PIC16F690 Microcontroller

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 PIC12F675 has a 13-bit program counter capable of addressing an 8K x 14 program memory space. The data memory is partitioned into two banks, which contain the General Purpose Registers and the Special Function Registers. The register file is organized as 64 x 8 in the PIC12F675 device. Each register is accessed, either directly or indirectly, through the File Select Register FSR. There are as many as six general purpose I/O pins available. Depending on which peripherals are enabled, some or all of the pins may not be available as general purpose I/O. In general, when a peripheral is enabled, the associated pin may not be used as a general purpose I/O pin.

The PIC16C83A is 8-Bit CMOS EEPROM Microcontrollers?Transceiver. PIC16C83A microcontrollers typically achieve a 2:1 code compression and up to a 2:1 speed improvement (at 10 MHz) over other 8-bit microcontrollers in their class. The PIC16C83A has up to 68 bytes of RAM, 64 bytes of Data EEPROM memory, and 13 I/O pins. A timer/counter is also available.

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.
