The PIC12F510 device is low-cost, high-performance, 8-bit, fullystatic, Flash-based CMOS micro controllers. They employ a RISC architecture with only 33 single-word/ single-cycle instructions. All instructions are single cycle except for program branches, which take two cycles. The PIC12F510 devices deliver performance in an order of a 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 micro controllers in its class. The easy-to-use and easy to-remember instruction set reduces development time significantly. The PIC12F510 product is 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 configurations to choose from (six on the PIC16F506), including INTOSC 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 PIC12F510 device allow the customer to take full advantage of Microchip?s price leadership in Flash programmable micro controllers, while benefiting from the Flash programmable flexibility. The PIC12F510 products are supported by a full-featured macro assembler, a software simulator, an in-circuit emulator, a ?C? compiler, a low-cost development programmer and a full featured programmer.

The PIC16C622 device has enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance. PIC16C622 micro controllers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit micro controllers in their class.
