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.
Microchip received ISO/TS-16949:2002 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
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@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)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.

PIC18F8723 FAMILY
1.0
DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
The PIC18F8723 family of devices offers the
advantages of all PIC18 microcontrollers – namely, high
computational performance at an economical price –
with the addition of high-endurance, Enhanced Flash
program memory. In addition to these features, the
PIC18F8723 introduces design enhancements that
make these microcontrollers a logical choice for many
high-performance, power-sensitive applications.
1.1
Special Features
• 12-Bit A/D Converter: The PIC18F8723 family
implements a 12-bit A/D Converter. A/D Converters
in both families incorporate programmable acquisi-
tion time. This allows for a channel to be selected
and a conversion to be initiated, without waiting for
a sampling period and thus, reducing code
overhead.
1.2
Details on Individual Family
Members
Devices in the PIC18F8723 family are available in
64-pin and 80-pin packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2.
The devices are differentiated from each other in the
following ways:
• Flash program memory (96 Kbytes for
PIC18FX628 devices and 128 Kbytes for
PIC18FX723).
• A/D channels (12 for PIC18F6628/6723 devices
and 16 for PIC18F8628/8723 devices).
• I/O ports (seven bidirectional ports on
PIC18F6628/6723 devices and nine bidirectional
ports on PIC18F8628/8723 devices).
• External Memory Bus, configurable for 8 and
16-bit operation
All other features for devices in this family are identical.
These are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2 and
Table 1-3.
Like all Microchip PIC18 devices, members of the
PIC18F8723 family are available as both standard and
low-voltage devices. Standard devices with Enhanced
Flash memory, designated with an “F” in the part
number (such as PIC18F6628), accommodate an
operating V
DD
range of 4.2V to 5.5V. Low-voltage
parts, designated by “LF” (such as PIC18LF6628),
function over an extended V
DD
range of 2.0V to 5.5V.

Note: This data sheet documents only the devices’
features and specifications that are in addition
to the features and specifications of the
PIC18F8722 family devices. For information
on the features and specifications shared by
the PIC18F8723 family and PIC18F8722 fam-
ily devices, see the “PIC18F8722 Family Data
