Frequently Asked Questions
What is the maximum interface speed of this eMMC?
The FEMDNN064G-A3A55 supports eMMC 5.1 HS400 mode with maximum interface speed of 400MB/s. Actual sequential read performance is up to 320MB/s and sequential write up to 90MB/s. The HS400 mode uses 8-bit parallel interface with DDR (Double Data Rate) operation at 200MHz clock frequency. This provides excellent performance for automotive boot and application loading requirements.
HS400 mode provides excellent performance for automotive infotainment boot and media storage.
Does this eMMC support power-loss protection?
Yes, the FEMDNN064G-A3A55 includes power-loss protection features to prevent data corruption during unexpected power events. The firmware implements sudden power-off recovery mechanisms to maintain data integrity. This is critical for automotive applications where power events can occur during engine cranking or electrical transients. The power-loss protection ensures filesystem consistency and prevents bricking of the storage device.
Power-loss protection is essential for automotive applications with potential power instability.
What is the endurance rating for automotive applications?
The FEMDNN064G-A3A55 is rated for 3,000 to 5,000 P/E (Program/Erase) cycles under typical automotive usage patterns. With Longsys advanced wear leveling algorithms, this translates to several years of service life in typical infotainment applications. For applications with higher write requirements, consider pSLC mode products or larger capacity devices which distribute writes across more NAND cells.
Endurance is sufficient for typical automotive infotainment read-heavy workloads.
What package options are available?
The FEMDNN064G-A3A55 is available in standard BGA-153 package with 11.5mm x 13mm x 1.0mm dimensions. The BGA-153 package is the industry standard for eMMC devices and is compatible with most automotive-grade PCB assembly processes. The package uses lead-free (RoHS compliant) solder balls with standard 0.5mm ball pitch for reliable surface mount assembly.
BGA-153 package is compatible with standard automotive PCB assembly processes.
What AEC-Q100 grade is this product qualified to?
The FEMDNN064G-A3A55 is qualified to AEC-Q100 Grade 2, which requires operation from -40°C to +105°C ambient temperature. This grade is suitable for automotive interior applications and some under-hood applications with appropriate thermal management. Grade 2 qualification includes rigorous testing for temperature cycling, high-temperature operating life, ESD protection, and mechanical shock.
AEC-Q100 Grade 2 is suitable for automotive interior and controlled under-hood applications.
