ADSP-BF522/ADSP-BF523/ADSP-BF524/ADSP-BF525/ADSP-BF526/ADSP-BF527
When programming OTP memory on the ADSP-BF522/
ADSP-BF524/ADSP-BF526 processors, the VPPOTP ball must
be set to the write value specified in the Operating Conditions
for ADSP-BF522/ADSP-BF524/ADSP-BF526 Processors on
Page 28. There is a finite amount of cumulative time that the
write voltage may be applied (dependent on voltage and junc-
tion temperature) to VPPOTP over the lifetime of the part.
Therefore, maximum OTP memory programming time for the
ADSP-BF522/ADSP-BF524/ADSP-BF526 processors is shown
in Table 30. The ADSP-BF523/ADSP-BF525/ADSP-BF527 pro-
cessors do not have a similar restriction.

ESD
(electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid
performance degradation or loss of functionality.
