Product Description

PIC12F508 – Microcontrollers and Processors 

PIC12F508 – Microcontrollers and Processors. devices from MicrochipTechnology 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 μs) 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 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 configurations
to choose from (six on the PIC16F505), 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 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 Flash programmable microcontrollers, while
benefiting from the Flash programmable flexibility.
The PIC12F508/509/16F505 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 programmer.
All the tools are supported on IBM® PC and
compatible machines
