PIC12F508-I/SN

Product Summary

The PIC12F508-I/SN is a low-cost, high-performance, 8-bit, fullystatic, Flash-based CMOS microcontroller. The PIC12F508-I/SN employs a RISC architecture with only 33 single word/single cycle instructions. All instructions are single cycle (200 μs) except for program branches, which take two cycles. The PIC12F508-I/SN delivers performance an order of magnitude higher than their competitors in the same price category. The PIC12F508-I/SN 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.
