The PIC12F509-I/P is a 8-bit high-performance fully-static Flash-based CMOS Microcontroller employs a RISC architecture with only 33 single-word/single-cycle instructions. All instructions are single cycle (200μs) except for program branches, which take two cycles. The PIC12F509 device delivers performance an order of magnitude higher than their competitors. 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. Equipped with special features that reduce system cost and power requirements. The Power-on reset (POR) and device reset timer (DRT) eliminate the need for external reset circuitry.
