DEVICE OVERVIEW
This document contains device specific information for
the operation of the PIC16F818/819 devices.
Additional information may be found in the PICmicro
TM
Mid-Range MCU Reference Manual (DS33023), which
may be downloaded from the Microchip web site. The
Reference Manual should be considered a comple-
mentary document to this data sheet, and is highly rec-
ommended 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 sys-
tem clock via the configuration bits. Refer to
Section 4.5 and Section 12.1 for further details.
The Timer1 module current consumption has
been greatly reduced from 20 μA (previous PIC16
devices) to 1.3
μ
A typical (32 kHz at 2V), which is
ideal for real-time clock applications. Refer to
Section 6.0 for further details.
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
(F
OSC
/4). An external clock can be configured
with an I/O pin. Refer to Section 4.0 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/I

C
MCLR (RA5) can be configured as an Input
Table 1-2 details the pinout of the device with
descriptions and details for each pin.
