Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS39933D).
1. Module: Guidelines for Getting Started
Section 2.4 “Voltage Regulator Pins (ENVREG and
V
more detailed section. The entire text follows:
2.4
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
regulator, while tying it to ground disables the regulator.
Refer to Section 25.3 “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
V
use a capacitor of 10 µF connected to ground. The
capacitor type can be ceramic or tantalum. Suitable
examples of capacitors are shown in

It is recommended that the trace length not exceed
0.25 inch (6 mm). Refer to Section 28.0 “Electrical
Characteristics” for additional information.
When the regulator is disabled, the V
must be tied to a voltage supply at the 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
