Preliminary Electrical Characteristics

This section contains electrical specification tables and reference timing diagrams for the MCF51JM128 microcontroller,
including detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications.
The electrical specifications are preliminary and are from previous designs or design simulations. These specifications may not
be fully tested or guaranteed at this early stage of the product life cycle. These specifications will, however, be met for
production silicon. Finalized specifications will be published after complete characterization and device qualifications have
been completed.
2.1
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:
2.2
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified in
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, V

Absolute Maximum Ratings
or V
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.
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.
Those parameters are derived mainly from simulations.
The parameters specified in this data sheet supersede any values found in the module
specifications.
The classification is shown in the column labeled C in the parameter tables where
appropriate.
