25.3
The digital core logic of the PIC18F46J11 family
devices is designed on an advanced manufacturing
process, which requires 2.0V to 2.7V. The digital core
logic obtains power from the V
supply pin.
However, in many applications it may be inconvenient
to run the I/O pins at the same core logic voltage, as it
would restrict the ability of the device to interface with
other, higher voltage devices, such as those run at a
nominal 3.3V. Therefore, all PIC18F46J11 family
devices implement a dual power supply rail topology.
The core logic obtains power from the V
pin, while the general purpose I/O pins obtain power
from the V
supplied with a voltage between 2.15V to 3.6V (“F”
devices) or 2.0V to 3.6V (“LF” devices).
This dual supply topology allows the microcontroller to
interface with standard 3.3V logic devices, while
running the core logic at a lower voltage of nominally
2.5V.
In order to make the microcontroller more convenient to
use, an integrated 2.5V low dropout, low quiescent
current linear regulator has been integrated on the die
inside PIC18F46J11 family devices. This regulator is
designed specifically to supply the core logic of the
device. It allows PIC18F46J11 family devices to
effectively run from a single power supply rail, without
the need for external regulators.
The on-chip voltage regulator is always enabled on “F”
devices. The V

On “LF” devices, the on-chip regulator is always
disabled. This allows the device to save a small amount
of quiescent current consumption, which may be
advantageous in some types of applications, such as
those which will entirely be running at a nominal 2.5V.
On PIC18LF46J11 family devices, the V
pin still serves as the core logic power supply input pin,
and therefore, must be connected to a 2.0V to 2.7V
supply rail at the application circuit board level. On
these devices, the I/O pins may still optionally be sup-
plied with a voltage between 2.0V to 3.6V, provided that

When it is enabled, the on-chip regulator provides a con-
stant voltage of 2.5V nominal to the digital core logic.

Tracking mode, the regulator output follows V
typical voltage drop of 100 mV or less.
The on-chip regulator includes a simple, Low-Voltage
Detect (LVD) circuit. This circuit is separate and inde-
pendent of the High/Low-Voltage Detect (HLVD) module
described in Section 23.0 “High/Low Voltage Detect
(HLVD)”. The on-chip regulator LVD circuit continuously
monitors the V
LVDSTAT bit in the WDTCON register. The LVD detect
threshold is set slightly below the normal regulation set
point of the on-chip regulator.
Application firmware may optionally poll the LVDSTAT
bit to determine when it is safe to run at the maximum
rated frequency, so as not to inadvertently violate the
voltage versus frequency requirements provided by
Figure 28-1.
