ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in the table 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.

When programming OTP memory on the ADSP-
BF522/524/526 processors, the VPPOTP ball must be set to the
write value specified in the

tive time that the write voltage may be applied (dependent on
voltage and junction temperature) to VPPOTP over the lifetime
of the part. Therefore, maximum OTP memory programming

this specification, if pins PH4, PH3, PH2, PH1, and PH0 from
group 1 in the
ing 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
