9 Applies to three-statable pins: DATA47–16, ADDR23–0, MS3–0, CLKOUT, FLAG11–0, REDY, HBG, BMS, BR6–1, RAS, CAS, SDWE, DQM,

SDCLKx, SDCKE, SDA10, BRST.

10Applies to three-statable pins with 20 kΩ pull-ups: RD, WR, DMAG1, DMAG2, PA.

11Applies to three-statable pins with 50 kΩ internal pull-ups: DxA, DxB, SCLKx, SPICLK., EMU, MISO, MOSI

12Applies to three-statable pins with 50 kΩ internal pull-downs: LxDAT7–0 (below Revision1.2), LxCLK, LxACK. Use IOZHPD2 for Rev. 1.2 and higher.

13Applies to three-statable pins with 20 kΩ internal pull-downs: LxDAT7-0 (Revision 1.2 and higher).

14The test program used to measure IDDINPEAK 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. For more information, see “Power Dissipation” on Page 21.

15Current numbers are for VDDINT and AVDD supplies combined.

16IDDINHIGH is a composite average based on a range of high activity code. See Power Dissipation on Page 21.

17IDDINLOW is a composite average based on a range of low activity code. See Power Dissipation on Page 21.

18Idle denotes ADSP-21161N state during execution of IDLE instruction. See Power Dissipation on Page 21.

19Characterized, but not tested.

20Applies to all signal pins.

21Guaranteed, but not tested.

1 Stresses greater than those listed above may cause permanent damage to the

device. These are stress ratings only; functional operation of the device at these

or any other conditions greater than those indicated in the operational sections

of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

ESD SENSITIVITY

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V

readily accumulate on the human body and test equipment and can discharge without

detection. Although the ADSP-21161N features proprietary ESD protection circuitry,

permanent damage may occur on devices subjected to high energy electrostatic

discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
