 16C505
1.0 GENERAL DESCRIPTION
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 (200 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-
egory. 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 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 mode. 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
flexibility.
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.
PIC16C505
1.1 Applications
The PIC16C505 fits in applications ranging from per-
sonal 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-
tions with space limitations. Low-cost, low-power, high
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, coprocessor applications).
