MC2GH256NMCA-2SA00 SAMSUNG [Samsung semiconductor], MC2GH256NMCA-2SA00 Datasheet - Page 35

• Manufacturer Part Number: MC2GH256NMCA-2SA00
• Description: SAMSUNG MultiMediaCard
• Manufacturer: SAMSUNG [Samsung semiconductor]

• PWR_CL_ff_vvv
These fields define the supported power classes by the card. By default, the card has to operate at maximum frequency
using 1 bit bus configuration, within the default max current consumption, as stated in the table below. If 4 bit/8 bits bus
configurations, require increased current consumption, it has to be stated in these registers.
By reading these registers the host can determine the power consumption of the card in different bus modes. Bits [7:4]
code the current consumption for the 8 bit bus configuration. Bits [3:0] code the current consumption for the 4 bit bus con-
figuration
The PWR_52_vvv registers are not defined for 26MHz MultiMediaCards.
The measurement for max RMS current is done as average RMS current consumption over a period of 100ms.
Max peak current is defined as absolute max value not to be exceeded at all.
The conditions under which the power classes are defined are:
These registers define the maximum power consumption for any protocol operation in data transfer mode, Ready state
and Identification state.
