Electrical Characteristics
3.1
Introduction
This section contains electrical and timing specifications for the MC9S08QE8 series of microcontrollers available at the time
of publication.
3.2
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:
Table 2. Parameter Classifications
Those parameters are guaranteed during production testing on each individual device.
P
C
Those parameters are achieved by the design characterization by measuring a statistically relevant
sample size across process variations.
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.
T
Those parameters are derived mainly from simulations.
D
NOTE
The classification is shown in the column labeled “C” in the parameter
tables where appropriate.
3.3
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified in Table 3 may affect device reliability or cause permanent damage to the device. For functional operating
conditions, refer to the remaining tables in this section.
This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised
that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this
high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for
instance, either V or V ) or the programmable pullup resistor associated with the pin is enabled.
