Appendix A Electrical Characteristics
A.1 General
This supplement contains the most accurate electrical information for the MC9S12E-Family
microcontroller available at the time of publication. The information should be considered
PRELIMINARY
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.
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 MC9S12E-Family 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 and D/A 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 internal logic.
VDDPLL, VSSPLL supply the oscillator and the PLL.

range, generally the electrical specifications for the 3.3V range apply, but the part
is not tested in production test in the intermediate range.
This classification will be added at a later release of the specification
The part is specified and tested over the 5V and 3.3V ranges. For the intermediate
