AVR-urile sunt microcontrollere tipice de la ATMEL

http://www.atmel.com/products/AVR/overview.asp

"The AVR 8-Bit RISC microcontroller from Atmel is a very common microcontroller. This microcontroller is one chip with EEPROM, Ram, Analog to Digital converter, a lot of digital input and output lines, timers, UART for RS 232 communication and many other things."

"AVR Microcontrollers

The AVRs are 8-bit RISC platforms with a Harvard architecture (program and data memory are separate). Figure 1 details the ATtiny26 AVR chip internal organization. Like each member of a family, it has its own particular combination of I/O and peripherals, but it shares a basic architecture and instruction set with all the other AVRs."

"A number of factors make the AVR microcontrollers a good choice, especially for beginners. AVRs are:

Easy to code for: AVRs were designed from the ground up to allow easy and efficient programming in high-level languages, with a particular focus on C.

Easy to program: the combination of onboard reprogrammable Flash program memory and the in-system programming interface keeps the process of transferring software to the microcontroller simple and cheap.

Powerful and inexpensive: AVRs pack a lot of power (1 MIPS/MHz, clocks up to 16MHz) and space (up to 128K of Flash program memory and 4K of EEPROM and SRAM) at low prices. Most AVRs even include additional peripherals, such as UARTs and analog-to-digital converters.

Hobbyist-friendly: most of the chips in the AVR family come in easy-to-use 8-, 20-, 28- or 40-pin dual in-line packages (DIPs) and can be ordered in unit quantities from a number of distributors."

AMR-urile sunt microcontrollere de la AM Research, dacă la asta te referi:
