Value

Performance

0x00

For Cards not reaching the 2.4MB/s minimum value

0x08

Class A: 2.4MB/s and is the lowest allowed value for MMCplus and MMCmobile(16x150kB/s)

0x0A

Class B: 3.0MB/s and is the next allowed value (20x150kB/s)

0x0F

Class C: 4.5MB/s and is the next allowed value (30x150kB/s)

0x14

Class D: 6.0MB/s and is the next allowed value (40x150kB/s)

0x1E

Class E: 9.0MB/s and is the next allowed value (60x150kB/s)

This is also the highest class which any MMCplus or MMCmobile card is needed to support in low bus

category operation mode (26MHz with 4bit data bus).

A MMCplus or MMCmobile card supporting any higher class than this have to support this class also

(in low category bus operation mode).

0x28

Class F: Equals 12.0MB/s and is the next allowed value (80x150kB/s)

0x32

Class G: Equals 15.0MB/s and is the next allowed value (100x150kB/s)

0x3C

Class H: Equals 18.0MB/s and is the next allowed value (120x150kB/s)

0x46

Class J: Equals 21.0MB/s and is the next allowed value (140x150kB/s)

This is also the highest class which any MMCplus or MMCmobile card is needed to support in mid bus

category operation mode (26MHz with 8bit data bus or 52MHz with 4bit data bus).

A MMCplus or MMCmobile card supporting any higher class than this have to support this Class (in

mid category bus operation mode) and Class E also (in low category bus operation mode)

0x50

Class K: Equals 24.0MB/s and is the next allowed value (160x150kB/s)

0x64

Class M: Equals 30.0MB/s and is the next allowed value (200x150kB/s)

0x78

Class O: Equals 36.0MB/s and is the next allowed value (240x150kB/s)

0x8C

Class R: Equals 42.0MB/s and is the next allowed value (280x150kB/s)

0xA0

Class T: Equals 48.0MB/s and is the last defined value (320x150kB/s)
