Power-on Ramp Rate
This section describes the AC electrical specifications for the power-on ramp rate requirements. Controlling the maximum
Power-On Ramp Rate is required to avoid falsely triggering the ESD circuitry. The following table provides the power supply
ramp rate specifications.
2.2
Power Characteristics
The following table shows the power dissipations of the VDD supply for various operating core complex bus clock (CCB_clk)
frequencies versus the core, DDR data rate, and QUICC Engine block frequencies. Note that these numbers are based on design
estimates only and are preliminary. More accurate power numbers are available after the measurement on the silicon is
complete.

Note:
1. Ramp rate is specified as a linear ramp from 10 to 90%. If non-linear (for example, exponential), the maximum rate of change
from 200 to 500 mV is the most critical as this range may falsely trigger the ESD circuitry.
2. Over full recommended operating temperature range (see Table 3).
