Electrical Characteristics
This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing
specifications. For additional information, see the MSC8144E Reference Manual.
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.

Notes:
1.
Reserved signals should be disconnected for compatibility with future revisions of the device.
2.
For signals with same functionality in all modes the appropriate cells are empty.
3.
The choice between GPIO function and other function is by GPIO registers setup. For configuration details, see Chapter 23,
GPIO in the MSC8144E Reference Manual.
4.
Open-drain signal.
5.
Internal 20 K
Ω pull-up resistor.
6.
For signals with GPIO functionality, the open-drain and internal 20 K
Ω pull-up resistor can be configured by GPIO register
programming. See Chapter 23, GPIO of the MSC8144E Reference Manual for configuration details.
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).
