Appendix A

Electrical Characteristics

This section contains electrical information for MAC7200 family microcontrollers. The information is

preliminary and subject to change without notice.

A.1

Parameter Classification

The electrical parameters shown in this appendix are derived by various methods. To provide a better

understanding to the designer, the following classification is used. Parameters are tagged accordingly in

the column labeled “C” of the parametric tables, as appropriate.

A.2

Absolute Maximum Ratings

Absolute maximum ratings are stress ratings only. Functional operation outside these maximums is not

guaranteed. Stress beyond these limits may affect reliability or cause permanent damage to the device.

MAC7200 family devices contain 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 example, either VSS5 or

VDD5).

Table A-1. Parametric Value Classification

Parameters guaranteed during production testing on each individual device.

Parameters derived by the design characterization and by measuring a statistically relevant

sample size across process variations.

Parameters derived by design characterization on a small sample size from typical devices

under typical conditions (unless otherwise noted). All values shown in the typical column

are within this classification, even if not so tagged.

Parameters derived mainly from simulations.
