PIC18F87K22 FAMILY
1.0
DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
This family combines the traditional advantages of all
PIC18 microcontrollers – namely, high computational
performance and a rich feature set – with an extremely
competitive price point. These features make the
PIC18F87K22 family a logical choice for many
high-performance applications where price is a primary
consideration.
1.1
Core Features
1.1.1
nanoWatt TECHNOLOGY
All of the devices in the PIC18F87K22 family incorpo-
rate 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.
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.
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.
nanoWatt XLP: An extra low-power Sleep, BOR,
RTCC and Watchdog Timer
1.1.2
OSCILLATOR OPTIONS AND
FEATURES
All of the devices in the PIC18F87K22 family offer
different oscillator options, allowing users a range of
choices in developing application hardware. These
include:
External Resistor/Capacitor (RC); RA6 available
External Resistor/Capacitor with Clock Out
(RCIO)
Three External Clock modes:
- External Clock (EC); RA6 available
- External Clock with Clock Out (ECIO)
- External Crystal (XT, HS, LP)
A Phase Lock Loop (PLL) frequency multiplier,
available to the External Oscillator modes, which
allows clock speeds of up to 64 MHz. PLL can
also be used with the internal oscillator.
An internal oscillator block that provides a 16 MHz
clock (±2% accuracy) and an INTRC source
(approximately 31 kHz, stable over temperature
and VDD)
- Operates as HF-INTOSC or MF-INTOSC
when block selected for 16 MHz or 500 kHz
- Frees the two oscillator pins for use as
additional general purpose I/O
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.
1.1.3
MEMORY OPTIONS
The PIC18F87K22 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 up to 10,000 erase/write cycles. Data retention
without refresh is conservatively estimated to be
greater than 40 years.
The Flash program memory is readable and writable.
During normal operation, the PIC18F87K22 family also
provides plenty of room for dynamic application data
with up to 3,862 bytes of data RAM.
1.1.4
EXTERNAL MEMORY BUS
Should 128 Kbytes of memory be inadequate for an
application, the 80-pin members of the PIC18F87K22
family have an External Memory Bus (EMB) enabling
the controller’s internal Program Counter to address a
memory space of up to 2 Mbytes. This is a level of data
access that few 8-bit devices can claim and enables:
Using combinations of on-chip and external
memory of up to 2 Mbytes
Using external Flash memory for reprogrammable
application code or large data tables
Using external RAM devices for storing large
amounts of variable data
1.1.5
EXTENDED INSTRUCTION SET
The PIC18F87K22 family implements the optional
extension to the PIC18 instruction set, adding eight
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’.
