This section contains electrical specification tables and reference timing diagrams for the
MCF51MM256/128 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.
3.1
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:
3.2
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not
guaranteed. Stress beyond the limits specified in the following table may affect device reliability or cause
permanent damage to the device. For functional operating conditions, refer to the remaining tables in this
section.

Parameter Classification
Absolute Maximum Ratings
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.
