Silicon Errata Issues
1.
Module: Data EE Memory
1.1 Data EE Memory Endurance
The typical write/erase endurance of the data EE
memory is limited to 10k cycles.
Work around
Use error correction method that stores data in
multiple locations.
Affected Silicon Revisions
1.2 Data EE Write at Min. VDD
The minimum voltage required for a data EE write
operation is 2.0 volts.
Work around
None.
Affected Silicon Revisions
2.
Module: Program Flash Memory (PFM)
2.1 Program Flash Memory Endurance
The typical write/erase endurance of the PFM is
limited to 1k cycles when VDD is above 3.0 volts.
Endurance degrades when VDD is below 3V.
Work around
Use an error correction method that stores data
in multiple locations.
Affected Silicon Revisions
2.2 Program Flash Memory Writes at Min. VDD
The minimum voltage required for a PFM write
operation is 2.0V.
Work around
None.
Affected Silicon Revisions
3.
Module: Capture Compare PWM (CCP)
3.1 Dead-Band Delay
With the ECCP configured for PWM Half-Bridge
mode and a dead-band delay greater than or equal
to the PWM duty cycle; unpredictable waveforms
will result.
Work around
Make sure the dead-band delay is always less
than the PWM duty cycle.
Affected Silicon Revisions
3.2 ECCP2 Switching Between Single, Half-
Bridge and Full-Bridge PWM modes
Switching PWM mode during the current PWM
cycle by modifying the P2M<1:0> bits in the
CCP2CON register will cause the PWM outputs to
switch immediately and not on the start of the next
PWM cycle.
Work around
None.
Affected Silicon Revisions
3.3 ECCP2 Changing Direction in Full-Bridge
PWM modes
When
changing
direction,
the
active
and
modulated outputs will improperly go active at the
same time and the dead time does not occur,
which can lead to large shoot-through currents.
Work around
None.
Affected Silicon Revisions
Note:
This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (A8).
