You can determine the version of a data sheet by examining its literature number found on the bottom outside corner
of any page. The last character of the literature number is the version number. e.g., DS30000A is version A of doc-
ument DS30000.
Errata
An errata sheet may exist for current devices, describing minor operational differences (from the data sheet) and rec-
ommended workarounds. As device/documentation issues become known to us, we will publish an errata sheet. The
errata will specify the revision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
• The Microchip Corporate Literature Center; U.S. FAX: (602) 786-7277
When contacting a sales office or the literature center, please specify which device, revision of silicon and data sheet
(include literature number) you are using.
