PIC vs AVR Which Microcontroller to select for your Application

When it involves choosing microcontroller, it is genuinely a puzzling mission as there are numerous microcontrollers to be had inside the marketplace with identical specs. So each parameter turns into crucial in terms of selecting a microcontroller. Here we're evaluating two maximum typically used Microcontroller- PIC Microcontroller and AVR Microcontroller. Here they may be as compared on numerous degrees so one can be helpful in selecting microcontroller to your assignment lifebloombeauty. 

 

Start with Project Requirement

Gather all data about your venture to be began earlier than starting to choose any microcontroller. It is very vital that the information should be amassed as a lot as viable as this will play an critical position in choosing the right microcontroller. futuretechexpert

 

Gather facts of venture inclusive of Size of Project

Number of Peripherals and Sensors Used

Power Requirement

Budget of Project

Interfaces Requirement (like USB, SPI, I2C, UART and so on),

Make a Basic Hardware Block Diagram,)

List down how many GPIO is wanted

Analog to Digital Inputs (ADCs)

PWMs

Select the Right Architecture Needed i.E. (eight-bit, 16-bit, 32-bit)

Recognise Memory Requirement of undertaking (RAM, Flash and many others)

Look on the Featured Parameters

When all the statistics is accumulated, then it's miles a proper time to select the microcontroller. In this article the 2 competing microcontroller emblem PIC and AVR can be compared on type of parameters. Depending upon the want of task to examine the two, observe the following parameters which includes naturalbeautytrends,

 

Frequency: Speed at which the microcontroller will operate

Number of I/O pins : Required ports and pins

RAM: All the variables and arrays declared(DATA) in most MCUs

Flash Memory: Whatever code you write is going here after compiling

Advanced Interfaces: Advanced interfaces including USB, CAN and Ethernet.

Working Voltage: Working voltage of MCU including 5V, three.3V or Low voltage.

Target Connectors: The connectors for ease of circuit layout and size.

The maximum of the parameters are comparable in each PIC and AVR however there are some parameters that really fluctuate when compared.

 

Working Voltage

With extra battery operated merchandise, the PIC and AVR have managed to enhance for the low-voltage operations. AVR are higher recognized for low-voltage operation than the older PIC collection such as PIC16F and PIC18F due to the fact those PIC collection used chip-erased technique that want as a minimum four.5V to perform, and beneath 4.5V PIC programmers ought to use row-erase algorithm which can't erase locked device. However this isn't always the case in AVR techsmartinfo.

 

AVR has progressed and released the latest P (percent-strength) variants inclusive of ATmega328P which might be extremely low-electricity. Also the present day ATtiny1634 has improved and is derived with sleep modes to reduce electricity intake when brownout is used which may be very useful in battery powered gadgets smarttechpros.

 

The conclusion is that AVR have been centered on low-voltage previously but PIC now has been transformed for the low-voltage operation and has launched a few products primarily based on picPower.

 

Target Connectors

Target connectors are very essential in terms of layout and improvement. AVR has defined 6 and 10-way ISP interfaces, which makes it easy to use while PIC doesn’t have it, so PIC programmers comes with flying leads or RJ11 sockets which are tough to suit in the circuit.  techgeeksblogger

 

Conclusion is that the AVR has made it easy in phrases of circuit design and development with the target connectors whereas PIC nevertheless wishes to rectify this.
