PIC18F87J11 FAMILY
1.1.6 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.
The PIC18F87J11 family is also pin compatible with
other PIC18 families, such as the PIC18F87J10,
PIC18F85J11, PIC18F8720 and PIC18F8722. This
allows a new dimension to the evolution of applications,
allowing developers to select different price points
within Microchip’s PIC18 portfolio, while maintaining
the same feature set.
1.2 Other Special Features
• Communications: The PIC18F87J11 family
incorporates a range of serial and parallel com-
munication peripherals. These devices all include
2 independent Enhanced USARTs and 2 Master
SSP modules, capable of both SPI and I²C™
(Master and Slave) modes of operation. The
devices also have a parallel port and can be
configured to function as either a Parallel Master
Port (PMP) or as a Parallel Slave Port.
• CCP Modules: All devices in the family incorporate
two Capture/Compare/PWM (CCP) modules and
three Enhanced CCP (ECCP) modules to maximize
flexibility in control applications. Up to four different
time bases may be used to perform several
different operations at once. Each of the three
ECCP modules offers up to four PWM outputs,
allowing for a total of 12 PWMs. The ECCPs also
offer many beneficial features, including polarity
selection, programmable dead time, auto-shutdown
and restart, and Half-Bridge and Full-Bridge Output
modes.
• 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, reducing code overhead.
• Extended Watchdog Timer (WDT): This
enhanced version incorporates a 16-bit prescaler,
allowing an extended time-out range that is stable
across operating voltage and temperature. See
Section 28.0 “Electrical Characteristics” for
time-out periods.
1.3 Details on Individual Family
Members
Devices in the PIC18F87J11 family are available in
64-pin and 80-pin 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 three
ways:
1. Flash program memory (three sizes, ranging
from 64 Kbytes for PIC18FX6J11 devices to
128 Kbytes for PIC18FX7J11 devices).
2. I/O ports (7 bidirectional ports on 64-pin devices,
9 bidirectional ports on 80-pin devices).
3. A/D input channels (11 on 64-pin devices, 15 on
80-pin devices).
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2.
The pinouts for all devices are listed in Table 1-3 and
Table 1-4.
