MPN Structure

TMC[FAMILY][SERIES]-[PACKAGE][-SUFFIX]
|     |       |        |        |
|     |       |        |        +-- T = Tape and reel
|     |       |        +-- Package code (LA, TA, WA, BOB)
|     |       +-- 2-digit series within family (00-99)
|     +-- Family digit (2, 4, 5, 6, 7)
+-- TMC prefix (all Trinamic parts)

Example: TMC2209-LA
         |  |  | |
         |  |  | +-- LA = QFN package
         |  |  +-- 09 = Series number
         |  +-- 2 = Stepper driver family
         +-- TMC = Trinamic prefix

Example: TMC5160-TA-T
         |  |  | | |
         |  |  | | +-- T = Tape and reel packaging
         |  |  | +-- TA = TQFP package
         |  |  +-- 60 = Series (motion controller)
         |  +-- 5 = Motion controller family
         +-- TMC = Trinamic prefix

Replacement Compatibility

Trinamic parts are compatible when:

1. Same series number (TMC2209 vs TMC2209)
2. Same package (LA vs LA, TA vs TA)
3. Different packaging suffix (-T vs no suffix)

Pattern Matching

// All Trinamic parts start with TMC
if (!upperMpn.startsWith("TMC")) {
    return false;
}

// TMC21xx - Basic stepper drivers

// TMC22xx - Advanced stepper drivers

// TMC4xxx - Gate drivers / Motion controllers

Package Code Extraction

String extractPackageCode(String mpn) {
    String upperMpn = mpn.toUpperCase();

    // Check for breakout board first (longest match)
    if (upperMpn.contains("-BOB") || upperMpn.endsWith("BOB")) {
        return "Breakout Board";
    }

    // Package codes: -LA, -TA, -WA (with optional -T suffix)
    if (upperMpn.contains("-LA") || upperMpn.matches(".*LA(-T)?$")) {
        return "QFN";
    }
    if (upperMpn.contains("-TA") || upperMpn.matches(".*TA(-T)?$")) {
        return "TQFP";
    }
    if (upperMpn.contains("-WA") || upperMpn.matches(".*WA(-T)?$")) {
        return "WQFN";
    }

    // Check without hyphen separator
    if (upperMpn.endsWith("LA") || upperMpn.endsWith("LAT")) return "QFN";
    if (upperMpn.endsWith("TA") || upperMpn.endsWith("TAT")) return "TQFP";
    if (upperMpn.endsWith("WA") || upperMpn.endsWith("WAT")) return "WQFN";

    return "";
}

Series Extraction

String extractSeries(String mpn) {
    String upperMpn = mpn.toUpperCase();

    if (!upperMpn.startsWith("TMC")) {
        return "";
    }

    // Find where series number ends
    int seriesEnd = 3;  // Start after "TMC"
    for (int i = 3; i < upperMpn.length() && i < 7; i++) {
        if (Character.isDigit(upperMpn.charAt(i))) {
            seriesEnd = i + 1;
        } else {
            break;
        }
    }

    return upperMpn.substring(0, seriesEnd);  // e.g., "TMC2209"
}

Learnings & Edge Cases

• Analog Devices acquisition: Trinamic was acquired by Analog Devices in 2021, some new parts may use ADI branding
• BOB = development: "-BOB" suffix indicates breakout board, NOT a production package
• UART vs SPI: TMC2208/2209 use UART, TMC2130 uses SPI - NOT interchangeable without firmware changes
• StallGuard versions: StallGuard2 (TMC2130) and StallGuard4 (TMC2209) have different tuning parameters
• -T suffix: Tape and reel packaging, functionally identical to tube packaging
• TMC5xxx dual: TMC5041/5072 control TWO motors, TMC5130/5160 control ONE motor
• 3-phase vs stepper: TMC6xxx is for BLDC/PMSM motors, NOT stepper motors
