Silicon Errata Issues
1. Module: Device Reset
2. Module: Device Reset
3. Module: Device Reset
DS80440D-page 6
Note:
A Reset (MCLR) Pulse that is shorter than
2 SYSCLK will not reset the device properly.
Work around
Ensure that the device is held in Reset for more
than 2 SYSCLK to ensure proper device Reset
operation.
Affected Silicon Revisions
All Resets, except Power-on Reset, can cause a
Fail-Safe Clock Monitor event (if enabled) when
the duration of the Reset pulse exceeds the clock
period of the internal fail-safe clock reference clock
(31 kHz).
Work around
If long Reset pulses are anticipated, ignore or
disable Fail-Safe Clock Monitor events.
Affected Silicon Revisions
Attempting to perform a software device Reset
with PBDIV set to 1:1, and SYSCLK less than
1 MHz will not reset the device properly.
Work arounds
Work around 1:
Change PBDIV before performing a software
Reset.
Work around 2:
Set SYSCLK to a value that is greater than 1 MHz.

4. Module: External Voltage Regulator

6. Module: Bus Matrix
A V
CPU to reset when using an external core voltage
supply.
Work arounds
Work around 1:
Use the internal voltage regulator.
Work around 2:
Use an external 1.8V regulator, which has a
regulation specification of ≤ 2.5%. The Microchip
TC1055-1.8VCT713
regulator, or an equivalent, is recommended.
Affected Silicon Revisions
When running the Analog-to-Digital Converter
(ADC) module in Internal Reference mode, the
gain error is 3-4 LSb and the offset error is 1-2 LSb
across voltage and speed.
Work around
Use in-system calibration and software techniques
to compensate for these errors.
Affected Silicon Revisions
The BMXDUDBA, BMXDUPBA and BMXPUPBA
registers can be set to values that are outside the
device’s actual memory size limit.
Work around
Do not write values greater than the specified
memory size of the device to the Bus Matrix
registers. Ensure that the upper bits of the
registers remain clear (‘0’).
