JMS581LT
- USB 3.2 Gen 2 to PCIe Gen3 x2 , SATA 6Gbps and SD7.1
- Support multi-LUN
- Support TRIM command for SATA and PCIe
Overview
JMS581LT is a single chip solution which embedded with USB 3.2 Gen 2, SATA 6Gbps, PCIe Gen3 x2 and SD7.1. The upstream port offers a USB port which data speed can reach up to 10Gbps. 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 backward compatible with legacy SD card. It can be considered as a perfect solution for all-in-one card reader or docking station solution.

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.
