PIC18F45J10 FAMILY
B.1
The
PIC18F45J10 family and PIC18F4520 device families
is the power requirements. PIC18F45J10 family
devices are designed on a smaller process; this results
in lower maximum voltage and higher leakage current.
The operating voltage range for PIC18F45J10 family
devices is 2.0V to 3.6V. One of the V
for the core logic supply (V
voltage and capacitor requirements as described in
Section 23.0 “Electrical Characteristics”.
The current specifications for PIC18F45J10 family
devices are yet to be determined.
B.2
There are several differences in the pinouts between
the PIC18F45J10 family and the PIC18F4520 families:
• Input voltage tolerance
• Output current capabilities
• Available I/O
Pins on the PIC18F45J10 family that have digital only
input capability will tolerate voltages up to 5.5V and are
thus tolerant to voltages above V
Section 9.0 “I/O Ports” contains the complete list.
In addition to input differences, there are output differ-
ences as well. 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 PIC18F4520. Table 9-2 in
Section 9.0 “I/O Ports” contains the complete list of
output capabilities.
There are additional differences in how some pin func-
tions are implemented on PIC18F45J10 family
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 PIC18F4520 devices. Second, the
MCLR pin is dedicated only to MCLR and cannot be
configured as an input (RE3). Finally, RA4 does not
exist on PIC18F45J10 family devices.
All of these pin differences (including power pin
differences) should be accounted for when making a
conversion between PIC18F4520 and PIC18F45J10
family devices.

B.3
PIC18F4520 family devices have a greater range of
oscillator options than PIC18F45J10 family devices.
The latter family is limited primarily to operating modes
that support HS and EC oscillators.
In addition, the PIC18F45J10 family has an internal RC
oscillator with only a fixed 32 kHz output. The higher
frequency RC modes of the PIC18F4520 family are not
available.
B.4
The PIC18F45J10 family is able to operate at 40 MHz
down to 2.15 volts unlike the PIC18F4520 family where
40 MHz operation is limited to 4.2 +V applications.
Peripherals must also be considered when making a
conversion between the PIC18F45J10 family and the
PIC18F4520 families:
• Data EEPROM: PIC18F45J10 family devices do
