Note 1:
If you change from this device to another device, please verify oscillator characteristics in your application.
2:
For ROM parts, operation from 2.5V - 3.0V will require the PIC16LCR62X parts.
3:
For OTP parts, operation from 2.5V - 3.0V will require the PIC16LC62X parts.
4:
For OTP parts, operations from 2.7V - 3.0V will require the PIC16LC62XA parts.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Micro-
chip products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined
and enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at
docerrors@mail.microchip.com
or fax the
Reader Response Form
in the back of this data sheet to (480) 792-4150.
We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
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 document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. 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: (480) 792-7277
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.
