The PIC16F87/88 Rev. B1 parts you have received
conform functionally to the Device Data Sheet
(DS30487C), except for the anomalies described
below.
All of the issues listed here will be addressed in future
revisions of the PIC16F87/88 silicon.
The following silicon errata apply only to PIC16F87/88
devices with these Device/Revision IDs:

A high Sleep current will exist when the following
condition is met and procedures are followed:
CONDITION: FOSC<2:0> (Configuration Word 1
Register) bits are configured for any oscillator
selection other than the internal RC oscillator.
PROCEDURE: 
1. Clock switch occurs anywhere in the applica-

tion code where the internal RC oscillator is
selected via the SCS bits (‘10’).

2. Sleep mode is entered while the SCS bits are

configured for the internal RC oscillator (‘10’).

Work around
Before Sleep mode is entered, configure or clear
the SCS bits (‘00’) to switch back to the primary
clock source that is defined by FOSC<2:0>
(Configuration Word 1 Register).

Date Codes that pertain to this issue:
All date codes associated with silicon revision B1.
This issue is not found in devices with silicon
revision C2 (Revision ID 01000) or later.
