1 Introduction

The JMS583 is a bridge controller between the USB host and the storage devices with PCIe/NVMe interface. Its

upstream port provides a USB which data speed can reach up to ten gigabits per second (10 Gb/s), or the data

transmission rate for USB 3.1 Gen 2 specification. Meanwhile, its downstream port can connect to PCIe/NVMe storage

devices, such as a solid-state drive (SSD). The data speed for the PCIe port can arrive at 16 Gb/s, or the data rate for

the PCIe Gen 3x2 requirements.

Also, the JMS583 has USB Type-C

TM connectivity built in to the controller that any device using the JMS583 can have

a USB Type-C

TM connector without adding any additional peripheral part. It can save costs to buy parts, and efforts to

build inventory, and it can reduce printed circuit board area for the system designs.

The JMS583 supports TRIM to the SSD and can transmit and receive data by both of USB Mass Storage Class

Bulk-Only Transport (BOT) and USB Attached SCSI Protocol (UASP) to and from the host respectively. The data

storage devices can achieve its summit of performance by taking advantage of these built-in unmatched features.

The JMS583 is well equipped for power management that it can meet a wide variety of power requirements from

different scales of data storage systems: those for data centers, network attached storage (NAS) systems, and

portable SSDs, and even those for thumb-sized Internet-of-Thing (IoT) devices.

Owing to its USB Type-C

TM connectivity, the JMS583 can work with some power management controllers to a USB

Power Delivery (PD) enabled data storage device. The data storage devices having SSDs of large capacity can accept

the electrical power from sources of energy, such as hosts acting as a power provider of USB PD to supply sufficient

electricity to the device after they negotiate with each other, without plugging in.

Finally, the JMS583 is a new product that almost reaches USB3.1 G2 line bandwidth. Using the JMS583, the security

system can transfer higher quality video, such as 4K or even 8K, and quicker to their data storage devices than ever.
