Electrical Characteristics
A.1
This supplement contains the most accurate electrical information for the MC9S12Q128 microcontrollers
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
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
The MC9S12Q128 members utilize several pins to supply power to the I/O ports, A/D converter, oscillator
and PLL as well as the internal logic.
Freescale Semiconductor
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.

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