What architecture is PIC microcontroller?
Harvard Architecture
The Harvard Architecture used by PIC Microcontrollers. PIC microcontrollers are based on the Harvard architecture where program and data busses are kept separate.
Which software is used for PIC microcontroller?
Program the PIC Microcontroller The PIC microcontroller programming is performed through ‘MP-Lab’ software. First instal the MP-Lab software, then select and install the compiler like CCS, GCC compiler, etc. Here ‘CCS C compiler’ is used for building the program.
What is PIC architecture?
PIC Microcontroller architecture is based on Harvard architecture and supports RISC architecture (Reduced Instruction Set Computer). PIC microcontroller architecture consists of memory organization (ram, rom, stack), CPU, timers, counter, ADC, DAC, serial communication, CCP module and I/O ports.
What is PIC give its applications?
PIC (Programmable Interface Controllers) microcontrollers are the worlds smallest microcontrollers that can be programmed to carry out a huge range of tasks. These microcontrollers are found in many electronic devices such as phones, computer control systems, alarm systems, embedded systems, etc.
What is microcontroller architecture?
A microcontroller is essentially a small computer on a chip. Like any computer, it has memory, and can be programmed to do calculations, receive input, and generate output. Unlike a PC, it incorporates memory, a CPU, peripherals and I/O interfaces into a single chip.
What is PIC microcontroller in embedded system?
PIC Microcontroller is the very smallest microcontroller in the world that can be designed to carry out a huge range of tasks. These microcontrollers are in electronic devices such as phones, computer, and Embedded Operating System etc. Also, the features of these microcontrollers are RAM, CCP, SSP, LCD, and ICSP, etc.
How do we program the PIC Microcontroller?
- Step 1: Build Hardware. Before doing any programming the first step is to build the hardware.
- Step 2: Get Software. These instructions will use XC8 compiler and MPLAB X IDE by Microchip.
- Step 3: Create New Project.
- Step 4: Build Parameters.
- Step 5: Set Configuration Bits.
- Step 6: Configure Oscillator.
What are the features of PIC microcontroller?

- Various crystal or RC oscillator configurations, or an external clock.
What are the blocks in microcontroller?
The main important blocks are explained below,
- CPU(Central Processing Unit) CPU is the main part of the microcontroller that actually does all the processing works.
- Oscillator and Timers. It is an electronic pulse signal generator circuit.
- Memory Units.
- Interrupts.
- Bus.
How many ports are there in PIC microcontroller?
5 Ports
PIC Basic Properties: IT has 5 Ports in total. ( PortA, PortB, PortC, PortD and PortE). It supports Serial Communication for which it has 2 Pins TX and RX.
What is the PIC microcontroller architecture?
Every PIC microcontroller architecture consists of some registers and stack where registers function as Random Access Memory (RAM) and stack saves the return addresses.
What is ADA/D module of PIC microcontroller?
A/D module of PIC microcontroller consists of 5 inputs for 28 pin devices and 8 inputs for 40 pin devices. The operation of the analog to digital converter is controlled by ADCON0 and ADCON1 special registers. The upper bits of the converter are stored in register ADRESH and lower bits of the converter are stored in register ADRESL.
How many interrupts are there in a PIC microcontroller?
PIC microcontroller consists of 20 internal interrupts and three external interrupt sources which are associated with different peripherals like ADC, USART, Timers, and so on. Serial communication is the method of transferring data one bit at a time sequentially over a communication channel.
What is the function of accumulator in PIC microcontroller?
To control the internal and external peripherals, control unit is used which are connected to the CPU and the accumulator is used for storing the results and further process. The memory module in the PIC microcontroller architecture consists of RAM (Random Access Memory), ROM (Read Only Memory) and STACK.
