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.
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.
2685/4682/4685 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 con-
figuration 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. Other enhancements include
Auto-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, reduce code overhead.
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.
Other Special Features
1.3
Devices in the PIC18F2682/2685/4682/4685 family are
available in 28-pin (PIC18F2682/2685) and 40/44-pin
(PIC18F4682/4685) 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.
6.
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
PIC18F2682/2685/4682/4685 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 PIC18F2685),
accommodate an operating V
Low-voltage parts, designated by “LF” (such as
PIC18LF2685), function over an extended V
of 2.0V to 5.5V.
Flash program memory (80 Kbytes for
PIC18F2682/4682 devices, 96 Kbytes for
PIC18F2685/4685 devices).
A/D channels (8 for PIC18F2682/2685 devices,
11 for PIC18F4682/4685 devices).
I/O ports (3 bidirectional ports and 1 input only
port
5 bidirectional
devices).
CCP1 and Enhanced CCP1 implementation
(PIC18F2682/2685 devices have 1 standard
CCP1 module, PIC18F4682/4685 devices have
one standard CCP1 module and one ECCP1
module).
