DEVICE OVERVIEW
This document contains device specific information for
the operation of the PIC16F818/819 devices. Additional
information may be found in the “PICmicro Mid-Range
MCU Family Reference Manual” (DS33023) which may
be downloaded from the Microchip web site. The
Reference Manual should be considered a complemen-
tary document to this data sheet and is highly
recommended reading for a better understanding of the
device architecture and operation of the peripheral
modules.
The PIC16F818/819 belongs to the Mid-Range family
of the PICmicro devices. The devices differ from each
other in the amount of Flash program memory, data
memory and data EEPROM (see Table 1-1). A block
diagram of the devices is shown in Figure 1-1. These
devices contain features that are new to the PIC16
product line:
Internal RC oscillator with eight selectable
frequencies, including 31.25 kHz, 125 kHz,
250 kHz, 500 kHz, 1 MHz, 2 MHz, 4 MHz and
8 MHz. The INTRC can be configured as the
system clock via the configuration bits. Refer to
details.
The Timer1 module current consumption has
been greatly reduced from 20
A (previous PIC16
devices) to 1.8
A typical (32 kHz at 2V), which is
ideal for real-time clock applications. Refer to
The amount of oscillator selections has increased.
The RC and INTRC modes can be selected with
an I/O pin configured as an I/O or a clock output
(FOSC/4). An external clock can be configured
with an I/O pin. Refer to Section 4.0 “Oscillator
Configurations” for further details.
TABLE 1-1:
AVAILABLE MEMORY IN
PIC16F818/819 DEVICES
There are 16 I/O pins that are user configurable on a
pin-to-pin basis. Some pins are multiplexed with other
device functions. These functions include:
External Interrupt
Change on PORTB Interrupt
Timer0 Clock Input
Low-Power Timer1 Clock/Oscillator
Capture/Compare/PWM
10-bit, 5-channel Analog-to-Digital Converter
SPI/I2C
MCLR (RA5) can be configured as an Input
Table 1-2 details the pinout of the devices with
descriptions and details for each pin.
