for both program memory and data EEPROM are
rated to last for many thousands of erase/write
cycles – up to 100,000 for program memory and
1,000,000 for EEPROM. Data retention without
refresh is conservatively estimated to be greater
than 40 years.
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.
PIC18F2455/2550/4455/4550 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 originally developed in high-level
languages such as C.
module provides 1, 2 or 4 modulated outputs for
controlling half-bridge and full-bridge drivers.
Other features include auto-shutdown for
disabling PWM outputs on interrupt or other select
conditions, and auto-restart to reactivate outputs
once the condition has cleared.
communication module is capable of standard
RS-232 operation and provides support for the LIN
bus protocol. The TX/CK and RX/DT signals can
be inverted, eliminating the need for inverting
buffers. Other enhancements include Automatic
Baud Rate Detection and a 16-bit Baud Rate
Generator for improved resolution. When the
microcontroller is using the internal oscillator
block, the EUSART provides stable operation for
applications that talk to the outside world without
using an external crystal (or its accompanying
power requirement).
programmable acquisition time, allowing for a
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
1.3
Devices in the PIC18F2455/2550/4455/4550 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 six
ways:
1.
2.
3.
4.
5.
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
PIC18F2455/2550/4455/4550 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 PIC18F2550),
accommodate an operating V
Low-voltage parts, designated by “LF” (such as
PIC18LF2550), function over an extended V
of 2.0V to 5.5V.

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).
CCP and Enhanced CCP implementation
(28-pin devices have two standard CCP
modules, 40/44-pin devices have one standard
CCP module and one ECCP module).
