TO OUR VALUED CUSTOMERS

It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip

products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and

enhanced as new volumes and updates are introduced.

If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via

E-mail at

docerrors@microchip.com

or fax the

Reader Response Form

in the back of this data sheet to (480) 792-4150. We

welcome your feedback.

Most Current Data Sheet

To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:

http://www.microchip.com

You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.

The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).

Errata

An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current

devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision

of silicon and revision of document to which it applies.

To determine if an errata sheet exists for a particular device, please check with one of the following:

• Microchip’s Worldwide Web site;

http://www.microchip.com

• Your local Microchip sales office (see last page)

When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are

using.

GENERAL DESCRIPTION

1.1

Applications

The PIC16F570 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

PIC16F570 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 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 PIC16F570 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 PIC16F570 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 PIC16F570 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.

The PIC16F570 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 PIC16F570 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 co-processor

applications).
