GENERAL DESCRIPTION
The PIC12F519 device from Microchip Technology is
low-cost, high-performance, 8-bit, fully-static, Flash-
based CMOS microcontrollers. They employ a RISC
architecture with only 33 single-word/single-cycle
instructions. All instructions are single cycle except for
program branches, which take two cycles. The
PIC12F519 device delivers performance an order of
magnitude higher than their competitors in the same
price category. The 12-bit wide instructions are highly
symmetrical, resulting in a typical 2:1 code
compression over other 8-bit microcontrollers in its
class. The easy-to-use and easy to remember
instruction set reduces development time significantly.
The PIC12F519 product is equipped with special
features that reduce system cost and power
requirements. The Power-on Reset (POR) and Device
Reset Timer (DRT) eliminate the need for external
Reset circuitry. There are four oscillator configurations
to choose from including INTRC Internal Oscillator
mode and the power-saving LP (Low-power) Oscillator
mode. Power-Saving Sleep mode, Watchdog Timer
and code protection features improve system cost,
power and reliability.
The PIC12F519 device is available in the cost-effective
Flash programmable version, which is suitable for
production in any volume. The customer can take full
advantage of Microchip’s price leadership in Flash
programmable microcontrollers, while benefiting from
the Flash programmable flexibility.
The PIC12F519 product 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. All the tools are supported on
PC and compatible machines.
1.1
Applications
The PIC12F519 device fits in applications ranging from
personal care appliances and security systems to low-
power remote transmitters/receivers. The Flash
technology makes customizing application programs
(transmitter codes, appliance settings, receiver
frequencies, etc.) extremely fast and convenient. The
small footprint packages, for through hole or surface
mounting, make these microcontrollers perfect for
applications with space limitations. Low cost, low
power, high performance, ease of use and I/O flexibility
make the PIC12F519 device very versatile even in
areas where no microcontroller use has been
considered before (e.g., timer functions, logic and
PLDs in larger systems and coprocessor applications).

PIC12F519 DEVICE VARIETIES
When placing orders, please use the PIC12F519
Product Identification System at the back of this data
sheet to specify the correct part number. A variety of
packaging options are available. Depending on
application and production requirements, the proper
device option can be selected using the information in
this section.
2.1
Quick Turn Programming (QTP)
Devices
Microchip offers a QTP programming service for factory
production orders. This service is made available for
users who choose not to program medium-to-high
quantity units and whose code patterns have stabilized.
The devices are identical to the Flash devices but with
all Flash locations and fuse options already
programmed by the factory. Certain code and prototype
verification procedures do apply before production
shipments are available. Please contact your local
Microchip Technology sales office for more details.
2.2
Serialized Quick Turn
Programming
SM
(SQTP
SM
) Devices
Microchip offers a unique programming service, where a
few user-defined locations in each device are
programmed with different serial numbers. The serial
numbers may be random, pseudo-random or sequential.
Serial programming allows each device to have a
unique number, which can serve as an entry code,
password or ID number.
