This document contains electrical specification tables and reference timing diagrams for the MCF54455 microprocessor. This
section contains detailed information on DC/AC electrical characteristics and AC timing specifications.
The electrical specifications are preliminary and from previous designs or design simulations. These specifications may not be
fully tested or guaranteed at this early stage of the product life cycle. However, for production silicon, these specifications will
be met. Finalized specifications will be published after complete characterization and device qualifications have been
completed.

permanent damage to the device.
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
(e.g., V
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, and then use the larger of the two values.
All functional non-supply pins are internally clamped to V
Power supply must maintain regulation within operating EV
