This document contains device-specific information for
the following devices:
This family introduces a line of low-voltage, general
purpose microcontrollers with the main traditional
advantage of all PIC18 microcontrollers – namely, high
computational performance and a rich feature set – at
an extremely competitive price point. These features
make the PIC18F87J11 Family a logical choice for

a primary consideration.

1.1.1
All of the devices in the PIC18F87J11 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

All of the devices in the PIC18F87J11 Family offer four
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

1.1.3
The PIC18F87J11 family provides ample room for
application code, from 64 Kbytes to 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, writable, and
during normal operation, the PIC18F87J11 Family also
provides plenty of room for dynamic application data
with up to 3930 bytes of data RAM.
1.1.4
In the event that 128 Kbytes of memory are inadequate
for an application, the 80-pin members of the
PIC18F87J11 Family also implement an External Mem-
ory Bus (EMB). 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
1.1.5
The PIC18F87J11 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

languages, such as ‘C’.
