Since then support for AVR32 has been dropped from Linux as of kernel 4.12 compiler support for the architecture in GCC was never mainlined into the compiler's central source-code repository and was available primarily in a vendor-supported fork. The instruction set was similar to other RISC cores, but it was not compatible with the original AVR (nor any of the various ARM cores). It had a 32-bit data path, SIMD and DSP instructions, along with other audio- and video-processing features. This was a completely different architecture unrelated to the 8-bit AVR, intended to compete with the ARM-based processors. In 2006, Atmel released microcontrollers based on the 32-bit AVR32 architecture.SRAM for the AVR program code, unlike all other AVRs.megaAVRs with special features not found on the other members of the AVR family, such as LCD controller, USB controller, advanced PWM, CAN, etc.Extended performance features, such as DMA, "Event System", and cryptography support.

The ATxmega series offers a wide variety of peripherals and functionality such as: AVR EA-series (not yet released as of September 2021).AVR DD-series (not yet released as of September 2021) – small package microcontrollers designed to bring real-time control and multi-voltage operation to applications industrial control, home appliance products, automotive, and Internet of Things (IoT).AVR DB-series (mid-late 2020) – inherits many features from the DA-family, while adding its own:.offers the latest CIPs and a robust integrated analog portfolio.integrated sensors for capacitative touch measurement ( HCI).AVR DA-series (early 2020) – The high memory density makes these MCUs well suited for both wired and wireless communication-stack-intensive functions.an Async Type D timer that can run fast than CPU.The parts numbers is formatted as AVR ffD xpp, where ff is flash size, x is family, and pp is number of pins.Įxample: AVR128DA64 – 64-pin DA-series with 128k flash New peripherals with enhanced functionalityĪVR Dx – The AVR Dx family is featuring multiple microcontroller series, focused on HCI, analog signal conditioning and functional safety.Extended instruction set (multiply instructions and instructions for handling larger program memories).The ATmega series features a microcontroller that provides a solid amount of program memory, as well as a wide range of pins available. Improved AVRxt instruction set, hardware multiply.
The designers worked closely with compiler writers at IAR Systems to ensure that the AVR instruction set provided efficient compilation of high-level languages. When the technology was sold to Atmel from Nordic VLSI, the internal architecture was further developed by Bogen and Wollan at Atmel Norway, a subsidiary of Atmel. It was known as a μRISC (Micro RISC) and was available as silicon IP/building block from Nordic VLSI. The original AVR MCU was developed at a local ASIC house in Trondheim, Norway, called Nordic VLSI at the time, now Nordic Semiconductor, where Bogen and Wollan were working as students. Note that the use of "AVR" in this article generally refers to the 8-bit RISC line of Atmel AVR microcontrollers.
However, it is commonly accepted that AVR stands for Alf and Vegard's RISC processor. The creators of the AVR give no definitive answer as to what the term "AVR" stands for.
Ītmel says that the name AVR is not an acronym and does not stand for anything in particular. The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH), Alf-Egil Bogen and Vegard Wollan.
