Appendix A Electrical Characteristics
A.1 General
NOTE
The electrical characteristics given in this section 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 MC9S12XE-Family
microcontroller available at the time of publication.
This introduction is intended to give an overview on several common topics like power supply, current
injection etc.
A.1.1 Parameter Classiï¬cation
The electrical parameters shown in this supplement are guaranteed by various methods. To give the
customer a better understanding the following classiï¬cation is used and the parameters are tagged
accordingly in the tables where appropriate.
NOTE
This classiï¬cation is shown in the column labeled âCâ 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.
T: Those parameters are achieved 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 category.
D: Those parameters are derived mainly from simulations.
A.1.2 Power Supply
The MC9S12XE-Family 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 pin pairs supply the A/D converter and parts of the internal voltage regulator.
The VDDX, VSSX pin pairs [7:1] supply the I/O pins.
VDDR supplies the internal voltage regulator.
