Description

The PIC12F508-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 PIC12F508 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.

Application

The PIC12F508/509/16F505 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 frequencies, etc.) extremely fast and convenient. The small footprint packages, for through hole or surface mounting, make these microcontrollers perfect for applications with space limitations. Low cost, low power, high performance, ease-of-use and I/O flexibility make the PIC12F508/509/16F505 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).
