PIC18F97J60 FAMILY
24.3
All of the PIC18F97J60 family devices power their core
digital logic at a nominal 2.5V. This may create an issue
for designs that are required to operate at a higher
typical voltage, such as 3.3V. To simplify system
design, all devices in the PIC18F97J60 family incor-
porate an on-chip regulator that allows the device to
run its core logic from V
The regulator is controlled by the ENVREG pin. Tying
V
provides power to the core from the other V
When the regulator is enabled, a low-ESR filter capacitor
must be connected to the
(Figure 24-2). This helps to maintain the stability of the
regulator. The recommended value for the filter capacitor
is provided in Section 27.3 “DC Characteristics:
PIC18F97J60 Family (Industrial)”.
If ENVREG is tied to V
this case, separate power for the core logic, at a nomi-
nal 2.5V, must be supplied to the device on the
V
levels, typically 3.3V. Alternatively, the V

nominal voltage. Refer to Figure 24-2 for possible
configurations.
24.3.1
When the on-chip regulator is enabled, PIC18F97J60
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 Brown-out 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
Section 4.4.1 “Detecting BOR”. The Brown-out
Reset voltage levels are specific in Section 27.1 “DC
Characteristics: Supply Voltage”.
24.3.2
The on-chip regulator is designed to meet the power-up
requirements for the device. If the application does not
use the regulator, then strict power-up conditions must
be adhered to. While powering up, V
