Appendix A Electrical Characteristics

A.1 General

NOTE: 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.

NOTE: 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 supplement contains the most accurate electrical information for the MC9S12C-Family microcontrollers available at the time of publication. The information should be considered PRELIMINARY and is subject 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.

NOTE: This classification will be added at a later release of the specification

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 MC9S12C-Family and MC9S12GC-Family members utilize several pins to supply power to the I/O ports, A/D converter, oscillator and PLL as well as the internal logic.

The VDDA, VSSA pair supplies the A/D 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 digital logic.

VDDPLL, VSSPLL supply the oscillator and the PLL.
