Conclusion
Longsys Electronics automotive-grade eMMC products cover mainstream capacities such as 8GB-128GB, including two product grades: industrial wide temperature (-40-85℃) and automotive grade (AEC-Q104 Grade3), and officially entered the industrial control market and the automotive original equipment market.
Among them, the industrial wide temperature eMMC products offer three capacity options: 8GB, 16GB, and 32GB. Before the official release of the automotive-grade eMMC products, Longsys’ industrial-grade eMMC series had already been in mass production for over a year and a half in automotive aftermarket products. Millions of industrial-grade eMMC products have undergone verification through the complete seasonal changes from spring to winter, as well as stringent testing by customers at various stages and market scrutiny. The actual defect rate of the products is significantly lower than 50 DPPM.
Longsys designs and verifies its FORESEE automotive-grade eMMC products to fully comply with the AEC-Q104 requirements. The design service life exceeds 10 years, and the manufacturing process strictly adheres to the IATF16949 system’s requirements.
