1.0
The PIC12C5XX from Microchip Technology is a family
of low-cost, high performance, 8-bit, fully static,
EPROM/ROM-based
employs a RISC architecture with only 33 single word/
single cycle instructions. All instructions are single
cycle (1 s) except for program branches which take
two cycles. The PIC12C5XX delivers performance an
order of magnitude higher than its competitors in the
same price category. The 12-bit wide instructions are
highly symmetrical resulting in 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 PIC12C5XX products are equipped with special
features that reduce system cost and power require-
ments. The Power-On Reset (POR) and Device Reset
Timer (DRT) eliminate the need for external reset cir-
cuitry. There are four oscillator configurations to
choose from, including INTRC internal oscillator mode
and the power-saving LP (Low Power) oscillator.
Power saving SLEEP mode, Watchdog Timer and code
protection features improve system cost, power and
reliability.
The PIC12C5XX are available in the cost-effective
One-Time-Programmable (OTP) versions which are
suitable for production in any volume. The customer
can take full advantage of Microchip’s price leadership
in OTP microcontrollers while benefiting from the
OTP’s flexibility.
The PIC12C5XX products are supported by a full-fea-
tured macro assembler, a software simulator, an in-cir-
cuit emulator, a ‘C’ compiler, fuzzy logic support tools,
a low-cost development programmer, and a full fea-
tured programmer. All the tools are supported on IBM
PC and compatible machines.

Advance Information
It
1.1
The PIC12C5XX series fits perfectly in applications
ranging from personal care appliances and security
systems to low-power remote transmitters/receivers.
The EPROM technology makes customizing applica-
tion programs (transmitter codes, appliance settings,
receiver frequencies, etc.) extremely fast and conve-
nient. The small footprint packages, for through hole or
surface mounting, make this microcontroller series per-
fect for applications with space limitations. Low-cost,
low-power, high performance, ease of use and I/O flex-
ibility make the PIC12C5XX series very versatile even
in areas where no microcontroller use has been
considered before (e.g., timer functions, replacement
of “glue” logic and PLD’s in larger systems, coproces-
sor applications).
