eMMC

The following tables describe the eMMC. The test conditions for eMMC standard mode use an 8 mA drive

strength, fast slew rate, and a 30 pF load (I/O voltage of 3 V/1.8 V/1.2 V). For eMMC high-speed mode, the

test conditions use a 12 mA drive strength, fast slew rate, and 30 pF load (I/O voltage of 3 V/1.8 V/1.2 V).

For other eMMC modes, the test conditions use a 12 mA drive strength, fast slew rate, and 15 pF load (I/O

voltage of 1.8 V/1.2 V)
