This document contains device-specific information for
the following devices:
This family of devices offers the advantages of all
PIC18 microcontrollers – namely, high computational
performance at an economical price – with the addition
of
memory.
PIC18F2455/2550/4455/4550 family introduces design
enhancements that make these microcontrollers a log-
ical choice for many high-performance, power sensitive
applications.

1.1.1
All of the devices in the PIC18F2455/2550/4455/4550
family incorporate a range of features that can signifi-
cantly reduce power consumption during operation.
Key items include:
• Alternate Run Modes: By clocking the controller
• Multiple Idle Modes: The controller can also run
• On-the-Fly Mode Switching: The
• Low Consumption in Key Modules: The power
1.1.2
Devices in the PIC18F2455/2550/4455/4550 family
incorporate a fully featured Universal Serial Bus
communications module that is compliant with the USB
Specification Revision 2.0. The module supports both
low-speed and full-speed communication for all sup-
ported data transfer types. It also incorporates its own
on-chip transceiver and 3.3V regulator and supports
the use of external transceivers and voltage regulators.

reduced even further, to as little as 4%, of normal
operation requirements.

All of the devices in the PIC18F2455/2550/4455/4550
family offer twelve different oscillator options, allowing
users a wide range of choices in developing application
hardware. These include:
