Other Special Features
Memory Endurance: The Enhanced Flash cells
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.
Self-Programmability: These devices can write
to their own program memory spaces under inter-
nal 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.
Extended Instruction Set: The
PIC18F2480/2580/4480/4580 family introduces
an optional extension to the PIC18 instruction set,
which adds 8 new instructions and an Indexed
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.
Enhanced CCP Module: In PWM mode, this
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.
Enhanced Addressable USART: This serial
communication module is capable of standard
RS-232 operation and provides support for the
LIN/J2602 bus protocol. 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).
10-Bit A/D Converter: This module incorporates
programmable acquisition time, allowing for a
channel to be selected and a conversion to be
initiated without waiting for a sampling period and
thus, reduce code overhead.
Extended Watchdog Timer (WDT): This
enhanced version incorporates a 16-bit prescaler,
allowing a time-out range from 4 ms to over
131 seconds, that is stable across operating
voltage and temperature.

Details on Individual Family
Members
Devices in the PIC18F2480/2580/4480/4580 family are
available in 28-pin (PIC18F2X80) and 40/44-pin
(PIC18F4X80) 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.
Flash
program
memory
(16 Kbytes
for
PIC18FX480
devices;
32 Kbytes
for
PIC18FX580 devices).
2.
A/D channels (8 for PIC18F2X80 devices; 11 for
PIC18F4X80 devices).
3.
I/O ports (3 bidirectional ports and 1 input only
port on PIC18F2X80 devices; 5 bidirectional
ports on PIC18F4X80 devices).
4.
CCP and Enhanced CCP implementation
(PIC18F2X80 devices have 1 standard CCP
module;
PIC18F4X80
devices
have
one
standard CCP module and one ECCP module).
5.
Parallel
Slave
Port
(present
only
on
PIC18F4X80 devices).
6.
PIC18F4X80 devices provide two comparators.
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
PIC18F2480/2580/4480/4580 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 PIC18F2580),
accommodate an operating VDD range of 4.2V to 5.5V.
Low-voltage parts, designated by “LF” (such as
PIC18LF2580), function over an extended VDD range
of 2.0V to 5.5V.
