The on-chip voltage regulator enable/disable pin
(ENVREG or DISVREG, depending on the device
family) must always be connected directly to either a
supply voltage or to ground. The particular connection
is determined by whether or not the regulator is to be
used:
• For ENVREG, tie to V
• For DISVREG, tie to ground to enable the
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.
The placement of this capacitor should be close to

additional information.
When the regulator is disabled, the V
must be tied to a voltage supply at the V

The PGECx and PGEDx 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
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communi-
cations 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
For device emulation, ensure that the “Communication
Channel
programmed into the device matches the physical
connections for the ICSP to the MPLAB
MPLAB ICD 3 or REAL ICE™ emulator.

REAL ICE emulator connection requirements, refer to
