Maximum Supply Current Consumption at VCC = 2.7 V
VDD_R_CURR_MIN / VDD_W_CURR_MIN
2:0
Code for current consumption at 2.7 V
2:0 0 = 0.5 mA; 1 = 1 mA; 2 = 5 mA;
3 = 10 mA; 4 = 25 mA; 5 = 35 mA;
6 = 60 mA; 7 = 100 mA
VDD_R_CURR_MAX, VDD_W_CURR_MAX
The maximum supply current at the maximum supply voltage VCC (3.6 V) is coded as follows:
Maximum Supply Current Consumption at VCC = 3.6 V
VDD_R_CURR_MAX / VDD_W_CURR_MAX
2:0
Code for current consumption at 3.6 V
0 = 1 mA; 1 = 5 mA; 2 = 10 mA; 3 = 25 mA;
4 = 35 mA; 5 = 45 mA; 6 = 80mA; 7 = 200 mA
C_SIZE_MULT
This parameter is used for coding a factor MULT for computing the total device size (refer to ‘C_SIZE)
The factor MULT is defined as 2
C_SIZE_MULT+2
.
ERASE_GRP_SIZE
The contents of this register are a 5bit binary coded value, used to calculate the size of the erasable unit
of these MultimediaCard. The size of the erase unit (also referred to as erase group in chapter “memory
Array Partitioning”) is determined by the ERASE_GRP_SIZE and the ERASE_GRP_MULT entries of the
CSD
Size of erasable unit = (ERASE_GRP_SIZE + 1) * (ERASE_GRP_MULT + 1)
The following table shows the size of erase group for each model.

ERASE_GRP_MULT
A 5bit binary coded value is used for calculating the size of the erasable unit of these MultiMediaCards.
The parameter ERASE_GRP_MULT is permanently assigned to the value 0x1F. See
ERASE_GRP_SIZE section for detailed description.
