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 a versatile
on-chip LCD driver, while maintaining an extremely
competitive price point. These features make the
PIC18F87K90 family a logical choice for many
high-performance applications where price is a primary
consideration.

All of the devices in the PIC18F87K90 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
• Multiple Idle Modes: The controller can also run
• On-the-Fly Mode Switching: The power-managed
• nanoWatt XLP: An extra low-power BOR, RTCC
1.1.2
All of the devices in the PIC18F87K90 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
• Three External Clock modes:

PIC18F87K90 FAMILY
• An internal oscillator block that provides a 16 MHz
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
• Two-Speed Start-up: This option allows the
1.1.3
The PIC18F87K90 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 PIC18F87K90 family also
provides plenty of room for dynamic application data
with up to 3,828 bytes of data RAM.
1.1.4
The PIC18F87K90 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’.
1.1.5
Regardless of the memory size, all devices share the
same rich set of peripherals (except the 32-Kbyte parts,
which have two less CCPs and three less Timers),
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.
