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.
P: Those parameters are guaranteed during production testing on each individual device.
C: 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.
T: 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.
D: 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, PLL
and internal logic.
The VDDA, VSSA pair supplies the A/D converter.
The VDDX, VSSX pair supplies the I/O pins.
The VDDR, VSSR pair supplies the internal voltage regulator.
VDD1, VSS1, VDD2 and VSS2 are the supply pins for the digital logic.
VDDPLL, VSSPLL supply the oscillator and the PLL.
