Table 17. EzPort Signal Descriptions
1.19 Power and Ground Pins
The pins described in
Table 18
provide system power and ground to the chip. Multiple pins are provided
for adequate current capability. All power supply pins must have adequate bypass capacitance for
high-frequency noise suppression.

Preliminary Electrical Characteristics
This section contains electrical specification tables and reference timing diagrams for the MCF52223
microcontroller unit. This section contains detailed information on power considerations, DC/AC
electrical characteristics, and AC timing specifications of MCF52223.
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 appendix supersede any values found in the
module specifications.
