PIC18F87K22 FAMILY

1.1.6
EASY MIGRATION
All devices share the same rich set of peripherals
except that the devices with 32 Kbytes of program
memory (PIC18F65K22 and PIC18F85K22) have two
less CCPs and three less timers. This provides a
smooth migration path within the device family as
applications evolve and grow.
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.
All of the devices in the family share the same rich set
of peripherals, except for those with 32 Kbytes of
program memory (PIC18F65K22 and PIC18F85K22).
Those devices have two less CCPs and three less
timers.
The PIC18F87K22 family is also largely pin compatible
with other PIC18 families, such as the PIC18F8720 and
PIC18F8722 and the PIC18F85J11. 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.

Other Special Features
Communications: The PIC18F87K22 family
incorporates a range of serial communication
peripherals, including two Enhanced USARTs
(EUSART) that support LIN/J2602, and two
Master SSP modules, capable of both SPI and
I2C (Master and Slave) modes of operation.
CCP Modules: PIC18F87K22 family devices
incorporate up to seven Capture/Compare/PWM
(CCP) modules. Up to six different time bases can
be used to perform several different operations at
once.
ECCP Modules: The PIC18F87K22 family has
three Enhanced CCP (ECCP) modules to
maximize flexibility in control applications:
- Up to eight different time bases for
performing several different operations
at once
- Up to four PWM outputs for each module, for
a total of 12 PWMs
- 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 PIC18F87K22 family
has differential ADC. It incorporates program-
mable 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
for
time-out periods.
Real-Time Clock and Calendar Module
(RTCC):
The RTCC module is intended for appli-
cations requiring that accurate time be maintained
for extended periods of time with minimum to no
intervention from the CPU.
The module is a 100-year clock and calendar with
automatic leap year detection. The range of the
clock is from 00:00:00 (midnight) on January 1,
2000 to 23:59:59 on December 31, 2099.
