What's the difference between AVR and ARM? What distinguishes them? Can AVR use in an ARM? Get all of the answers right here. Let's look at the difference between AVR and ARM and how to tell them apart.
What is an AVR microcontroller?
In 1996, ATMAL corporation released the AVR microcontroller. It is also known as advanced virtual RISC and is based on the RISC instruction set architecture(ISA). AT90S8515 was the first microcontroller in the AVR family. The most common type of controller is the AVR microcontroller, which is also the cheapest. It is used in a variety of robotic applications.
What is an ARM microcontroller?
The Acorn computer organization invented the ARM microcontroller, which is now manufactured by Apple, Nvidia, Qualcomm, Motorola, ST microelectronics, Samsung electronics, and TI, among others. It is a RISC instruction set architecture(ISA) based microcontroller that is also known as an advanced RISC microcontroller. It is the most popular microcontroller, and most industries use it for embedded systems because it has a large of features and is good for producing devices with good looks.
AVR Vs ARM | Difference between AVR and ARM
- AVR is microcontroller refers to advanced virtual RISC, While ARM is microcontroller refers to advanced RISC microcontroller (ARM).
- AVR has a bus width of 8-bit or 32-bit. ARM has a bus width of 32 bits and is also available in 64 bits.
- AVR uses FLSH, SRAM, and EEPROM memory, and ARM uses FLASH, SDRAM, EEPROM, and memory.
- AVR speed is 1 clock per instruction cycle. ARM speed is also 1 clock per instruction cycle.
- AVR uses ART, USART, SPI, I2C communication protocol. Burt ARM uses SPI, CAN, Ethernet, I2S, DSP, SAI, USART, UART communication protocol.
- ARM manufactures is ATMEL company. Whereas ARM manufacturers is apple, Nvidia, Qualcomm, Samsung Electronics and Ti, etc.
- AVR is cheap and effective and AVR provides high-speed operation.
- AVRis family includes tiny, atmega, xmega, and special purpose AVR. While ARM's family includes ARMv4, 5,6,7, and series.
- AVR popular microcontrollers include atmega 8,16,32, and Arduino community. Whereas ARM is a popular microcontroller including LPC2148, ARM cortex-M0 to ARM cortex-M7, etc.
