Appendix A Electrical Characteristics

A.1 General

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.

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.

A.1.2 Power Supply

The MC9S12DT128B utilizes several pins to supply power to the I/O ports, A/D converter, oscillator and

PLL as well as the digital core.

The VDDX, VSSX, VDDR and VSSR pairs supply the I/O pins ,VDDR supplies also 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.

VSS1 and VSS2 are internally connected by metal.

VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for ESD

protection.
