Electrical Characteristics

This document contains electrical specification tables and reference timing diagrams for the MCF5373 microcontroller unit.

This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing

specifications of MCF5373.

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 MCU document supersede any values found in the module

specifications.

Maximum Ratings

Table 4. Absolute Maximum Ratings1, 2

1 Functional operating conditions are given in Section 5.4, “DC Electrical Specifications.”

Absolute maximum ratings are stress ratings only, and functional operation at the maxima 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 (VSS or

EVDD).

3 Input must be current limited to the value specified. To determine the value of the required

current-limiting resistor, calculate resistance values for positive and negative clamp voltages,

and then use the larger of the two values.

VIN

– 0.3 to +3.6

Instantaneous Maximum Current

Single pin limit (applies to all pins) 3, 4, 5

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 external EVDD load shunts current greater than maximum injection

current. This is the greatest risk when the MCU is not consuming power (ex; no clock). Power

supply must maintain regulation within operating EVDD range during instantaneous and

operating maximum current conditions.
