Electrical characteristics
This document contains electrical specification tables and reference timing diagrams for the MCF5441x microprocessor. This
section contains detailed information on AC/DC electrical characteristics and AC timing specifications.

Absolute maximum ratings
Table 6. Absolute maximum ratings1, 2
1 Functional operating conditions are given in Table 11. 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. Immunity to static and electrical fields 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.

SS and EVDD .
5 Power supply must maintain regulation within operating EV
DD, FBVDD, and SDVDD range during instantaneous and
operating maximum current conditions. If positive injection current (Vin > EVDD, FBVDD, or SDVDD) is greater than
IDD, the injection current may flow out of EVDD, FBVDD, or SDVDD and could result in external power supply going
out of regulation. Ensure the external EVDD, FBVDD, or SDVDD load shunts current greater than maximum injection
current. This is the greatest risk when the MPU is not consuming power (for example, no clock).
