7 / 98 page  2004 Microchip Technology Inc. Preliminary DS41236A-page 5 PIC12F508/509/16F505 1.0 GENERAL DESCRIPTION The PIC12F508/509/16F505 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 single cycle (200 µs) except for program branches, which take two cycles. The PIC12F508/509/16F505 devices deliver performance 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. The PIC12F508/509/16F505 products are 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. There are four oscillator config- urations to choose from (six on the PIC16F505), includ- ing INTRC Internal Oscillator mode and the power- saving LP (Low-power) Oscillator mode. Power-saving Sleep mode, Watchdog Timer and code protection features improve system cost, power and reliability. The PIC12F508/509/16F505 devices are available in the cost-effective Flash programmable version, which is suitable for production in any volume. The customer can take full advantage of Microchip’s price leadership in Flash programmable microcontrollers, while benefiting from the Flash programmable flexibility. The PIC12F508/509/16F505 products are supported by a full-featured macro assembler, a software simula- tor, an in-circuit emulator, a ‘C’ compiler, a low-cost development programmer and a full featured program- mer. All the tools are supported on IBM® PC and compatible machines. 1.1 Applications 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 conve- nient. 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 versa- tile even in areas where no microcontroller use has been considered before (e.g., timer functions, logic and PLDs in larger systems and coprocessor applications).
