rfPIC12F675K/675F/675H
The rfPIC12F675K/675F/675H parts you have
received conform functionally to the Device Data Sheet
(DS70091A), except for the anomalies described
below.
All the problems listed here will be addressed in future
revisions of the rfPIC12F675K/675F/675H silicon.
1. Module: VDD and VDDRF Supply Voltage
VDD and VDDRF Supply Voltage maximum has
been reduced to 4.5V.
Work around
Reduce VDD and VDDRF Supply Voltage to less
than or equal to 4.5V.
Date Codes that pertain to this issue:
All engineering and production devices beginning
with date code 0340XXX.
2. Module: Loop Filter (LF) Pin 13 changed
to no connection
The loo p filter (LF) sig nal wil l no longer be bo nde d
out. Pin 13 is a no connec tion.
Work around
Remove all circuitry to the LF pin.
Date Codes that pertain to this issue:
All engineering and production devices beginning
with date code 0340XXX.
3. Module: Reference Clock (REFCLK) Pin 7
changed to no connection
The reference clock (REFCLK) signal will no
longer be bonded out. Pin 7 is a no connection.
Work around
Remove all circuitry to the REFCLK pin.
Date Codes that pertain to this issue:
All engineering and production devices beginning
with date code 0340XXX.
Clarifications/Correc ti ons to the Data
Sheet:
In the Device Data Sheet (DS70091A), the following
clarifications and corrections should be noted.
1. Module: Loop Filter (LF) Pin 13 changed
to no connection
LF pin 13 has been changed to no connection
(NC). All references in the data sheet referring to
the LF pin should be deleted.
• Pin Diagram pa ge 1: repla ce LF with NC (no
connection).
• Figure 1-1: remove LF pin connection.
• Table 1-1: replace LF with NC (no connection).
• Figure 9-1: remove LF pin connection.
• Figure 9-5: replace LF with NC (no connection)
• Figure 9-6: replace LF with NC (no connection)
• Section 9.7: delete section.
2. Module: Reference Clock (REFCLK) Pin 7
changed to no connection
REFCLK pin 7 has been changed to no connection
(NC). All references in the data sheet referring to
the REFCLK pin should be deleted.
• Pin Diagram pa ge 1: repla ce REFCLK with NC
(no connection).
• Figure 1-1: remove Clock Divider block and
REFCLK pin connection.
• Table 1-1: replace REFCLK with NC (no
connection).
• Figure 9-1: remove Clock Divider block and
REFCLK pin connection.
• Figure 9-5: replace REFCLK with NC (no
connection)
• Figure 9-6: replace REFCLK with NC (no
connection)
• Section 9.6: delete section.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code prot ection features of our
products. Attempts to break microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such a c t s
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received QS-9000 quality system
certification for its worldwide headquarters,
