GENERAL DESCRIPTION  
The PIC12C5XX from Microchip Technology is a fam-  
ily of low-cost, high performance, 8-bit, fully static,  
EEPROM/EPROM/ROM-based CMOS microcontrol-  
lers. It employs a RISC architecture with only 33 sin-  
gle word/single cycle instructions. All instructions are  
single cycle (1 µs) except for program branches  
which take two cycles. The PIC12C5XX delivers per-  
formance an order of magnitude higher than its com-  
petitors 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 signifi-  
cantly.  
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, while the EEPROM data memory technology  
allows for the changing of calibration factors and secu-  
rity codes. The small footprint packages, for through  
hole or surface mounting, make this microcontroller  
series perfect for applications with space limitations.  
Low-cost, low-power, high performance, ease of use  
and I/O flexibility make the PIC12C5XX series very ver-  
satile even in areas where no microcontroller use has  
been considered before (e.g., timer functions, replace-  
ment of “glue” logic and PLD’s in larger systems, copro-  
cessor applications).  
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 mode. Power  
saving SLEEP mode, Watchdog Timer and code  
protection features also 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.
