Appendix A Electrical Characteristics

A.1 General

NOTE:

The electrical characteristics given in this section are preliminary and should be

used as a guide only. Values cannot be guaranteed by Freescale and are subject to

change without notice.

This supplement contains the most accurate electrical information for the MC9S12KG128 microcontroller

available at the time of publication. The information should be considered PRELIMINARY and is subject

to change.

This introduction is intended to give an overview on several common topics like power supply, current

injection etc.

A.1.1 Parameter Classification

The electrical parameters shown in this supplement are guaranteed by various methods. To give the

customer a better understanding the following classification is used and the parameters are tagged

accordingly in the tables where appropriate.

NOTE:

This classification is shown in the column labeled “C” in the parameter tables

where appropriate.

Those parameters are guaranteed during production testing on each individual device.

Those parameters are achieved by the design characterization by measuring a statistically relevant

sample size across process variations. They are regularly verified by production monitors.

Those parameters are achieved by design characterization on a small sample size from typical

devices. All values shown in the typical column are within this category.

Those parameters are derived mainly from simulations.

A.1.2 Power Supply

The MC9S12KG128 utilizes several pins to supply power to the I/O ports, A/D converter, oscillator and

PLL as well as the digital core.

The VDDA, VSSA pair supplies the A/D converter.

The VDDX, VSSX pair supplies the I/O pins
