Recommended Operating Range
Table 4 provides the recommended operating ranges for the supply voltages and temperatures. The i.MXS
processor has multiple pairs of VDD and VSS power supply and return pins. QVDD and QVSS pins are
used for internal logic. All other VDD and VSS pins are for the I/O pads voltage supply, and each pair of
VDD and VSS provides power to the enclosed I/O pads. This design allows different peripheral supply
voltage levels in a system.
Because AVDD pins are supply voltages to the analog pads, it is recommended to isolate and noise-filter
the AVDD pins from other VDD pins.
For more information about I/O pads grouping per VDD, please refer to Table 2 on page 4.

Power Sequence Requirements
For required power-up and power-down sequencing, please refer to the "Power-Up Sequence" section of
application note AN2537 on the i.MX applications processor website.

1 A typical application with 30 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the ARM
core-that is, 7x GPIO, 15x Data bus, and 8x Address bus.
2 A worst-case application with 70 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the
ARM core-that is, 32x GPIO, 30x Data bus, 8x Address bus. These calculations are based on the core running its heaviest OS
application at 100MHz, and where the whole image is running out of SDRAM. QVDD at 1.9V, NVDD and AVDD at 3.3V,
therefore, 180mA is the worst measurement recorded in the factory environment, max 5mA is consumed for OSC pads, with
each toggle GPIO consuming 4mA.
