PIC18F46J11 FAMILY
1.1.4
The PIC18F46J11 family implements the optional
extension to the PIC18 instruction set, adding eight
new instructions and an Indexed Addressing mode.
Enabled as a device configuration option, the extension
has been specifically designed to optimize re-entrant
application code originally developed in high-level
languages, such as C.
1.1.5
Regardless of the memory size, all devices share the
same rich set of peripherals, allowing for a smooth
migration path as applications grow and evolve.
The consistent pinout scheme used throughout the
entire family also aids in migrating to the next larger
device.
The PIC18F46J11 family is also pin compatible with
other PIC18 families, such as the PIC18F4620,
PIC18F4520 and PIC18F45J10. This allows a new
dimension to the evolution of applications, allowing
developers to select different price points within
Microchip’s PIC18 portfolio, while maintaining the
same feature set.

incorporates a range of serial and parallel
communication peripherals. This device also
includes two independent Enhanced USARTs and
two Master Synchronous Serial Port (MSSP)
modules, capable of both Serial Peripheral Inter-
face (SPI) and I
operation. The device also has a parallel port and
can be configured to serve as either a Parallel
Master Port (PMP) or as a Parallel Slave Port
(PSP).
incorporate three Enhanced
Capture/Compare/PWM (ECCP) modules to
maximize flexibility in control applications. Up to
four different time bases may be used to perform
several different operations at once. Each of the
ECCPs offers up to four PWM outputs, allowing for
a total of eight PWMs. The ECCPs also offer many
beneficial features, including polarity selection, pro-
grammable dead time, auto-shutdown and restart
and Half-Bridge and Full-Bridge Output modes.

Devices in the PIC18F46J11 family are available in
28-pin and 44-pin packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2.
The devices are differentiated from each other in two
ways:
• Flash program memory (three sizes: 16 Kbytes
• I/O ports (three bidirectional ports on 28-pin
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2.
The pinouts for the PIC18F2XJ11 devices are listed in
Table 1-3 and the pinouts for the PIC18F4XJ11 devices
are listed in Table 1-4.
The PIC18F46J11 family of devices provides an
on-chip voltage regulator to supply the correct voltage
levels to the core. Parts designated with an “F” part
number (such as PIC18F46J11) have the voltage
regulator enabled.
These parts can run from 2.15V-3.6V on V

low-ESR capacitor. Parts designated with an “LF” part
number (such as PIC18LF46J11) do not enable the volt-
age regulator. For “LF” parts, an external supply of
2.0V-2.7V has to be supplied to the V

channel to be selected and a conversion to be

thus, reducing code overhead.

allowing an extended time-out range that is stable
across operating voltage and temperature. See
