PIC18F25K22 Microcontroller

The PIC12F629 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 PIC12F629 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 PIC16C54 is powerful (200 nanosecond instruction execution) yet easy-to-program (only 33 single-word instructions) FLASH-based 8-bit micro controller packs Microchip?s powerful PICmicro? architecture into an 18-pin package. Easily adapted for automotive, industrial, appliances and consumer entry-level product applications.

The PIC16C57 from Microchip Technology is a family of low cost, high performance, 8-bit fully static, EPROM/ROM-based CMOS micro controllers. It employs 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 PIC16C57 delivers performance in an order of magnitude higher than its competitors in the same price category. The 12-bit wide instructions are highly symmetrical resulting in 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 PIC16C57 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 configurations to choose from, including the power saving LP (Low Power) oscillator and cost saving RC oscillator.

The PIC16F73 is a 28/40-Pin 8-Bit CMOS FLASH Microcontrollers . The following are the features:- ? Timer0: 8-bit timer/counter with 8-bit prescaler ? Timer1: 16-bit timer/counter with prescaler, can be incremented during SLEEP via external crystal/clock ? Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler ? Capture, Compare, PWM (CCP) module - Capture is 16-bit, max. resolution is 12.5 ns - Compare is 16-bit, max. resolution is 200 ns - PWM max. resolution is 10-bit
