Macronix serial flash uses a special encoding where the first 2-4 digits represent density:
| Code | Density | Bytes |
|---|---|---|
| 6433, 6435 | 64 Mbit | 8 MB |
| 12833, 12835 | 128 Mbit | 16 MB |
| 25635, 25645 | 256 Mbit | 32 MB |
| 51235, 51245 | 512 Mbit | 64 MB |
| 1G | 1 Gbit | 128 MB |
| 2G | 2 Gbit | 256 MB |
| Raw Code | Actual Density | Notes |
|---|---|---|
| 256 | 256 Mbit | Direct encoding (MX29GL) |
| 128 | 128 Mbit | Direct encoding (MX29GL) |
| 640 | 64 Mbit | Scaled encoding (MX29LV) |
| 320 | 32 Mbit | Scaled encoding (MX29LV) |
| 160 | 16 Mbit | Scaled encoding (MX29LV) |
| 800 | 8 Mbit | Scaled encoding (MX29LV) |
Important: MX29LV series uses scaled encoding (multiply by 0.1 for Mbits), while MX29GL uses direct encoding.

The MacronixHandler supports:
ComponentType.MEMORY
ComponentType.MEMORY_FLASH
Note: Unlike some handlers, MacronixHandler does not define manufacturer-specific types like MEMORY_FLASH_MACRONIX. Both patterns register to MEMORY and MEMORY_FLASH base types.
The handler extracts package codes differently based on the flash family:
Serial NOR (MX25L/U/R/V, MX66L):
// Example: MX25L6433FMI-08G
// F is at index 10, MI is at 11-12
// Returns "SOP-8"
Parallel NOR (MX29GL, MX29LV):
// Example: MX29GL256FHT2I-90Q
// HT follows density and F
// Returns "TSOP-48"
NAND (MX30LF):
// Example: MX30LF1G18AC
// AC is the suffix
// Returns "TSOP-48"
Returns the family prefix including the series letter:
| MPN | Series |
|---|---|
| MX25L6433FMI-08G | MX25L |
| MX25U12835FMI-10G | MX25U |
| MX66L1G45GMI-10G | MX66L |
| MX29GL256FHT2I-90Q | MX29GL |
| MX29LV640EBTI-70Q | MX29LV |
| MX30LF1G18AC | MX30LF |
The extractDensity() method (Macronix-specific helper) returns the decoded density:
| MPN | Extracted Density |
|---|---|
| MX25L6433F | 64 |
| MX25L12835F | 128 |
| MX29GL256 | 256 |
| MX29LV640 | 64 |
| MX30LF1G18AC | 1G |
