IDD-PEAK
Supply Current (Internal)
8, 9
8 The I
DD supply currents are affected by the operating frequency of the device. The guaranteed numbers are based on an assumed CCLK = 150 MHz, HCLK = 75 MHz
for the ADSP-21990BBC. IDD refers only to the current consumption on the internal power supply lines (VDDINT). The current consumption at the I/O on the VDDEXT
power supply is very much dependent on the particular connection of the device in the final system.
9 IDD-PEAK represents worst-case processor operation and is not sustainable under normal application conditions. Actual internal power measurements made using typical
applications are less than specified. Measured at VDDIINT = maximum.
