20.3
In parts designated “LF”, the microcontroller core is
powered from an external source that is separate from
V
In “F” devices, a low-ESR capacitor must be connected
to the V
In parts designated with an “LF” part number (i.e.,
PIC18LF45J10), power to the core must be supplied on
V
have sufficient capacitance on all supply pins.
Examples are shown in Figure 20-2.
The specifications for core voltage and capacitance
are listed inTable 23-4 of Section 23.0 “Electrical
Characteristics”.

PIC18F45J10 FAMILY
20.3.1
When the on-chip regulator is enabled, PIC18F45J10
family devices also have a simple brown-out capability.
If the voltage supplied to the regulator is inadequate to
maintain a regulated level, the regulator Reset circuitry
will generate a BOR Reset. This event is captured by
the BOR flag bit (RCON<0>).
The operation of the BOR is described in more detail in
Section 4.4
(PIC18F2XJ10/4XJ10
Section 4.4.1 “Detecting BOR”. The brown-out voltage
levels are specific in Section 23.1 “DC Characteristics:
Supply Voltage”.

requirements for the device. While powering up,
