PIC10F220/222
1.0 GENERAL DESCRIPTION
The PIC10F220/222 devices from Microchip
Technology are low-cost, high-performance, 8-bit, fully-
static Flash-based CMOS microcontrollers. They
employ a RISC architecture with only 33 single-word/
single-cycle instructions. All instructions are single-
cycle (1 μs) except for program branches, which take
two cycles. The PIC10F220/222 devices deliver perfor-
mance in an order of magnitude higher than their com-
petitors 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 PIC10F220/222 products are equipped with spe-
cial features that reduce system cost and power
requirements. The Power-on Reset (POR) and Device
Reset Timer (DRT) eliminates the need for the external
Reset circuitry. INTOSC Internal Oscillator mode is pro-
vided, thereby, preserving the limited number of I/O
available. Power-Saving Sleep mode, Watchdog Timer
and code protection features improve system cost,
power and reliability.
The PIC10F220/222 devices are available in cost-
effective Flash, 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 PIC10F220/222 products are supported by a full-
featured macro assembler, a software simulator, an in-
circuit debugger, a ‘C’ compiler, a low-cost
development programmer and a full featured program-
mer. All the tools are supported on IBM
®
PC and
compatible machines.
1.1 Applications
The PIC10F220/222 devices fit 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 fre-
quencies, etc.) extremely fast and convenient. The
small footprint packages, for through hole or surface
mounting, make these microcontrollers well suited for
applications with space limitations. Low-cost, low-
power, high-performance, ease-of-use and I/O flexibil-
ity make the PIC10F220/222 devices 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).
