1. Chip Information
The JMicron JMB321 is a single chip, 1 to 5-port Serial ATA II Port Multiplier. It is designed to provide SATA port expansion at various applications.
JMB321 us JMicron’s production-proven Multi-port Serial ATA PHY technology. With an easy scheme, the device can be a pure port multiplier which provides SATA port expansion just like USB Hub.
JMB321 is a lf-contained storage processor chip which completely frees up the main CPU loading and the SATA ports comply with eSATA specification, making it suitable for u in both internal system and external storage applications.
