ADSP-2104/ADSP-2109–SPECIFICATIONS
C AUT ION
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-2104/ADSP-2109 processor features proprietary ESD protection circuitry to dissipate
high energy electrostatic discharges (Human Body Model), permanent damage may occur to devices
subjected to such discharges. T herefore, proper ESD precautions are recommended to avoid
performance degradation or loss of functionality. Unused devices must be stored in conductive foam
or shunts, and the foam should be discharged to the destination socket before the devices are
removed. Per method 3015 of MIL -ST D-883, the ADSP-2104/ADSP-2109 processor has been
classified as Class 1 device.

*Stresses greater than those listed above may cause permanent damage to the
device. T hese are stress ratings only, and 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.
