Overview
JMS578
USB 3.1 Gen1 to SATA 6Gb/s
Bridge Controller
The JMS578 is a USB 3.1 Gen1 to SATA 6Gb/s bridge controller. It provides a low power and highperformance solution for external solid state drive (SSD), hard disk drive (HDD), and optical disc drive
(ODD).
The JMS578 supports higher data transmission rate and lower power consumption than its predecessors
ever, meanwhile, a two-layer printed circuit board (PCB) design for a cost-sensitive data storage
solution.
Moreover, the JMS578 can combine with JMicron’s SATA port multipliers to construct a data storage
device with multiple bays of HDDs to meet the requirement for large capacity data storage applications.
