Power consumption
The R0002 power consumption depends on three parameters:
The operating frequency
The operating voltage
The card state
In the following table the supply current and the power consumption of one R0002 for typical operat-
ing conditions are listed. These parameters are typical values to give system designers some hints,
all guaranteed parameters are listed in "Chapter 10.2: Electrical characteristics":
1
Host has stopped generation of clock pulses.
2
In the initialization phase. No access to the memory core.
