Pic İntroduction

Pic introduction 

What are PICs?

PIC is a type of microcontrollers that made Microchip company

generally the pics are 8 bit microprocessors with small rom,ram and simple peripherals packaged on a single chip.

What is the mean of PIC?

first letter of Perriperal Interface Conroller.

The pics name begins with a number. for example 12,16,17,18 (like 16F84 and 16f877,16F628 etc.)
16 Indicate the most popular one at the moment, 14 bit core processor wide selection range

12 Usually indicates small 8 pin devices, and ideal for simple circuits.
tne number 18 Are the new 16 bit models.
