9.3 Power Consumption
This section details the power consumption of the device as measured during various modes of
operation. Power dissipation is determined by temperature, supply voltage, and external source/sink
requirements.
9.3.1 Operational / Unconfigured
9.3.2 Suspend / Standby
Note: Typical values measured with VDD33 = 3.3V. Maximum values measured with VDD33 = 3.6V.

9.5 AC Specifications
This section details the various AC timing specifications of the device.
9.5.1 Power-On Configuration Strap Valid Timing
Figure 9.2 illustrates the configuration strap timing requirements, in relation to power-on, for
applications where RESET_N is not used at power-on. The operational level (V
opp
) for the external
power supply is detailed in Section 9.2, "Operating Conditions**," on page 42.
Note: For RESET_N configuration strap timing requirements, refer to Section 9.5.2, "Reset and
Configuration Strap Timing," on page 46.
