Specifications
This chapter covers power considerations, DC/AC electrical characteristics, and AC timing specifications. For additional
information, see the MSC711x Reference Manual.
Note:
The MSC7112 electrical specifications are preliminary and many are from design simulations. These specifications
may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized specifications will be
published after thorough characterization and device qualifications have been completed.
In calculating timing requirements, adding a maximum value of one specification to a minimum value of another specification
does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values
in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction.
Therefore, a “maximum” value for a specification never occurs in the same device with a “minimum” value for another
specification; adding a maximum to a minimum represents a condition that can never exist.
Table 2 describes the maximum electrical ratings for the MSC7112.
CAUTION
This device contains circuitry protecting against damage
due to high static voltage or electrical fields; however,
normal precautions should be taken to avoid exceeding
maximum voltage ratings. Reliability is enhanced if unused
inputs are tied to an appropriate logic voltage level (for
example, either GND or VDD).

Notes:
1.
Functional operating conditions are given in Table 3.
2.
Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the listed limits may affect device reliability or cause permanent damage.

Section 3.1, Thermal Design Considerations includes a formula for computing the chip junction temperature (TJ).
