The PIC16F87XA Rev. B6 parts you have received
conform functionally to the Device Data Sheet
(DS39582B), except for the anomalies described
below.
All the issues listed here will be addressed in future
revisions of the PIC16F87XA silicon.

The ADC is disabled when ADCON1<3:0> = 011x
(all inputs digital) and CMCON<2:0> = 111
(comparators are off). This is a special case that
conflicts with the second sentence of Note 1 on
page 131 of the device data sheet: “Pins
configured as digital inputs will convert an analog
input.”
Work around
For the ADC module to be enabled, it is necessary
to either:
1. Enable the comparators (CMCON<2:0> ≠ 111);
2. Configure at least one ADC channel as an
following
analog input (ADCON1<3:0> ≠ 011x).

A very small number of applications are
experiencing a low failure rate when using self-
write through code types of applications. The most
common of these are bootloader operations. This
type of failure is characterized by a few bytes in
program memory not being written as expected. If
this failure is going to occur, it will occur during a
self-write operation. If a failure is not immediately
observed, then there will be no data retention
issues. The failure does not occur when using an
external programmer through In-Circuit Serial
Programming™ (ICSP™).
This failure is dependent on the sequence of
instructions executed after self-writes. Most of the
failures observed have occurred in applications
running at 5V and with an operating frequency of
12 MHz to 17 MHz.
Good power supply decoupling minimizes this
issue. It is recommended that you use a 0.1 μF
decoupling capacitor with each power pin pair. The
decoupling capacitor should be placed very close
to power pins.
It is recommended that you perform statistically
significant testing within your application’s operat-
ing range (i.e., temperature and voltage) with
devices from multiple lots.
Work around
If your devices are exhibiting this type of failure,
please
representative.
