Appendix A Electrical Characteristics
A.10 Supply Currents
This section describes the current consumption characteristics of the device as well as the
conditions for the measurements.
A.10.1 Measurement Conditions
All measurements are without output loads. Unless otherwise noted the currents are measured in
single chip mode, internal voltage regulator enabled and at 25 MHz bus frequency using a 25 MHz
oscillator.
A.10.2 Additional Remarks
In expanded modes the currents flowing in the system are highly dependent on the load at the
address, data and control signals as well as on the duty cycle of those signals. No generally
applicable numbers can be given. A very good estimate is to take the single chip currents and add
the currents due to the external loads.

1 _{When calculating power consumption, the additional current sunk by the PHY_TXN and PHY_TXP pins must be taken into}
account. See Table A-8 for currents and voltages to use in the power calculations.
