Electrical Characteristics
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.
NOTE
The parameters specified in this MCU document supersede any values found in the module
specifications.

Absolute Maximum Ratings
Table 5. Absolute Maximum Ratings1, 2
1 Functional operating conditions are given in Table 8. Absolute maximum ratings are stress ratings only, and functional
operation at the maximum 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., VSS or EVDD).

calculate resistance values for positive and negative clamp voltages, and then use the larger of the two values.

4 All functional non-supply pins are internally clamped to V
SS and EVDD.
5 Power supply must maintain regulation within operating EV
DD range during instantaneous and operating maximum
current conditions. If positive injection current (Vin > EVDD) is greater than IDD, the injection current may flow out of EVDD
and could result in external power supply going out of regulation. Ensure the external EVDD load shunts current greater
than maximum injection current. This is the greatest risk when the MPU is not consuming power (ex; no clock). The power
supply must maintain regulation within operating EVDD range during instantaneous and operating maximum current
conditions.
