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-2189M 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.
TIMING PARAMETERS
GENERAL NOTES
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add up parameters to derive longer times.
TIMING NOTES
Switching characteristics specify how the processor changes its
signals. You have no control over this timing—circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics tell you what the
processor will do in a given circumstance. You can also use
switching characteristics to ensure that any timing requirement
of a device connected to the processor (such as memory) is
satisfied.
Timing requirements apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the proces-
sor operates correctly with other devices.
REV. A
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only; functional operation of the
device at these or any other conditions above 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.
Applies to Bidirectional pins (D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0,
TFS1, A1–A13, PF0–PF7) and Input only pins (CLKIN, RESET, BR, DR0,
DR1, PWD).
Applies to Output pins (BG, PMS, DMS, BMS, IOMS, CMS, RD, WR, PWDACK,
A0, DT0, DT1, CLKOUT, FL2-0, BGH).
