Silicon Errata and Data Sheet Clarification
The SST38VF640XB family devices that you have
received conform functionally to the current Device
Data Sheet (DS20005002D), except for the anomalies
described in this document.
The silicon issues discussed in the following pages are
for silicon revisions with the Device and Revision IDs
listed in
Table 1.
The silicon issues are summarized in
Table 2.
Note:
This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the issues
indicated in the last column of
Table 2
apply to the current silicon revision (A).
Data Sheet clarifications and corrections start on
Page 3,
following the discussion of silicon issues.

Silicon Errata Issues
Note:
This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (A).
Work around
Prior to issuing a Security ID Entry command,
hardware reset using /RST pin must be
performed. A software reset (Addr=XXH,
Data=F0H) instead of a hardware reset does not
work in this condition.

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
