JMicron Technology MPN encoding patterns, series identification, and handler guidance. Use when working with storage controller ICs or JMicronHandler.
JMicron MPNs follow these general structures:
JMS[SERIES][VARIANT][PACKAGE] (USB-SATA bridges)
JMB[SERIES][VARIANT][PACKAGE] (PCIe/SATA controllers)
JMF[SERIES][VARIANT][PACKAGE] (Flash controllers)
JM20[SERIES][VARIANT][PACKAGE] (Legacy IDE/SATA)
| | | |
| | | └── Package code (QFN, LQFP, BGA, etc.)
| | └── Variant letter (optional)
| └── 3-digit series number
└── JMS/JMB/JMF/JM20 prefix
JMS583-QFN
│ │ │
│ │ └── QFN package
│ └── 583 = USB 3.1 Gen2 to SATA/NVMe bridge
└── JMS = JMicron USB-SATA prefix
JMB585-LQFP
│ │ │
│ │ └── LQFP package
│ └── 585 = 5-port PCIe Gen3 SATA controller
└── JMB = JMicron board controller prefix
