TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at docerrors@microchip.com or fax the Reader Response Form in the back of this data sheet to (480) 792-4150. We
welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are

GENERAL DESCRIPTION
The PIC12F510/16F506 devices from Microchip
Technology are 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 PIC12F510/16F506 devices deliver
performance in 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 PIC12F510/16F506 products are 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 con-
figurations to choose from (six on the PIC16F506),
including INTOSC 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 PIC12F510/16F506 devices allow the customer to
take full advantage of Microchip’s price leadership in
Flash programmable microcontrollers, while benefiting
from the Flash programmable flexibility.
The PIC12F510/16F506 products are supported by a
full-featured macro assembler, a software simulator, an
in-circuit emulator, a ‘C’ compiler, a low-cost
development programmer and a full featured program-
mer. All the tools are supported on IBM
®
PC and
compatible machines.
1.1
Applications
The PIC12F510/16F506 devices fit 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 conve-
nient. 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 flexibil-
ity make the PIC12F510/16F506 devices very versa-
tile, even in areas where no microcontroller use has
been considered before (e.g., timer functions, logic and
PLDs in larger systems and coprocessor applications).

VARIETIES
A variety of packaging options are available. Depend-
ing on application and production requirements, the
proper device option can be selected using the
information in this section. When placing orders, please
use the PIC12F510/16F506 Product Identification
System at the back of this data sheet to specify the
correct part number.
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.
