Freescale Semiconductor
Electrical Characteristics
4.3
Module-Level Electrical Specifications
This section contains the i.MX31 and i.MX31L 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 i.MX31. 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 i.MX31/i.MX31L I/O parameters appear in
Table 11
for GPIO. See
Table 7, "Operating Ranges," on
page 12
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 11
refers to NVCC1 and
NVCC3–10; QVCC refers to QVCC, QVCC1, and QVCC4.
