Appendix A Electrical Characteristics
A.1.10
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
A.1.10.1
All measurements are without output loads. Unless otherwise noted the currents are measured in single
chip mode, internal voltage regulator enabled and at 16MHz bus frequency using a 4MHz oscillator in
Colpitts mode. Production testing is performed using a square wave signal at the EXTAL input.
A.1.10.2
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.

Maximum leakage current occurs at maximum operating temperature. Current decreases by approximately one-half for each
8 C to 12 C in the temper ature range from 50 C to 125 C .
