PIC18F66K80 FAMILY
1.1.5 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 28-pin,
40-pin, 44-pin and 64-pin members, or even jumping
from smaller to larger memory devices.
The PIC18F66K80 family is also largely pin compatible
with other PIC18 families, such as the PIC18F4580,
PIC18F4680 and PIC18F8680 families of microcon-
trollers with an ECAN module. This allows a new
dimension to the evolution of applications, allowing
developers to select different price points within
Microchip’s PIC18 portfolio, while maintaining a similar
feature set.
1.2 Other Special Features
• Communications: The PIC18F66K80 family incor-
porates a range of serial communication peripherals,
including two Enhanced USARTs that support
LIN/J2602, one Master SSP module capable of both
SPI and I²C™ (Master and Slave) modes of
operation and an Enhanced CAN module.
• CCP Modules: PIC18F66K80 family devices
incorporate four Capture/Compare/PWM (CCP)
modules. Up to four different time bases can be
used to perform several different operations at
once.
• ECCP Modules: The PIC18F66K80 family has
one Enhanced CCP (ECCP) module to maximize
flexibility in control applications:
- Up to four different time bases for performing
several different operations at once
- Up to four PWM outputs
- Other beneficial features, such as polarity
selection, programmable dead time,
auto-shutdown and restart, and Half-Bridge
and Full-Bridge Output modes
• 12-Bit A/D Converter: The PIC18F66K80 family
has a differential A/D. It 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, reducing code overhead.
• Charge Time Measurement Unit (CTMU): The
CTMU is a flexible analog module that provides
accurate differential time measurement between
pulse sources, as well as asynchronous pulse
generation.
Together with other on-chip analog modules, the
CTMU can precisely measure time, measure
capacitance or relative changes in capacitance, or
generate output pulses that are independent of the
system clock.
• LP Watchdog Timer (WDT): This enhanced
version incorporates a 22-bit prescaler, allowing
an extended time-out range that is stable across
operating voltage and temperature. See
Section 31.0 “Electrical Characteristics” for
time-out periods.
1.3 Details on Individual Family
Members
Devices in the PIC18F66K80 family are available in
28-pin, 40/44-pin and 64-pin packages. Block diagrams
for each package are shown in Figure 1-1, Figure 1-2
and Figure 1-3, respectively.
The devices are differentiated from each other in these
ways:
• Flash Program Memory:
- PIC18FX5K80 (PIC18F25K80, PIC18F45K80
and PIC18F45K80) – 32 Kbytes
- PIC18FX6K80 (PIC18F26K80, PIC18F46K80
and PIC18F66K80) – 64 Kbytes
• I/O Ports:
- PIC18F2XK80 (28-pin devices) –
Three bidirectional ports
- PIC18F4XK80 (40/44-pin devices) –
Five bidirectional ports
- PIC18F6XK80 (64-pin devices) –
Seven bidirectional ports
All other features for devices in this family are identical.
These are summarized in Table 1-1, Table 1-2 and
Table 1-3.
The pinouts for all devices are listed in Table 1-4,
Table 1-5 and Table 1-6.
