DEVICE OVERVIEW
This document contains device specific information for
the following devices:
This family offers the same advantages of all PIC18
microcontrollers
–
namely,
high
computational
performance at an economical price – with the addition of
high endurance Enhanced Flash program memory. The
PIC18FXX20 family also provides an enhanced range of
program memory options and versatile analog features
that make it ideal for complex, high-performance
applications.
1.1
Key Features
1.1.1
EXPANDED MEMORY
The PIC18FXX20 family introduces the widest range of
on-chip, Enhanced Flash program memory available
on PICmicro microcontrollers – up to 128 Kbyte (or
65,536 words), the largest ever offered by Microchip.
For users with more modest code requirements, the
family also includes members with 32 Kbyte or
64 Kbyte.
Other memory features are:
Data RAM and Data EEPROM: The
PIC18FXX20 family also provides plenty of room
for application data. Depending on the device,
either 2048 or 3840 bytes of data RAM are
available. All devices have 1024 bytes of data
EEPROM for long-term retention of nonvolatile
data.
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.
1.1.2
EXTERNAL MEMORY INTERFACE
In the event that 128 Kbytes of program memory is
inadequate for
an application,
the PIC18F8X20
members of the family also implement an External
Memory Interface. This allows the controller’s internal
program counter to address a memory space of up to
2 Mbytes, permitting a level of data access that few
8-bit devices can claim.
With the addition of new operating modes, the External
Memory Interface offers many new options, including:
Operating the microcontroller entirely from external
memory
Using
combinations
of
on-chip
and
external
memory, up to the 2-Mbyte limit
Using external Flash memory for reprogrammable
application code, or large data tables
Using external RAM devices for storing large
amounts of variable data
1.1.3
EASY MIGRATION
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. This is true when moving between the 64-pin
members, between the 80-pin members, or even
jumping from 64-pin to 80-pin devices.
1.1.4
OTHER SPECIAL FEATURES
Communications: The PIC18FXX20 family
incorporates a range of serial communications
peripherals, including 2 independent USARTs and
a Master SSP module, capable of both SPI and
I2C (Master and Slave) modes of operation. For
PIC18F8X20 devices, one of the general purpose
I/O ports can be reconfigured as an 8-bit Parallel
Slave Port for direct processor-to-processor
communications.
CCP Modules: All devices in the family
incorporate five Capture/Compare/PWM modules
to maximize flexibility in control applications. Up
to four different time bases may be used to
perform several different operations at once.
Analog Features: All devices in the family
feature 10-bit A/D converters, with up to 16 input
channels, as well as the ability to perform
conversions during Sleep mode. Also included
are dual analog comparators with programmable
input and output configuration, a programmable
Low-Voltage Detect module and a programmable
Brown-out Reset module.
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.
