This section contains electrical specification tables and reference timing diagrams for the
MCF51EM256/128 series microcontrollers, 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.
2.1
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:

LQFP
These pins that are shared with the LCD are open-drain by default if not used as LCD pins. To configure this pins as full
complementary drive outputs, you must have the LCD modules bits configured as follow: FCDEN =1, VSUPPLY = 11 and RVEN
= 0. The Input levels and internal pullup resistors are referenced to VLL3. Referer to the LCD chapter for further information.
