GENERAL DESCRIPTION
1.1
Applications
The PIC16C5X from Microchip Technology is a family
of low-cost, high performance, 8-bit, fully static,
EPROM/ ROM-based CMOS microcontrollers. It
employs a RISC architecture with only 33 single
word/single cycle instructions. All instructions are sin-
gle cycle (200 ns) except for program branches which
take two cycles. The PIC16C5X 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 PIC16C5X products are 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 four oscillator configurations to choose from,
including the power-saving LP (Low Power) oscillator
and cost saving RC oscillator. Power saving SLEEP
mode, Watchdog Timer and code protection features
improve system cost, power and reliability.
The UV erasable CERDIP packaged versions are ideal
for code development, while the cost-effective One
Time Programmable (OTP) versions 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 PIC16C5X products are supported by a
full-featured macro assembler, a software simulator, an
in-circuit emulator, a ‘C’ compiler, fuzzy logic support
tools, a low-cost development programmer, and a full
featured programmer. All the tools are supported on
IBM
®
PC and compatible machines.
The PIC16C5X series fits perfectly in applications rang-
ing from high-speed automotive and appliance motor
control to low-power remote transmitters/receivers,
pointing devices and telecom processors. The EPROM
technology makes customizing application programs
(transmitter codes, motor speeds, receiver frequen-
cies, etc.) extremely fast and convenient. The small
footprint packages, for through hole or surface mount-
ing, make this microcontroller series perfect for applica-
tions with space limitations. Low-cost, low-power, high
performance, ease of use and I/O flexibility make the
PIC16C5X series very versatile even in areas where no
microcontroller use has been considered before (e.g.,
timer functions, replacement of “glue” logic in larger
systems, coprocessor applications).
