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.
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 Website 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., DS30000000A is version A of document DS30000000).
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 Website;
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), Brown-out
Reset (BOR) 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).
