ESD SENSITIVITY
TIMING SPECIFICATIONS
This section contains timing information for the DSP’s
external signals.
Programmable Flags Cycle Timing
Table 35
and
Figure 13
describe Programmable Flag operations.
The signals indicated are asynchronous and are not tied to any
clock.

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.
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-2192M 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 perfor-
mance degradation or loss of functionality.
