Supply Current Characteristics
Table A-11 lists the supply current characteristics for MAC72xx devices operating at 70 MHz.
All current measurements are without output loads. Unless otherwise noted the currents are measured in
single chip mode, internal voltage regulator enabled and at 70MHz bus frequency. Production testing
isperformed using a square wave signal at the EXTAL input.
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 good estimate is to take the single chip currents and add the currents due to the external loads.
