AVR Microcontrollers

\n\n

AVR is Microchip’s 8-bit microcontroller family, spanning the classic ATmega, the tinyAVR (ATtiny) and the extended ATxmega. AVR devices are simple, efficient and well documented, making them a long-standing choice for embedded control, sensing and maker-style projects.

Key Features

8-bit RISC core with a flat, efficient instruction set
Families: ATmega, ATtiny and ATxmega
Flash from 4 KB to 256 KB, SRAM up to 16 KB
Integrated ADC, USART, SPI and TWI/I2C
Wide 1.8 V to 5.5 V supply range
DIP, TQFP and QFN packages

\n\n

Packages, Temperature & Applications

AVR parts come in through-hole DIP and surface-mount TQFP, QFN and VQFN packages, from 8 to 100 pins, across industrial temperature ranges. Applications include embedded control, sensor interfaces, motor control, consumer electronics and industrial automation.

\n\n

Selection Notes

Choose an ATtiny for the smallest footprint, an ATmega for general control, and an ATxmega for more peripherals and performance. Match flash and SRAM to your firmware, check the package and temperature grade, and confirm the clock speed before finalising.

Popular Part Numbers

ATMEGA328P-AU \u2014 32 KB flash, widely used in Arduino-style boards.
ATMEGA128-16AU \u2014 128 KB flash in a 64-pin TQFP.
ATMEGA2560-16AU \u2014 256 KB flash with 86 I/O lines.
ATXMEGA128A1-AU \u2014 128 KB flash with ADC, DAC and event system.

Design Considerations

ATtiny parts suit the smallest, lowest-cost designs, while ATmega covers general control and ATxmega adds more peripherals and performance. Match flash and SRAM to your firmware size, and check the package and temperature grade. Most AVR parts run from 1.8 V to 5.5 V, which simplifies mixed-voltage designs.

\n\n

Why Choose This Series

AVR’s simple, well-documented architecture and huge ecosystem make it easy to bring up and maintain, and the parts are widely available from multiple sources. For cost-sensitive embedded control, sensing and simple motor control, AVR delivers a proven, low-risk path with predictable timing and a large body of community and vendor example code.
