PIC18F87J50 FAMILY

1.1.5
EXTERNAL MEMORY BUS
In the event that 128 Kbytes of memory are inadequate
for an application, the 80-pin members of the
PIC18F87J10 family also implement an External Mem-
ory Bus (EMB). 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. This allows additional memory
options, including:
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
1.1.6
EXTENDED INSTRUCTION SET
The PIC18F87J10 family implements the optional
extension to the PIC18 instruction set, adding 8 new
instructions and an Indexed Addressing mode.
Enabled as a device configuration option, the extension
has been specifically designed to optimize re-entrant
application code originally developed in high-level
languages, such as ‘C’.
1.1.7
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 PIC18F87J10 family is also pin compatible with
other PIC18 families, such as the PIC18F87J10,
PIC18F87J11, 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 PIC18F87J10 family
incorporates a range of serial and parallel com-
munication peripherals, including a fully featured
Universal Serial Bus communications module that
is compliant with the USB Specification
Revision 2.0. This device also includes 2 indepen-
dent Enhanced USARTs and 2 Master SSP
modules, capable of both SPI and I2C (Master
and Slave) modes of operation. The device also
has a parallel port and can be configured to serve
as either a Parallel Master Port or as a Parallel
Slave Port.
CCP Modules: All devices in the family incorporate
two Capture/Compare/PWM (CCP) modules and
three Enhanced CCP 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
ECCPs 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
time-out periods.
1.3
Details on Individual Family
Members
Devices in the PIC18F87J10 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 two
ways:
1.
Flash program memory (six sizes, ranging from
32 Kbytes
for
PIC18FX5J50
devices
to
128 Kbytes for PIC18FX7J50).
2.
I/O ports (7 bidirectional ports on 64-pin devices,
9 bidirectional ports on 80-pin devices).
All other features for devices in this family are identical.
The pinouts for all devices are listed in Table 1-3 and
