The specitica- tions are subject to change without notice. Verify with your local Intel Sales office that you have the latest data sheet before finalizing a design. *WARNING: Stressing the device beyond the Absolute Maximum Ratings" may cause permanent damage. These are stress ratings only. Operation beyond the Operating Conditions is not recommended and ex- tended exposure beyond the Operating Conditions" may affect device reliability.

Pins being floated during HOLD or by invoking the ONCE Mode. 2. Characterization conditions are a) Frequency = 1 MHz; b) Unmeasured pins at GND; c) Viy at + 5.0V or 0.46V. This parameter is not tested. 3. Current is measured with the device in RESET with X1 and X2 driven and all other non-power pina open 4. RB/OQSMD, UCS, (CS, MCS0/PEREQ, MCS1/ERROR and TEST/BUSY pins have internal pullup devices. Loading some of these pins above Io, = 200 1A can cause the processor to go into alternative modes of operation. See the section on Local Bus Controller and Reset for details. Power Supply Current Current is tinearly proportional to clock frequency and is measured with the device in RESET with X1 and X2 driven and all other non-power pins open. Maximum current is given by Icc = 5 mA X freq. (MHz) + Ig. la is the quiescent leakage current when the clock is static. Iq is typically less than 100 pA. 1-56 Ig (ma) 100 80 60 40 20 MAX 4 Clock Frequency (MHz) 12 16 20 272431-98 Figure 5. loc vs Frequency PRELIMINARY
