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).
