Package Code Extraction

  • EFM32/EFR32: Single letter before dash (G=BGA) or full package name after dash (QFP100)
  • C8051: Suffix after dash (e.g., GQ)
  • SI parts: Suffix after last dash

Series Extraction

Returns human-readable series names:

  • "C8051", "EFM8 Busy Bee", "EFM8 Sleepy Bee", "EFM8 Laser Bee"
  • "EFM32 Giant Gecko", "EFM32 Wonder Gecko", "EFM32 Happy Gecko", "EFM32 Pearl Gecko"
  • "Blue Gecko", "Flex Gecko", "Mighty Gecko"
  • "Timing", "Environmental Sensor", "Proximity Sensor", "USB Bridge"
  • "Digital Isolator", "Isolated Gate Driver", "Bluetooth Module"

Replacement Logic

  • Must be same series for compatibility
  • Pin-compatible parts within same subfamily may be replaceable

Test Patterns

When testing SiliconLabsHandler:

  1. Use documentation tests for 
    matches()
    behavior
  2. Use assertions for 
    extractPackageCode()
    , 
    extractSeries()
    , null handling
  3. Instantiate directly: 
    new SiliconLabsHandler()
