The on-chip voltage regulator enable pin, ENVREG,
must always be connected directly to either a supply
voltage or to ground. Tying ENVREG to V
the regulator, while tying it to ground disables the
regulator. Refer to Section 24.3 “On-Chip Voltage
Regulator” for details on connecting and using the
on-chip regulator.
When the regulator is enabled, a low-ESR (<5Ω)
capacitor is required on the V
stabilize the voltage regulator output voltage. The
V
must use a capacitor of 10 μF connected to ground. The
type can be ceramic or tantalum. A suitable example is
the Murata GRM21BF50J106ZE01 (10 μF, 6.3V) or
equivalent. Designers may use Figure 2-3 to evaluate
ESR equivalence of candidate devices.
It is recommended that the trace length not exceed
0.25 inch (6 mm). Refer to Section 27.0 “Electrical
Characteristics” for additional information.
When the regulator is disabled, the V
must be tied to a voltage supply at the V
Refer to Section 27.0 “Electrical Characteristics” for
information on V
Note that the “LF” versions of some low pin count
PIC18FJ parts (e.g., the PIC18LF45J10) do not have
the ENVREG pin. These devices are provided with the
voltage regulator permanently disabled; they must
always be provided with a supply voltage on the
V

The PGC and PGD pins are used for In-Circuit Serial
Programming (ICSP) and debugging purposes. It is
recommended to keep the trace length between the
ICSP connector and the ICSP pins on the device as
short as possible. If the ICSP connector is expected to
experience an ESD event, a series resistor is recom-
mended, with the value in the range of a few tens of
ohms, not to exceed 100Ω.
Pull-up resistors, series diodes and capacitors on the
PGC and PGD pins are not recommended as they will
interfere
munications to the device. If such discrete components
are an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective device
Flash programming specification for information on
capacitive loading limits and pin input voltage high (V
and input low (V
For device emulation, ensure that the “Communication
Channel Select” (i.e., PGC/PGD pins) programmed
into the device matches the physical connections for
the ICSP to the MPLAB
REAL ICE™ emulator.

emulator connection requirements, refer to the following
