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
- HashSet usage: Line 80 uses
new HashSet<>()- should useSet.of()for immutability - Op-amp attribution error: LM358, LM324, LM741 are Texas Instruments parts, NOT NXP
- QorIQ pattern too broad:
^P[0-9]+.*may match unrelated parts - Missing patterns: PMV and BSS MOSFETs in matches() but not initializePatterns()
- 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
