Electrical Characteristics
A.1
General
NOTE
The electrical characteristics given in this section should be used as a guide
only. Values cannot be guaranteed by Freescale until the qualication
process for this device has been nished.
Freescale reserves the right to make amendments to the electrical
characteristics quoted in this section. Freescale recommends subscribing to
device documentation at Freescale.com in order to stay informed of any
FURTHER changes to this Reference Manual.
This supplement contains the most accurate electrical information for the MC9S12XF-Family
microcontroller available at the time of publication.
This introduction is intended to give an overview on several common topics like power supply, current
injection etc.
A.1.1
Parameter Classication
The electrical parameters shown in this supplement are guaranteed by various methods. To give the
customer a better understanding the following classication is used and the parameters are tagged
accordingly in the tables where appropriate.
NOTE
This classication 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 MC9S12XF-Family 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 pin pairs supply the A/D converter and parts of the internal voltage regulator.
