Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

GENERAL DESCRIPTION
The PIC12F529T48A device from Microchip
Technology is a low-cost, high-performance, 8-bit, fully-
static, Flash-based CMOS microcontroller. It employs a
RISC architecture with only 34 single-word/single-cycle
instructions. All instructions are single cycle except for
program branches, which take two cycles. The
PIC12F529T48A 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 PIC12F529T48A 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 PIC12F529T48A 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 PIC12F529T48A product is supported by a full-
featured macro assembler, a software simulator, a low-
cost development programmer and a full-featured
programmer. All the tools are supported on PC and
compatible machines.
1.1
Applications
The PIC12F529T48A 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 PIC12F529T48A device very versatile even
in areas where no microcontroller use has been
considered before (e.g., timer functions, logic and
programmable logic devices (PLDs) in larger systems
and coprocessor applications).

VARIETIES
When placing orders, please use the PIC12F529T48A
Product Identification System at the back of this data
sheet to specify the correct part number. 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.
