DEVICE OVERVIEW
This document contains device specific information for
the following devices:
This family offers the advantages of all PIC18 microcon-
trollers – namely, high computational performance at an
economical price – with the addition of high endurance
Enhanced Flash program memory. On top of these fea-
tures, the PIC18F1220/1320 family introduces design
enhancements that make these microcontrollers a logical
choice for many high-performance, power sensitive
applications.
1.1
New Core Features
1.1.1
nanoWatt TECHNOLOGY
All of the devices in the PIC18F1220/1320 family incor-
porate 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 oscillator
block, 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 are
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.
Lower Consumption in Key Modules: The power
requirements for both Timer1 and the Watchdog
Timer have been reduced by up to 80%, with typical
values of 1.1 and 2.1
μA, respectively.
1.1.2
MULTIPLE OSCILLATOR OPTIONS
AND FEATURES
All of the devices in the PIC18F1220/1320 family offer
nine different oscillator options, allowing users a wide
range of choices in developing application hardware.
These include:
Four Crystal modes, using crystals or ceramic
resonators.
Two External Clock modes, offering the option of
using two pins (oscillator input and a divide-by-4
clock output), or one pin (oscillator input, with the
second pin reassigned as general I/O).
Two External RC Oscillator modes, with the same
pin options as the External Clock modes.
An internal oscillator block, which provides an
8 MHz clock (±2% accuracy) and an INTRC source
(approximately 31 kHz, stable over temperature and
VDD), as well as a range of 6 user-selectable clock
frequencies (from 125 kHz to 4 MHz) for a total of
8 clock frequencies.
Besides its availability as a clock source, 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 fail-
ure occurs, the controller is switched to the internal
oscillator block, 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. This allows for
code execution during what would otherwise be the
clock start-up interval and can even allow an appli-
cation to perform routine background activities and
return to Sleep without returning to full power
operation.
1.2
Other Special Features
Memory Endurance: The Enhanced Flash cells for
both program memory and data EEPROM are rated
to last for many thousands of erase/write cycles –
up to 100,000 for program memory and 1,000,000
for EEPROM. Data retention without refresh is
conservatively
estimated
to
be
greater
than
40 years.
Self-programmability: These devices can write to
their own program memory spaces under internal
software control. By using a bootloader routine
located in the protected Boot Block at the top of pro-
gram memory, it becomes possible to create an
application that can update itself in the field.
Enhanced CCP module: In PWM mode, this
module provides 1, 2 or 4 modulated outputs for
controlling half-bridge and full-bridge drivers. Other
features include auto-shutdown, for disabling PWM
outputs on interrupt or other select conditions and
auto-restart, to reactivate outputs once the condition
has cleared.
Enhanced USART: This serial communication
module features automatic wake-up on Start bit and
automatic baud rate detection and supports RS-232,
RS-485 and LIN 1.2 protocols, making it ideally
suited for use in Local Interconnect Network (LIN)
bus applications.
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, reduce code overhead.
Extended Watchdog Timer (WDT): This enhanced
version incorporates a 16-bit prescaler, allowing a
time-out range from 4 ms to over 2 minutes that is
stable across operating voltage and temperature.
