MPN Structure

ASMedia MPNs follow this general structure:

ASM[SERIES][VARIANT][PACKAGE][-REEL]
  |    |       |        |       |
  |    |       |        |       └── Optional: REEL, TRAY, TR for packaging
  |    |       |        └── Package code (QFN, BGA, LQFP, or single letter)
  |    |       └── Revision letter (A, B, etc.)
  |    └── 4-digit series number (1xxx, 2xxx, 3xxx)
  └── ASMedia prefix

Example Decoding

ASM1042A-QFN
│  │   │  │
│  │   │  └── QFN package
│  │   └── A revision
│  └── 1042 = PCIe to USB 3.0 host controller
└── ASM = ASMedia prefix

ASM2364-BGA
│  │   │
│  │   └── BGA package
│  └── 2364 = USB 3.2 Gen2x2 to NVMe bridge
└── ASM = ASMedia prefix

Handler Implementation Notes

Pattern Matching

// ASM1xxx series - USB 3.x controllers and bridges
"^ASM1[0-9]{3}[A-Z]*.*"

// ASM2xxx series - SATA controllers
"^ASM2[0-9]{3}[A-Z]*.*"

// ASM3xxx series - USB4/Thunderbolt controllers
"^ASM3[0-9]{3}[A-Z]*.*"

// Generic pattern for all ASM parts
"^ASM[0-9]{4}[A-Z]*.*"

Series Extraction

// Series is always "ASM" + 4 digits
// ASM1042A-QFN -> ASM1042
// ASM2364 -> ASM2364

if (mpn.length() >= 7) {
    return mpn.substring(0, 7);  // Returns "ASM1042"
}

Package Code Extraction

// Check for explicit package suffix after hyphen
// ASM1042-QFN -> QFN
int hyphen = cleanMpn.indexOf('-');
if (hyphen > 0) {
    String suffix = cleanMpn.substring(hyphen + 1);
    // Map to package name
}

// Or extract trailing letter after digits
// ASM1042Q -> QFN (Q maps to QFN)

Replacement Compatibility

USB Generation Upgrades

USB 3.1 Gen2 controllers can replace USB 3.0 (backward compatible):

• ASM1142 can replace ASM1042

Bridge Family Compatibility

Same-generation bridges are compatible:

• ASM1153 and ASM1156 are interchangeable (USB 3.0 to SATA family)

Learnings & Edge Cases

• All ASMedia parts use single IC type: Unlike other manufacturers, ASMedia only produces controller ICs, no discrete components
• Series numbering scheme: 1xxx = USB, 2xxx = Storage/NVMe, 3xxx = USB4/Thunderbolt
• USB generation embedded in series: ASM10xx = USB 3.0, ASM11xx = USB 3.1
• Package codes can appear after hyphen or as trailing letter: Both ASM1042-QFN and ASM1042Q are valid
• REEL/TRAY/TR suffixes: Indicate packaging type, should be stripped before package extraction
