The advantages of a bootloader over ICSP is faster programming speeds, immediate program execution following programming, and the ability to both debug and program using the same cable. There are many programmers for PIC microcontrollers, ranging from the extremely simple designs which rely on ICSP to allow direct download of code from a host computer, to intelligent programmers that can verify the device at several supply voltages. Many of these complex programmers use a pre-programmed PIC themselves to send the programming commands to the PIC that is to be programmed.
Third party programmers range from plans to build your own, to self-assembly kits and fully tested ready-to-go units.

Some are simple designs which require a PC to do the low-level programming signalling these typically connect to the serial or parallel port and consist of a few simple components , while others have the programming logic built into them these typically use a serial or USB connection, are usually faster, and are often built using PICs themselves for control. Some devices do not have on-chip debug support, due to cost or lack of pins. Some larger chips also have no debug module. To debug these devices, a special -ICD version of the chip mounted on a daughter board which provides dedicated ports is required.
Some of these debug chips are able to operate as more than one type of chip by the use of selectable jumpers on the daughter board. This allows broadly identical architectures that do not feature all the on chip peripheral devices to be replaced by a single -ICD chip. For example: the 12FICD will function as one of six different parts each of which features one, some or all of five on chip peripherals.

This brings a familiar Unix-like operating system, including an onboard development environment, to the microcontroller, within the constraints of the onboard hardware. It is currently discontinued. They include up to bit words of flash memory and up to bytes of random access memory , an eight bit counter and other support logic. Other interfaces are relatively easy to write, and existing modules can be modified to get new features. Holtek Semiconductor make a large number of very cheap microcontrollers  as low as 8. Many ultra-low-cost OTP microcontrollers from Asian manufacturers, found in low-cost consumer electronics are based on the PIC architecture or modified form.
Microchip has attempted to sue some manufacturers when the copying is particularly egregious,   without success.

Microcontrollers for Students: The Theory - Dogan Ibrahim - Google книги
Please lead me about micro-controller circuit design and programming for my electronics research paper…. I need it urgently because i have no enough time for my research paper and about its presentation….
go to link I must so excited for this great Chip which is caperbel of performing Multi functions ranging from Toys to Robotics applications. Bravo to the Manufacturers! I hav checked on the different types of the Microcontrollers, but they are dozens from different Companies.
Therefore; I would like to know which one is most suitable for Automotive applications and as well the Configuration of the Pins in many different circuits. Thanks, Hope Ill find my answers.
