1.0
The PIC12F508/509/16F505 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 (200 s) except for program branches, which
take two cycles. The PIC12F508/509/16F505 devices
deliver 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 PIC12F508/509/16F505 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 config-
urations to choose from (six on the PIC16F505), includ-
ing 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 PIC12F508/509/16F505 devices are 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
benefiting from the Flash programmable flexibility.
The PIC12F508/509/16F505 products are supported
by a full-featured macro assembler, a software simula-
tor, 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
compatible machines.

1.1
The PIC12F508/509/16F505 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 flexibility
make the PIC12F508/509/16F505 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).
