The PIC16F505 parts you have received conform
functionally to the Device Data Sheet (DS41236D),
except for the anomalies described below.
Microchip intends to address all issues listed here in
future revisions of the PIC16F505 silicon or develop-
ment tools software. Where noted, issues apply to
listed revision only.
1. Module: MPLAB
© 2007 Microchip Technology Inc.
MPLAB IDE 6.61 does not look for or set the
Configuration Word in the hex file at the
conventional logical location of 0xFFF.
Work around:
The CONFIG data must be assigned in two
locations within the assembly code to ensure
proper Configuration Word placement in the hex
file. This is only required for MPLAB IDE version
6.61 and earlier.

When using the ICD to debug software with the
PIC16F505, bits 5 and 6 in the FSR register must
be cleared to ‘0’. The power-up defaults are 1’s
which causes the device to attempt to access bank
3. This bank is not available on the PIC16F505
devices so the results are invalid.
The power-up defaults are correct on the non-ICD
version of the PIC16F505.
Work around:
Add the following two lines of code early in your
initialization.
This will have no affect on a non-ICD device, but
will correct the initialization errata on ICD devices.
On the PIC16F505 silicon, revisions earlier than
A3, the power-down base current may remain
higher than the specification for a short time when
entering Sleep.
Figure 1 illustrates the device current upon
entering Sleep.
The length of time between the device entering
Sleep mode and the device current reaching I
increases as both temperature and voltage
decrease.
Work around
This issue is fixed in Revisions A3 and later.
