This section contains electrical specification tables and reference timing diagrams for the MCF5213
microcontroller unit. This section contains detailed information on power considerations, DC/AC
electrical characteristics, and AC timing specifications of MCF5213.
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.

Abbreviation
Dedicated power supply signals to isolate the sensitive PLL analog
circuitry from the normal levels of noise present on the digital power
supply.
These pins supply positive power to the core logic.
This pin is the negative supply (ground) to the chip.
