PIC MICROCONTROLLER
Page Contents
 
PIC stands for peripheral interface controller
Whereas F stands for Flash it represents the type of memory used,
In 2000, Microchip introduced the PIC18 architecture.Unlike the 17 series,with a large number of device variants presently in manufacture. In contrast to earlier devices, which were more often than not programmed in assembly, C has become the predominant development language.

Advantages
- Small instruction set to learn and implement
- PIC has RISC architecture
- Built-in oscillator with selectable speeds
- Easy entry level, in-circuit programming plus in-circuit debugging PICkit units available for less than $50
- Inexpensive microcontrollers
- Wide range of interfaces including I²C, SPI, USB, USART, A/D, programmable comparators, PWM, LIN, CAN, PSP, and Ethernet
- Availability of processors in DIL package make them easy to handle for hobby use.
Comparison between PIC Microcontroller and 8051Â Microcontroller
8051- if u want a cheap controller with basic functions then 8051 will suffice . It will be of great use in your low-cost college projects.
PIC- Cheap , used in refrigerators and low budget projects .
8051 and PIC need multiple clock cycles per instruction. AVR and ARM execute most instructions in a single clock cycle.
8051 and PIC have limited stack space – limited to 128 bytes for the 8051, and as little as 8 words or less for PIC. Writing a C compiler for these architectures must have been challenging, and compiler choice is limited.
