Specifications

3.2 Recommended Operating Range

Table 5 provides the recommended operating ranges for the supply voltages. The MC9328MXL 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 3 on page 6.

3.3 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 website page.
