Introduction
This chapter contains electrical and timing specifications for the MC9RS08KB12 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:
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 chapter.
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, VSS or VDD) or the programmable pull-up
resistor associated with the pin is enabled.
Table 2. Parameter Classifications
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.
