...-maximum values for read and write currents at the VDD power supply are coded Table 3-22. The memory capacity of the card is computed from the entries C_SIZE, C_SIZE_MULT and READ_BL_LEN as follows: memory capacity = BLOCKNR * BLOCK_LEN Where: BLOCKNR = (C_SIZE+1) * MULT MULT = 2C_SIZE_MULT+2 BLOCK_LEN = ...currents on the card. The factor MULT is 4096*512*2048=4 GB.
