Key Features

SDHC UHS-I Cards (32GB, 16GB, 8GB)

Support UHS104, a new ultra high speed SD interface compliant with the new SD Memory Card Standard Ver. 3.0 (SD 3.0) which supports SD interface bus speeds up to 104MB per sec. enabling the industry’s first SDHC card with a maximum read speed of 95MB per second and a write speed of 80MB per second.
Provide conventional SD interfaces—3.3V signal voltage for the DS mode (SD clock 25MHz and 12.5MB per sec) and the HS mode (SD clock 50MHz and 25MB per sec)—and are interoperable with existing SDHC host devices compliant with the SD Memory Card Standard Ver. 2.0 (SD 2.0).
Integrate highly secure CPRM copy protection technology.

microSDHC UHS-I Cards (16GB, 8GB, 4GB)

Support UHS50, a new ultra high speed SD interface compliant with the new SD 3.0 which supports SD interface bus speeds up to 50MB per second enabling the industry’s first microSD with a maximum read speed of 40MB per second and a write speed of 20MB per second.
Provide conventional SD interfaces—3.3V signal voltage for the DS mode (SD clock 25MHz and 12.5MB per second) and the HS mode (SD clock 50MHz and 25MB per second)—and are interoperable with existing microSDHC host devices compliant with SD 2.0.
Compliant with DDR 50 (SD Clock 50MHz) double data rate to achieve a bus transfer rate of 50MB/s compared with the existing HS mode at the same SD clock frequency.
Integrate highly secure CPRM copy protection technology.
