Handler Implementation Notes

Package Code Extraction

// LPC: Extract from FBD, FET, FHN, JBD, UK patterns
if (upperMpn.startsWith("LPC")) {
    // LPC1768FBD100 -> FBD100
    // Find where letters after digits start
    int numEnd = findLastDigit(mpn, "LPC".length()) + 1;
    if (numEnd < mpn.length()) {
        return mpn.substring(numEnd);
    }
}

// Kinetis: Package is between V and speed digit
// MK64FN1M0VLL12 -> VLL (LQFP100)
if (upperMpn.startsWith("MK")) {
    int vPos = upperMpn.indexOf('V');
    if (vPos > 0) {
        // Extract 3-letter package code after V
        return upperMpn.substring(vPos, Math.min(vPos + 4, upperMpn.length()));
    }
}

// i.MX: Complex - after variant letters
// MCIMX6Q5EYM10AC -> M (BGA)

Series Extraction

// LPC: Family is LPC + series digits
// LPC1768FBD100 -> LPC1768
// LPC55S69JBD100 -> LPC55S69

// Kinetis: MK + family + subseries
// MK64FN1M0VLL12 -> MK64
// MKL25Z128VLK4 -> MKL25

// S32K: Full model number
// S32K144 -> S32K144

Known Issues in Current Handler

1. HashSet usage: Line 80 uses new HashSet<>() - should use Set.of() for immutability
2. Op-amp attribution error: LM358, LM324, LM741 are Texas Instruments parts, NOT NXP
3. QorIQ pattern too broad: ^P[0-9]+.* may match unrelated parts
4. Missing patterns: PMV and BSS MOSFETs in matches() but not initializePatterns()
5. Package extraction incomplete: Only handles LPC and MCIMX, missing Kinetis, S32K, MOSFETs

Pattern Recommendations

// LPC - more specific
"^LPC[0-9]{3,4}[A-Z]?[A-Z]{2,3}[0-9]{2,3}.*"

// Kinetis K series
"^MK[0-9]{2}[A-Z]{0,2}[0-9]+V[A-Z]{2,3}[0-9]+$"

// Kinetis L series
"^MKL[0-9]{2}[A-Z][0-9]+V[A-Z]{2,3}[0-9]+$"

// S32K with optional suffix
"^S32K[0-9]{3}[A-Z]?.*"

// i.MX - starts with MCIMX or MIMX
"^(?:MC)?IMX[0-9][A-Z0-9]+.*"

Learnings & Edge Cases

• Nexperia spin-off: BC847/BC857 transistors and some MOSFETs are now Nexperia (spun off from NXP in 2017)
• LPC55 security: The "S" in LPC55S69 indicates TrustZone security support
• i.MX ordering: MCIMX prefix is for ordering, datasheets often use just IMX
• Kinetis F vs no-F: "F" in MK64F indicates floating-point unit (Cortex-M4F vs M4)
• Package number is pin count: In LPC, FBD100 means LQFP with 100 pins
