ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 17 may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions 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.

1 _{Applies to 100% transient duty cycle. For other duty cycles see Table 18.}
2 _{Applies only when VDDEXT is within specifications. When VDDEXT is outside speci-}
fications, the range is V_DDEXT ± 0.2.
3 _{Applies to signals SCL, SDA.}

1 _{Applies to all signal pins/balls with the exception of CLKIN, XTAL.}
2 _{The individual values cannot be combined for analysis of a single instance of}
overshoot or undershoot. The worst case observed value must fall within one of
the voltages specified and the total duration of the overshoot or undershoot
(exceeding the 100% case) must be less than or equal to the corresponding duty
cycle.
3 _{Duty cycle refers to the percentage of time the signal exceeds the value for the}
100% case. The is equivalent to the measured duration of a single instance of
overshoot or undershoot as a percentage of the period of occurrence.
When programming OTP memory on the ADSP-BF51x proces-
sor, the V_PPOTP pin/ball must be set to the write value specified in
the Operating Conditions on Page 20. There is a finite amount
of cumulative time that the write voltage may be applied
(dependent on voltage and junction temperature) to V_PPOTP over
the lifetime of the part. Therefore, maximum OTP memory pro-
gramming time for the processor is shown in Table 19.

Table 20 and Table 21 specify the maximum total source/sink
(I_OH/I_OL) current for a group of pins. Permanent damage can
occur if this value is exceeded. To understand this specification,
if pins PF9, PF8, PF7, PF6, and PF5 from Group 1 in Table 21
table were sourcing or sinking 2 mA each, the total current for
those pins would be 10 mA. This would allow up to 70 mA total
that could be sourced or sunk by the remaining pins in the
group without damaging the device. Note that the V_OH and V_OL
specifications have separate per-pin maximum current require-
ments as shown in the Electrical Characteristics table.
