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. I
DD
refers only to the current consumption on the internal power supply lines (V
DDINT
). The current
consumption at the I/O on the V
DDEXT
power supply is very much dependent on the particular connection of the device in the final system.
9
I
DD-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 V
DDINT
= maximum.
10
IDLE denotes the current consumption during execution of the IDLE instruction. Measured at V
DDINT
= maximum.
11
I
DD-PDOWN
represents the processor operation in full power-down mode with both core and peripheral clocks disabled. Measured at V
DDINT
= maximum.
12
I
AVDD
represents the power consumption of the analog system. Measured at AVDD = maximum.
13
The responsibility lies with the user to ensure that the device is operated in such a manner that the maximum allowable junction temperature is not exceeded.
