## Handler Implementation Notes

### Package Code Extraction

```java
// ABLIC package codes are single letters
// Position varies by product type
// For LDOs: S-1167B33A -> A after voltage code
// For EEPROM: S-24C02A -> A after density

// LDO pattern: S-[0-9]+[variant][voltage]([package])
Pattern packagePattern = Pattern.compile("^S-[0-9]+[A-Z]*[0-9]{2,3}([ABUNCTSF]).*$");

// EEPROM pattern: S-[0-9]+C[0-9]+([package])
Pattern eepromPattern = Pattern.compile("^S-[0-9]+C[0-9]+([A-Z]).*$");
```

### Series Extraction

```java
// Different series have different length numbers
// S-1xxx (4 digits), S-80xxx (5 digits), S-35xxx (5 digits)
// S-82xx/S-82xxx (4-5 digits), S-24C/S-93C (prefix only)

if (upperMpn.matches("^S-1[0-9]{3}.*")) {
    return upperMpn.substring(0, 6);  // S-1167, S-1206
}
if (upperMpn.matches("^S-80[0-9]{3}.*")) {
    return upperMpn.substring(0, 7);  // S-80740, S-80945
}
if (upperMpn.matches("^S-35[0-9]{3}.*")) {
    return upperMpn.substring(0, 7);  // S-35390, S-35198
}
if (upperMpn.matches("^S-24C[0-9]+.*")) {
    return "S-24C";  // I2C EEPROM series
}
if (upperMpn.matches("^S-93C[0-9]+.*")) {
    return "S-93C";  // Microwire EEPROM series
}
```

### Product Type Detection

```java
public boolean isLDORegulator(String mpn) {
    return mpn.matches("^S-1[0-9]{3}[A-Z0-9-]*$");
}

public boolean isVoltageDetector(String mpn) {
    return mpn.matches("^S-80[0-9]{3}[A-Z0-9-]*$") ||
           mpn.matches("^S-8[07]9[0-9]{2}[A-Z0-9-]*$");
}

public boolean isRTC(String mpn) {
    return mpn.matches("^S-35[0-9]{3}[A-Z0-9-]*$");
}

public boolean isBatteryManagement(String mpn) {
    return mpn.matches("^S-82[0-9]{2,3}[A-Z0-9-]*$");
}

public boolean isEEPROM(String mpn) {
    return mpn.matches("^S-24C[0-9]+.*") ||
           mpn.matches("^S-93C[0-9]+.*");
}

public boolean isI2CEEPROM(String mpn) {
    return mpn.matches("^S-24C[0-9]+[A-Z0-9-]*$");
}

public boolean isMicrowireEEPROM(String mpn) {
    return mpn.matches("^S-93C[0-9]+[A-Z0-9-]*$");
}
```

### Supported Component Types

```java
// ABLIC handler supports:
// - IC (all parts)
// - VOLTAGE_REGULATOR (S-1xxx LDOs, S-80xxx detectors)
// - MEMORY (S-24Cxx, S-93Cxx EEPROMs)
// - MEMORY_EEPROM (S-24Cxx, S-93Cxx EEPROMs)

// Note: RTC (S-35xxx) and Battery Management (S-82xx) are classified as IC only

## Learnings & Edge Cases

- **S- prefix is mandatory**: All ABLIC parts start with "S-" - don't confuse with other S-prefixed manufacturers
- **Formerly Seiko Instruments (SII)**: ABLIC was spun off from SII in 2016, legacy parts may have SII branding
- **Ultra-low power focus**: ABLIC specializes in battery-powered and IoT applications
- **Voltage detectors as regulators**: S-80xxx voltage detectors are classified as VOLTAGE_REGULATOR
- **EEPROM interface types**: S-24Cxx uses I2C, S-93Cxx uses Microwire (3-wire SPI-like)
- **Complex suffix structure**: Suffixes like "-I6T1U" encode grade, tape/reel, and package options
- **Package code position varies**: For LDOs it's after voltage code, for EEPROM it's after density
- **Real-Time Clocks not in VOLTAGE_REGULATOR**: S-35xxx RTCs are IC type only
- **Battery management ICs**: S-82xx parts are for Li-ion protection/fuel gauge, classified as IC
