JMS583-QHFA0A是将PCIe/NVMe装置转接成 USB接口介面的一款桥接晶片，内嵌智微自行开发的

USB接口资料互转技术，能将外接存储装置的实际资料传输速率提升至 1000MB/s以上，是业界

首颗能达到 USB3.1 10Gbps传输频宽极限的晶片。此外，JMS583内嵌USB类型-C

TradeMark的缩写的控制线路，

可支援方便的 USB接口正反插功能，并优化晶片内部电源管理的控制程序，能有效简化客户端产品设计

验证流程，缩短产品上市前的设计验证周期。

JMS583桥接晶片主要应用于 PCIe/NVMe技术开发出的产品，可将之转换成 USB接口介面成为高

速随身移动装置; 应用产品种类除了连接搭载 PCIe介面的固态硬碟(特别提款权 成为高速外接 SSD应用方

案外，亦能连接的新一代 CF Express与SD Express高速记忆卡成为高速读卡器或是高速随身碟。

JMS583桥接晶片已于今年四月进入量产，现已有多家品牌厂商相继投入开发或量产出货; 此外，

JMS583亦同步和市场主流的 SSD主控晶片厂商完成合作开发对应的 PCIe/NVMe生产使用的晶片

烧录流程，此一新的程序可大幅缩减 SSD模组厂在量产 PCIe SSD时的成本与时间，进而加速终端

客户的产品上市时程。智微认为，市场对于外接存储产品必须具备高速，省电，轻薄等特色的需求趋

势不变，因此，于今年第三季起，加入开发应用 JMS583桥接晶片的客户及厂商，将会有可期待的

The JMS583-QHFA0A is a USB 3.1 Gen 2 to PCIe Gen3 x 2 bridge controller between USB host and PCIe storage device. The USB 3.1 Gen 2 interface offers data transfer speed up to 10Gbps, doubling the USB 3.1 Gen 1 data rate. Meanwhile, the downstream port of the JMS583 is compatible with storage device with PCIe interface, such as SSD. The PCIe port is compliant with PCIe Gen3 x 2 specifications

Introduction

The JMS583-QHFA0A 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-QHFA0A has USB Type-C TM connectivity built in to the controller that any device using the JMS583 can have

a Type-C 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-QHFA0A 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-QHFA0A 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 connectivity, the JMS583-QHFA0A 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, theJMS583-QHFA0A 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.
