PIC18F87J50 FAMILY
1.0
DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
This family introduces a new line of low-voltage USB
microcontrollers with the main traditional advantage of
all PIC18 microcontrollers – namely, high computa-
tional performance and a rich feature set – at an
extremely competitive price point. These features
make the PIC18F87J10 family a logical choice for
many high-performance applications, where cost is a
primary consideration.
1.1
Core Features
1.1.1
nanoWatt TECHNOLOGY
All of the devices in the PIC18F87J10 family incorporate
a range of features that can significantly reduce power
consumption during operation. Key items include:
Alternate Run Modes: By clocking the controller
from the Timer1 source or the internal RC oscilla-
tor, power consumption during code execution
can be reduced by as much as 90%.
Multiple Idle Modes: The controller can also run
with its CPU core disabled but the peripherals still
active. In these states, power consumption can be
reduced even further, to as little as 4% of normal
operation requirements.
On-the-Fly Mode Switching: The
power-managed modes are invoked by user code
during operation, allowing the user to incorporate
power-saving ideas into their application’s
software design.
1.1.2
UNIVERSAL SERIAL BUS (USB)
Devices in the PIC18F87J10 family incorporate a
fully-featured Universal Serial Bus communications
module with a built-in transceiver that is compliant with
the USB Specification Revision 2.0. The module
supports both low-speed and full-speed communication
for all supported data transfer types.
1.1.3
OSCILLATOR OPTIONS AND
FEATURES
All of the devices in the PIC18F87J10 family offer five
different oscillator options, allowing users a range of
choices in developing application hardware. These
include:
Two Crystal modes, using crystals or ceramic
resonators.
Two External Clock modes, offering the option of
a divide-by-4 clock output.
An internal oscillator block which provides an
8 MHz clock and an INTRC source (approxi-
mately 31 kHz, stable over temperature and VDD),
as well as a range of 6 user-selectable clock
frequencies, between 125 kHz to 4 MHz, for a
total of 8 clock frequencies. This option frees an
oscillator pin for use as an additional general
purpose I/O.
A Phase Lock Loop (PLL) frequency multiplier,
available to the high-speed crystal, external
oscillator and internal oscillator, providing a clock
speed up to 48 MHz.
Dual clock operation, allowing the USB module to
run from a high-frequency oscillator while the rest
of the microcontroller is clocked at a different
frequency.
The internal oscillator block provides a stable reference
source that gives the family additional features for
robust operation:
Fail-Safe Clock Monitor: This option constantly
monitors the main clock source against a reference
signal provided by the internal oscillator. If a clock
failure occurs, the controller is switched to the
internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
Two-Speed Start-up: This option allows the
internal oscillator to serve as the clock source
from Power-on Reset, or wake-up from Sleep
mode, until the primary clock source is available.
1.1.4
EXPANDED MEMORY
The PIC18F87J10 family provides ample room for
application code, from 32 Kbytes to 128 Kbytes of code
space. The Flash cells for program memory are rated
to last in excess of 10000 erase/write cycles. Data
retention without refresh is conservatively estimated to
be greater than 20 years.
The Flash program memory is readable and writable
during normal operation. The PIC18F87J10 family also
provides plenty of room for dynamic application data
with up to 3904 bytes of data RAM.
