Freescale Semiconductor
Electrical Characteristics
4.2.2
Powering Down
For silicon revisions beginning with Revision 2.0.1 there is no special requirements for the power down
sequence.
4.3
Module-Level Electrical Specifications
This section contains the MCIMX31 electrical information including timing specifications, arranged in
alphabetical order by module name.
4.3.1
I/O Pad (PADIO) Electrical Specifications
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
DC Electrical Characteristics
The MCIMX31 I/O parameters appear in Table 14 for GPIO. See Table 8 for temperature and supply
voltage ranges.
NOTE
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 Table 14 refers to NVCC1 and
NVCC3–10; QVCC refers to QVCC, QVCC1, and QVCC4.
