JMS581SD

JMS581SD

  • USB 3.2 Gen 2 to SD7.1
  • Support PCIe Gen3 and NVMe 1.3 protocol
  • Support SDUC specification

Overview

JMS581SD is a system on chip solution which embedded with USB 3.2 Gen 2 to SD7.1 interfaces. Its upstream port provides a USB which data speed can reach up to 10Gbps. Meanwhile, its downstream port can connect to UHS-I and SD7.1 memory card, which can achieve up to maximum 985MB/s data transfer rate. It can also backward compatible with the legacy SD card specification. Furthermore, JMS581SD enable to meet with the latest SD Ultra Capacity (SDUC) card specification, which can offer the theoretical capacity up to 128TB.
