Silicon Errata Issues
1. Module: Data EE Memory
1.1 Data EE Memory Endurance
1.2 Data EE Write at Min. V
2. Module: Program Flash Memory (PFM)
2.1 Program Flash Memory Endurance
 2010 Microchip Technology Inc.
Note:
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
The minimum voltage required for a Data EE write
operation is 2.0 volts.
Work around
None.

2.2 Program Flash Memory writes at Min. V
3. Module: Capture Compare PWM (CCP)
3.1 Dead Band Delay
3.2 ECCP2 Switching Between Single, Half-
3.3 ECCP2 Changing Direction in Full-Bridge
The minimum voltage required for a PFM write
operation is 2.0V.
Work around
None.
Affected Silicon Revisions
With the ECCP configured for PWM half-bridge
mode and a dead-band delay greater than or equal
to the PWM duty cycle; unpredictable wave forms
will result.
Work around
Make sure the dead-band delay is always less
than the PWM duty cycle.
Affected Silicon Revisions
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
PWM modes
When
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.
