Which processors are typically used for microcontrollers?
Types
- ARM core processors (many vendors)
- Microchip Technology Atmel AVR (8-bit), AVR32 (32-bit), and AT91SAM (32-bit)
- Cypress Semiconductor’s M8C core used in their PSoC (Programmable System-on-Chip)
- Freescale ColdFire (32-bit) and S08 (8-bit)
- Freescale 68HC11 (8-bit), and others based on the Motorola 6800 family.
What is AVR in microprocessor?
AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.
What are the examples of microprocessor?
Table: Important Intel Microprocessors

What is microcontroller and microprocessor?
Microprocessor consists of only a Central Processing Unit, whereas Micro Controller contains a CPU, Memory, I/O all integrated into one chip. The microprocessor uses an external bus to interface to RAM, ROM, and other peripherals, on the other hand, Microcontroller uses an internal controlling bus.
What is avavr microcontroller?
AVR Microcontroller: AVR microcontroller is an electronic chip manufactured by Atmel, which has several advantages over other types of microcontroller. We can understand microcontroller by comparing it with Personal Computer (PC), which has a motherboard inside it.
What is internal EEPROM in AVR microcontroller?
Almost all AVR microcontrollers have internal EEPROM for semi-permanent data storage. Like flash memory, EEPROM can maintain its contents when electrical power is removed. In most variants of the AVR architecture, this internal EEPROM memory is not mapped into the MCU’s addressable memory space.
What is Atmel AVR?
The AVR is a type of MCUs which is created by the Atmel this controller provides numerous features that are lacking in other types of MCUs. This microcontroller is like our personal computer which has different types of elements such as EEPROM, RAM, microprocessor, all these and some other components are exits on this board.
