1 Applies to all input and bidirectional pins.
2 Applies to input pins CLKIN, RESET, TRST.
3 Applies to all output and bidirectional pins.
4 Applies to all input only pins.
5 Applies to input pins with internal pull-down.
6 Applies to input pins with internal pull-up.
7 Applies to three-stateable pins.
8 The I
DD supply currents are affected by the operating frequency of the device. The guaranteed numbers are based on an assumed CCLK = 160 MHz, HCLK = 80 MHz
for the ADSP-21990BST. 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 VDDINT = maximum.
10IDLE denotes the current consumption during execution of the IDLE instruction. Measured at VDDINT = maximum.
11IDD-PDOWN represents the processor operation in full power-down mode with both core and peripheral clocks disabled. Measured at VDDINT = maximum
12IAVDD represents the power consumption of the analog system. Measured at AVDD = maximum.
13The 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.
