PIC16F676-I/P

The PIC12F509 device is low-cost, high-performance, 8-bit, fully-static, Flash-based CMOS micro controllers. They employ a RISC architecture with only 33 single-word/ single-cycle instructions. All instructions are single cycle (200 ?s) except for program branches, which take two cycles. The device 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 micro controllers in its class. The easy to use and easy to remember instruction set reduces development time significantly. It 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 PIC16F505), including 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 device is 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 micro controllers, while benefiting from the Flash programmable flexibility. It is 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. All the tools are supported on IBM? PC and compatible machines.

The PIC16F628A is 18-pin Flash-based members of the versatile PIC16F628A family of low-cost, high-performance, CMOS, fullystatic, 8-bit microcontrollers. All PIC? microcontrollers employ an advanced RISC architecture. The PIC16F628A have enhanced core features, an 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, complemented by a large register set.

PIC16F676 is powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS Flash-based 8-bit microcontroller packs Microchip?s powerful PIC? MCU architecture into a 14-pin package and features 8 channels for the 10-bit Analog-to-Digital (A/D) converter, 1 comparator and 128 bytes of EEPROM data memory. This device is easily adapted for automotive, industrial, appliances and consumer entry-level product applications that require field re-programmability.
