1.0
This document contains device-specific information for
the following devices:
This family combines the traditional advantages of all
PIC18 microcontrollers – namely, high computational
performance and a rich feature set – while maintaining
an extremely competitive price point. These features
make the PIC18F85J11 family a logical choice for
many high-performance applications where price is a
primary consideration.
1.1
1.1.1
All of the devices in the PIC18F85J11 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 PIC18F85J11 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
• A Phase Lock Loop (PLL) frequency multiplier,
• An internal oscillator block which provides an

PIC18F85J11 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 PIC18F85J11 family provides a range of program
memory options, from 8 Kbytes to 32 Kbytes of code
space. The Flash cells for program memory are rated
to last up to 1000 erase/write cycles. Data retention
without refresh is conservatively estimated to be
greater than 20 years.
The PIC18F85J11 family also provides plenty of room
for dynamic application data, with up to 2048 bytes of
data RAM.
1.1.4
The PIC18F85J11 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
In the event that 32 Kbytes of memory are inadequate
for an application, the 80-pin members of the
PIC18F85J11 family also implement an external mem-
ory bus. This allows the controller’s internal program
counter to address a memory space of up to 2 Mbytes,
permitting a level of data access that few 8-bit devices
can claim. This allows additional memory options,
including:
• Using combinations of on-chip and external
• Using external Flash memory for reprogrammable
• Using external RAM devices for storing large
