JMS581

JMS581

  • USB 3.2 Gen 2 to PCIe Gen3 x2 , SATA 6Gb/s and SD7.1
  • Support multi-LUN
  • Support Offline File Copy and CLONE

Overview

JMS581 is a single chip solution for multimedia interfaces which embedded with USB3.2 Gen 2, SATA 6Gb/s, PCIe Gen3 x2 and SD7.1. The upstream provides a USB 10Gbps data transfer speed. The downstream port can connect to SATA, PCIe NVMe and SD Express storage devices, such as a hard drive, solid-state drive, CFast, CFexpress, SD7.1 and legacy SD card. JMS581 supports multi-LUN and a built-in Offline File Copy function that can further enhance user experience by backup files between these interfaces, no more PC/Laptop is required. By simplifying the process of data backup, users can save more time for creation.

JMS581D

JMS581D

  • USB 3.2 Gen 2 to PCIe Gen3 x2 and SATA 6Gb/s
  • Support simultaneous operation for PCIe and SATA
  • Support TRIM command for PCIe and SATA

Overview

JMS581D is a system on chip solution which embedded with USB 3.2 Gen2x1 10Gb/s, SATA 6Gb/s and PCIe NVMe Gen 3x2. Its upstream port provides a USB which data speed can reach up to 10Gb/s. Meanwhile, its downstream port can connect to SATA, PCIe NVMe storage devices, such as a hard drive, solid-state drive, CFast, CFexpress memory card. Furthermore, the special design inside the chip enables both interfaces of NVMe and SATA to operate independently and simultaneously.
