Refurbished eMMC Memory
eMMC is managed NAND flash with a controller in a single BGA package. Older versions such as eMMC 4.5 and 5.0 are discontinued at many manufacturers but remain in automotive, industrial and consumer products. AURCAL sources eMMC to order and tests it on dedicated eMMC machines.
- We source eMMC to order and state the condition on every quote.
- Parts are inspected, reballed where needed, tested and burned in at our Shenzhen base.
- The list below is reference data from public part lists, not our inventory.
Are eMMC versions compatible with each other?
eMMC is generally backward compatible at the interface level, but capacity, firmware, package size and ball map must also match your design. Confirm with the datasheet before substituting.
What should I match when replacing a discontinued eMMC?
Match the full part number first. Otherwise compare capacity, eMMC version (4.5, 5.0 or 5.1), package size and ball count, voltage, temperature range and firmware requirements.
Why does eMMC need functional testing?
An eMMC device contains a controller and NAND. A functional test checks that it can be read and written and that failures are separated from good stock.
Key differences
| Version | Fast interface mode | Notes |

| eMMC 4.5 | HS200 | Older, widely discontinued |
| eMMC 5.0 | HS400 | Common in automotive and industrial |
| eMMC 5.1 | HS400 with enhanced features | Newer designs |
