Appendix A Electrical Characteristics
A.1.10.2 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 single chip currents and add the currents due to the external loads.
