PIC10F220/222 Rev. A Silicon Errata
1. Module: Analog-to-Digital (A/D)
Converter
The PIC10F220/222 parts you have received conform
functionally to the Device Data Sheet (DS41270B),
except for the anomalies described below.
PIC10F220/222 silicon Rev. A1. The A/D Converter
does not meet the design target. The specifications
listed below in Table 10-6 supersede Table 10-6 in
DS41270B.
All issues listed here will be addressed in future
revisions of the PIC10F220/222 silicon. Where noted,
problems apply to listed revision only.

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 protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
