GENERAL DESCRIPTION

The PIC16F527 device from Microchip Technology is a

low-cost, high-performance, 8-bit, fully-static, Flash-

based CMOS microcontroller. It employs a RISC

architecture with only 36 single-word/single-cycle

instructions. All instructions are single cycle except for

program branches, which take two cycles. The

PIC16F527 device delivers performance an order of

magnitude higher than its competitors in the same price

category. The 12-bit wide instructions are highly

symmetrical,

resulting

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 PIC16F527 product is equipped with special

features 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

several

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 PIC16F527 device is available in the cost-effective

Flash programmable version, which is suitable for

production in any volume. The customer can take full

advantage of Microchip’s price leadership in Flash

programmable microcontrollers, while benefiting from

the Flash programmable flexibility.

The PIC16F527 product is supported by a full-featured

macro assembler, a software simulator, an in-circuit

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

programmer and a full-featured programmer. All the

tools are supported on IBM® PC and compatible

machines.

1.1

Applications

The PIC16F527 device fits in applications ranging from

personal care appliances and security systems to low-

power remote transmitters/receivers. The Flash

technology makes customizing application programs

(transmitter codes,

appliance settings,

receiver

frequencies, etc.) extremely fast and convenient. The

small footprint packages, for through hole or surface

mounting, make these microcontrollers perfect for

applications with space limitations. Low cost, low

power, high performance, ease of use and I/O flexibility

make the PIC16F527 device very versatile, even in

areas where no microcontroller use has been

considered before (e.g., timer functions, logic and

PLDs in larger systems and coprocessor applications).
