The PIC16C505 from Microchip Technology is a low-

cost, high performance, 8-bit, fully static, EPROM/

ROM-based CMOS microcontroller. It employs a RISC

architecture with only 33 single word/single cycle

instructions. All instructions are single cycle (1 µs)

except for program branches which take two cycles.

The PIC16C505 delivers performance an order of mag-

nitude higher than its competitors in the same price cat-

The PIC16C505 fits perfectly in applications ranging

from personal care appliances and security systems to

low-power remote transmitters/receivers. The EPROM

technology makes customizing application programs

(transmitter codes, appliance settings, receiver fre-

quencies, etc.) extremely fast and convenient. The

small footprint packages, for through hole or surface

mounting, make this microcontroller perfect for applica-

egory. The 12-bit wide instructions

are highly

tions with space limitations. Low-cost, low-power, high

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 PIC16C505 product is equipped with special fea-

tures 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 five 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 PIC16C505 is available in the cost-effective One-

Time-Programmable (OTP) version, which is 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


The PIC16C505 product is supported by a full-featured

macro assembler, a software simulator, an in-circuit

emulator, a ‘C’ compiler, a low-cost development pro-

grammer, and a full featured programmer. All the tools

are supported on IBM® PC and compatible machines.

performance, ease of use and I/O flexibility make the

PIC16C505 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, coprocess
