Electrical Characteristics
4.3
This section contains the i.MX31 and i.MX31L 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 pads of the i.MX31. There are two
main types of pads: regular and DDR. In this document, the “Regular” type is referred to as GPIO.
4.3.1.1
The i.MX31/i.MX31L pad I/O operating characteristics appear in
for DDR (Double Data Rate) pads.

3. Powering up of the remainder of noisy and PLL supplies, which can be done simultaneously. The
4. FUSE_VDD—the last supply to be powered up
order within the noisy supplies must be maintained, as follows:
a) Remainder of noisy supplies (all except for the NVCC2, 21,22, and NVCC1 supplies)
b) NVCC2, NVCC21, NVCC22.
