to their own program memory spaces under
internal software control. By using a bootloader
routine, located in the protected Boot Block at the
top of program memory, it becomes possible to
create an application that can update itself in the
field.
4450 family introduces an optional extension to
the PIC18 instruction set, which adds 8 new
instructions and an Indexed Literal Offset
Addressing mode. This extension, enabled as a
device configuration option, has been specifically
designed to optimize re-entrant application code

as C.

RS-232 operation and provides support for the LIN
bus protocol. Other enhancements include
Automatic Baud Rate Detection and a 16-bit Baud
Rate Generator for improved resolution.

channel to be selected and a conversion to be
initiated, without waiting for a sampling period and
thus, reducing code overhead.
introduce the use of debugger and programming
pins that are not multiplexed with other micro-
controller features. Offered as an option in select
packages, this feature allows users to develop I/O
intensive applications while retaining the ability to
program and debug in the circuit.
Other Special Features
Preliminary
1.3
Devices in the PIC18F2450/4450 family are available
in 28-pin and 40/44-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 the
following two ways:
1.
2.
All other features for devices in this family are identical.
These are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2 and
Table 1-3.
Like all Microchip PIC18 devices, members of the
PIC18F2450/4450 family are available as both standard
and low-voltage devices. Standard devices with
Enhanced Flash memory, designated with an “F” in the
part number (such as PIC18F2450), accommodate an
operating V
designated by “LF” (such as PIC18LF2450), function
over an extended V
A/D channels (10 for 28-pin devices, 13 for
40/44-pin devices).
I/O ports (3 bidirectional ports and 1 input only
port on 28-pin devices, 5 bidirectional ports on
40/44-pin devices).
