PIC18F6527/6622/8527/8622
The PIC18F6527/6622/8527/8622 parts you have
received conform functionally to the Device Data Sheet
(DS39646B), except for the anomalies described
below. Any Data Sheet Clarification issues related to
the PIC18F6527/6622/8527/8622 devices will be
reported in a separate Data Sheet errata. Please check
the Microchip web site for any existing issues.
All of the issues listed here will be addressed in future
revisions of the PIC18F6527/6622/8527/8622 silicon.
The
following
silicon
errata
apply
only
to
PIC18F6527/6622/8527/8622 devices with these
Device/Revision IDs:
1.
Module: A/D
The A/D offset is greater than the specified limit in
Table 28-26 of the Device Data Sheet. The
updated conditions and limits are shown in bold
text in Table 1.
Work around
Three work arounds exist.
1. Configure the A/D to use the VREF+ and VREF-
pins for the voltage references. This is done by
setting the VCFG<1:0> bits (ADCON1<5:4>).
2. Perform a conversion on a known voltage
reference voltage and adjust the A/D result in
software.
3. Increase system clock speed and adjust A/D
settings accordingly. Higher system clock
frequencies decrease offset error.
Date Codes that pertain to this issue:
All engineering and production devices.

2.
Module: EUSART
In Synchronous mode, EUSART baud rates using
SPBRGx values of ‘0’ and ‘1’ may not function
correctly.
Work around
Use another baud rate configuration to generate
the desired baud rate.
3.
Module: EUSART
After the last received byte has been read from the
EUSART receive buffer, RCREGx, the value is no
longer valid for subsequent read operations. The
RCREGx register should only be read once for
each byte received.
Work around
After each byte is received from the EUSART,
store the byte into a user variable. To determine
when a byte is available to read from RCREGx,
poll the RCIDL (BAUDCONx<6>) bit for a low-to-
high transition or use the EUSART Receive
Interrupt Flag, RC1IF (PIR1<5>).
