Appendix A Electrical Characteristics
A.1 General
NOTE: The part is 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 part
is not tested in production test in the intermediate range.
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.
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 MC9S12B128 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 the internal voltage regulator.
The VDDX, VSSX, VDDR and VSSR pairs supply the I/O pins, VDDR supplies also the internal voltage
regulator.
