Preliminary Electrical Characteristics

This document contains electrical specification tables and reference timing diagrams for the MCF5373

microcontroller unit. This section contains detailed information on power considerations, DC/AC

electrical characteristics, and AC timing specifications of MCF5373.

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, however

for production silicon these specifications will be met. Finalized specifications will be published after

complete characterization and device qualifications have been completed.

NOTE

The parameters specified in this MCU document supersede any values

found in the module specifications.

Maximum Ratings

NOTES:

1

Functional operating conditions are given in Section 5.4, “DC Electrical Specifications.”

Absolute maximum ratings are stress ratings only, and functional operation at the maxima is

not guaranteed. Continued operation at these levels may affect device reliability or cause

permanent damage to the device.

2

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.,
