SELECTION CONTEXT
Explore the details
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
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.
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 — 32 KB flash, widely used in Arduino-style boards.
- ATMEGA128-16AU — 128 KB flash in a 64-pin TQFP.
- ATMEGA2560-16AU — 256 KB flash with 86 I/O lines.
- ATXMEGA128A1-AU — 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.
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.
