1.0
The PIC16C84 is a low-cost, high-performance,
CMOS, fully-static, 8-bit microcontroller.
All PIC16/17 microcontrollers employ an advanced
RISC architecture. PIC16CXX devices have enhanced
core features, eight-level deep stack, and multiple inter-
nal and external interrupt sources. The separate
instruction and data buses of the Harvard architecture
allow a 14-bit wide instruction word with a separate
8-bit wide data bus. The two stage instruction pipeline
allows all instructions to execute in a single cycle,
except for program branches (which require two
cycles). A total of 35 instructions (reduced instruction
set) are available. Additionally, a large register set is
used to achieve a very high performance level.
PIC16CXX microcontrollers typically achieve a 2:1
code compression and up to a 2:1 speed improvement
(at 10 MHz) over other 8-bit microcontrollers in their
class.
The PIC16C84 has 36 bytes of RAM, 64 bytes of Data
EEPROM memory, and 13 I/O pins. A timer/counter is
also available.
The PIC16CXX family has special features to reduce
external components, thus reducing cost, enhancing
system reliability and reducing power consumption.
There are four oscillator options, of which the single pin
RC oscillator provides a low-cost solution, the LP
oscillator minimizes power consumption, XT is a
standard crystal, and the HS is for High Speed crystals.
The SLEEP (power-down) mode offers power savings.
The user can wake the chip from sleep through several
external and internal interrupts and resets.
A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software lock-
up.
The PIC16C84 EEPROM program memory allows the
same device package to be used for prototyping and
production. In-circuit reprogrammability allows the
code to be updated without the device being removed
from the end application. This is useful in the
development of many applications where the device
may not be easily accessible, but the prototypes may
require code updates. This is also useful for remote
applications where the code may need to be updated
(such as rate information).
Table 1-1 lists the features of the PIC16C84. A simpli-
fied block diagram of the PIC16C84 is shown in
Figure 3-1.

GENERAL DESCRIPTION
The PIC16C84 fits perfectly in applications ranging
from high speed automotive and appliance motor
control to low-power remote sensors, electronic locks,
security devices and smart cards. The EEPROM
technology
programs (transmitter codes, motor speeds, receiver
frequencies, security codes, etc.) extremely fast and
convenient. The small footprint packages make this
microcontroller series perfect for all applications with
space
performance, ease of use and I/O flexibility make the
PIC16C84 very versatile even in areas where no
microcontroller use has been considered before
(e.g., timer functions, serial communication, capture
and compare, PWM functions and co-processor
applications).
The serial in-system programming feature (via two
pins) offers flexibility of customizing the product after
complete assembly and testing. This feature can be
used to serialize a product, store calibration data, or
program the device with the current firmware before
shipping.
1.1
Those users familiar with the PIC16C5X family of
microcontrollers will realize that this is an enhanced
version of the PIC16C5X architecture. Please refer to
Appendix A for a detailed list of enhancements. Code
written for PIC16C5X can be easily ported to the
PIC16C84 (Appendix B).
1.2
The PIC16CXX family is supported by a full-featured
macro assembler, a software simulator, an in-circuit
emulator, a low-cost development programmer and a
full-featured programmer. A “C” compiler and fuzzy
logic support tools are also available.
