AVR-for beginners!!

HELLO everyone! this is first post on introducion to AVR family..so to start things, first of all I would like to tell you differences between a microcontroller and microprocessors.

—A microprocessor is the heart of computer systems.

—A microcontroller is the heart of an embedded system.

—Most communication, digital entertainment and portable devices, are controlled by either of them.

A designer should know what types of components he needs, ways to reduce production costs and product reliable!!


Now, there are huge variety of microcontrollers! They can be classified as, 

—Memory:

•     FLASH, EEPROM, SRAM….         

— CPU’s:

•  4bit, 8bit, 16bit, 32bit…

•  C.I.S.C., R.I.S.C.

•  Harvard, Von Neumann

•  Clock frequency range.
