PIC12F509I/SN

Product Summary

The PIC12F509I/SN is an 8-Bit Flash Microcontroller. It 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 PIC12F509I/SN 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 PIC12F509I/SN is equipped with special features that reduce system cost and power requirements.
