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 singlecycle (1 ¦Ìs) except for program branches, which take two cycles. The PIC10F220/222 devices deliver performance in an order of magnitude higher than their 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.
