 2.0 support on motherboards.
• Add-in Cards: Creating eSATA and USB 2.0 add-in cards for PCs.
• Embedded Systems: Integrating eSATA and USB 2.0 connectivity into embedded devices.

Features

• eSATA II Support: Supports eSATA II data transfer rates (3.0 Gbps).
• USB 2.0 Support: Supports USB 2.0 data transfer rates (480 Mbps).
• Two Ports: Provides two eSATA/USB 2.0 combo ports.
• Single-Chip Solution: Integrates both eSATA and USB 2.0 functionality into a single chip.
• PCI Express Interface: Connects to the host system via PCI Express.

Benefits

• Simplified System Design: Reduces component count and simplifies system design.
• Cost-Effective: A more cost-effective solution compared to using separate eSATA and USB controllers.
• Increased Connectivity: Provides both eSATA and USB connectivity options.
• Improved Performance: Supports high-speed data transfer rates for both eSATA and USB.
• Easy Integration: Relatively easy to integrate into various systems.

Additional Details

The JMB352-LGGA0B utilizes the PCI Express interface for host connectivity. It supports hot-plugging for eSATA devices. Detailed technical specifications can be found in the JMicron datasheet. The eSATA ports are typically backward compatible with SATA I devices.
