Introduction

This chapter contains electrical and timing specifications for the MC9S08QA4 series of microcontrollers available at the time

of publication.

3.2

Absolute Maximum Ratings

Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the

limits specified in Table 2 may affect device reliability or cause permanent damage to the device. For functional operating

conditions, refer to the remaining tables in this section.

This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised

that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this

high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for

3.3

Thermal Characteristics

This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power

dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and voltage regulator circuits, and

no system clock is present, or if the clock rate is very low (which would reduce overall power

consumption).
