Electrical Characteristics
4.2.2
The power-down sequence prior to silicon Revision 2.0 should be completed as follows:
For silicon revisions beginning with Revision 2.0 there is no special requirements for power down
sequence.
4.3
This section contains the MCIMX31 electrical information including timing specifications, arranged in
alphabetical order by module name.
4.3.1
This section specifies the AC/DC characterization of functional I/O of the MCIMX31. There are two main
types of I/O: regular and DDR. In this document, the “Regular” type is referred to as GPIO.
4.3.1.1
The MCIMX31 I/O parameters appear in
voltage ranges.

Parameter
The term NVCC in this section refers to the associated supply rail of an
input or output. The association is shown in the Signal Multiplexing chapter
of the reference manual. NVCC for
NVCC3–10; QVCC refers to QVCC, QVCC1, and QVCC4.
