Adding New Memory Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.MEMORY, "^NEWMEM[0-9].*");
registry.addPattern(ComponentType.MEMORY_FLASH, "^NEWMEM[0-9].*");
registry.addPattern(ComponentType.MEMORY_MANUFACTURER, "^NEWMEM[0-9].*");
- Add to
getSupportedTypes():
types.add(ComponentType.MEMORY);
types.add(ComponentType.MEMORY_FLASH);
types.add(ComponentType.MEMORY_MANUFACTURER);
Similarity Calculation
MemorySimilarityCalculator compares:
- Memory type (Flash, EEPROM, SRAM)
- Density/capacity
- Interface (SPI, I2C, parallel)
- Voltage range
- Speed grade
- Package
Package Codes
| Code | Package | |------|---------| | SIQ | SOIC-8 150mil | | SIG | SOIC-8 208mil | | DIQ | DFN-8 | | CIQ | WSON-8 | | BIQ | BGA | | PIQ | PDIP-8 |
Memory Type Detection
The library can detect memory types from MPN patterns:
// Detect flash memory
ComponentType type = ComponentType.fromMPN("W25Q128JVSIQ");
// Returns MEMORY_FLASH_WINBOND
// Detect EEPROM
ComponentType type = ComponentType.fromMPN("AT24C256");
// Returns MEMORY_EEPROM or MEMORY_ATMEL
