Microchip AVR Microcontrollers Overview

BeiLuo supplies genuine Microchip AVR microcontrollers, the 8-bit single-cycle RISC family that became famous for its efficiency and its wide use in embedded designs. The AVR core executes most instructions in a single clock cycle and reaches about one MIPS per MHz, so it balances a good performance with a low power and a low cost, and the 32 general-purpose registers and the rich instruction set make the code compact and fast. The family spans the tiny ATtiny parts in an 8-pin package for a simple sensor or a control task, the mainstream ATmega328P in a 28-pin package for a general application, and the large ATmega2560 with 256 KB of flash and 86 general-purpose I/O for a complex design, all sharing the same toolchain and a large community of code and examples. The devices include in-system programmable flash, EEPROM and SRAM, a set of timers with PWM, an analog-to-digital converter and interfaces such as USART, SPI and I2C, and they operate over a broad voltage range. Typical applications include consumer products, hobby and education projects, sensor nodes, motor control and industrial control. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the memory and the package and plan the software and the peripherals.

Which AVR part should I choose?

Choose the ATtiny85 for a small, low-cost task in an 8-pin package, the ATmega328P for a general application with a good balance of memory and I/O, and the ATmega2560 for a large design that needs 256 KB of flash and many I/O lines.

Our FAE team can help match the part.

Why is the AVR core efficient?

The AVR core executes most instructions in a single clock cycle and has 32 general-purpose registers, so it reaches about one MIPS per MHz and keeps the code compact. This is why it has been popular for so long in embedded designs.
