Microchip AVR and AVR32
Architecture agnostic
Do you know, that IAR’s platform for embedded development is architecture agnostic?
AVR and AVR32
The AVR and AVR32 architectures, developed by Atmel (now part of Microchip Technology), are both popular families of microcontrollers used in embedded systems. These architectures are known for their simplicity, efficiency, and versatility.
AVR is being more suited for simpler, cost-effective designs and AVR32 catering to performance-demanding applications.
The key technology components of the architectures:
The AVR architecture is an 8-bit microcontroller design and is widely used in applications such as consumer electronics, industrial control systems, automotive, and hobbyist projects.
AVR Architecture (8-bit):
- Ideal for low-power, cost-sensitive applications.
- Simple RISC design with 32 general-purpose registers.
- Integrated flash memory, EEPROM, and SRAM.
- USART, SPI, I2C for communication, with ADC and PWM support.
Widely used in hobbyist platforms like Arduino.
AVR32 Architecture (32-bit):
- Targeted at more demanding applications with higher computational needs.
- 32-bit RISC core with out-of-order execution.
- Larger Flash and SRAM, external memory support, and cache.
- Advanced peripherals, including Ethernet, USB, and PWM.
- Suitable for industrial, networking, and multimedia applications.
- Enhanced security features, advanced timers, and real-time capabilities.
