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.
