PIC18F87J10 FAMILY
A.1
The
PIC18F87J10 and PIC18F8722 device families is the
power
designed on a smaller process; this results in lower
maximum voltage and higher leakage current.
The operating voltage range for PIC18F87J10 devices
is 2.0V to 3.6V. In addition, these devices have split
power requirements: one for the core logic and one for
the I/O. One of the V

Section 27.0 “Electrical Characteristics”.
A.2
There are several differences in the pinouts between
the PIC18F87J10 and the PIC18F8722 families:
• Input voltage tolerance
• Output current capabilities
• Available I/O
Pins on the PIC18F87J10 that have digital only input
capability will tolerate voltages up to 5.5V and are thus
tolerant to voltages above V
Section 11.0 “I/O Ports” contains the complete list.
In addition to input differences, there are output differ-
ences as well. PIC18F87J10 devices have three
classes of pin output current capability: high, medium
and low. Not all I/O pins can source or sink equal levels
of current. Only PORTB and PORTC support the
25 mA source/sink capability that is supported by all
output pins on the PIC18F8722. Table 11-2 in
Section 11.0 “I/O Ports” contains the complete list of
output capabilities.
There are additional differences in how some pin func-
tions are implemented on PIC18F87J10 devices. First,
the OSC1/OSC2 oscillator pins are strictly dedicated to
the external oscillator function; there is no option to
re-allocate these pins to I/O (RA6 or RA7) as on
PIC18F8722 devices. Second, the MCLR pin is
dedicated only to MCLR and cannot be configured as
an input (RG5). Finally, RF0 does not exist on
PIC18F87J10 devices.
All of these pin differences (including power pin
differences) should be accounted for when making a
conversion between PIC18F8722 and PIC18F87J10
devices.

A.3
PIC18F8722 devices have a greater range of oscillator
options than PIC18F87J10 devices. The latter family is
limited primarily to operating modes that support HS
and EC oscillators.
In addition, the PIC18F87J10 has an internal RC
oscillator with only a fixed 32 kHz output. The higher
frequency RC modes of the PIC18F8722 family are not
available.
Both device families have an internal PLL. For the
PIC18F87J10 family, however, the PLL must be
enabled in software.
The clocking differences should be considered when
making a conversion between the PIC18F8722 and
PIC18F87J10 device families.

Peripherals must also be considered when making a
conversion between the PIC18F87J10 and the
PIC18F8722 families:
