1.0
This document contains device-specific information for
the following devices:
• PIC18F86J72
• PIC18F87J72
This family combines the traditional advantages of all
PIC18 microcontrollers – namely, high computational
performance and a rich feature set – with a versatile
on-chip
high-accuracy analog front end. These features make
the PIC18F87J72 family a logical choice for many
high-performance power and metering applications
where price is a primary consideration.

1.1.1
All of the devices in the PIC18F87J72 family incorporate
a range of features that can significantly reduce power
consumption during operation. Key items include:
• Alternate Run Modes: By clocking the controller
• Multiple Idle Modes: The controller can also run
• On-the-Fly Mode Switching: The power-managed
1.1.2
All of the devices in the PIC18F87J72 family offer six
different oscillator options, allowing users a range of
choices in developing application hardware. These
include:
• Two Crystal modes using crystals or ceramic
• Two External Clock modes offering the option of a

PIC18F87J72 FAMILY
The internal oscillator block provides a stable reference
source that gives the family additional features for
robust operation:
• Fail-Safe Clock Monitor: This option constantly
• Two-Speed Start-up: This option allows the
1.1.3
The PIC18F87J72 family provides ample room for
application code with 128 Kbytes of code space. The
Flash cells for program memory are rated to last up to
10,000 erase/write cycles. Data retention without
refresh is conservatively estimated to be greater than
20 years.
The Flash program memory is readable and writable.
During normal operation, the PIC18F87J72 family also
provides plenty of room for dynamic application data
with up to 3,923 bytes of data RAM.
1.1.4
The PIC18F87J72 family implements the optional
extension to the PIC18 instruction set, adding 8 new
instructions and an Indexed Addressing mode.
Enabled as a device configuration option, the extension
has been specifically designed to optimize re-entrant
application code originally developed in high-level
languages, such as ‘C’.
1.1.5
Regardless of the memory size, all devices share the
same rich set of peripherals, allowing for a smooth
migration path as applications grow and evolve.
The consistent pinout scheme used throughout the
entire family also aids in migrating to the next larger
device.
The PIC18F87J72 family is also largely pin compatible
with other PIC18 families, such as the PIC18F8720 and
PIC18F8722, the PIC18F85J11, and the PIC18F8490
and PIC18F85J90 families of microcontrollers with
LCD drivers. This allows a new dimension to the
evolution of applications, allowing developers to select
different price points within Microchip’s PIC18 portfolio,
while maintaining a similar feature set.
