Appendix A Electrical Characteristics
A.1 General
This supplement contains the most accurate electrical information for the MC9S12DT256 microcontroller
available at the time of publication. The information should be considered
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.

A.1.2 Power Supply
The MC9S12DT256 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 and the resistor ladder of the internal voltage regulator.
NOTE:
NOTE:
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.
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.
Those parameters are derived mainly from simulations.
The electrical characteristics given in this section are preliminary and should be
used as a guide only. Values cannot be guaranteed by Motorola and are subject to
change without notice.
This classification is shown in the column labeled “C” in the parameter tables
where appropriate.
