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.

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:

Flash program memory (three sizes, ranging

from 64 Kbytes for PIC18FX6J11 devices to

128 Kbytes for PIC18FX7J11 devices).

I/O ports (7 bidirectional ports on 64-pin devices,

9 bidirectional ports on 80-pin devices).

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.
