The same year, Atmel introduced the first microcontroller using Flash memory.

In the same year, Atmel introduced the first microcontroller using NOR Flash memory to store firmware.

Larger-scale programmable logic devices were introduced by Atmel, Lattice Semiconductor, and others.

The ELF file format is also used with the Atmel AVR ( 8-bit ), AVR32 and with Texas Instruments MSP430 microcontroller architectures.

* Atmel AVR ( 8-bit ), AVR32 ( 32-bit ), and AT91SAM ( 32-bit )

The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996.

Note that the use of " AVR " in this article generally refers to the 8-bit RISC line of Atmel AVR Microcontrollers.

* Atmel AVR, family of 8-bit microcontrollers

** Modern 8-bit and 16-bit Microcontroller chips, such as Atmel AVR and TI MSP430 chips, support JTAG programming and debugging.

* AVR and ATmega are trade names for a series of general-purpose 8-bit microcontroller chips manufactured by Atmel Corporation.

The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996.

Its products include microcontrollers ( including 8051 derivatives, AT91SAM and AT91CAP ARM-based micros, and its own Atmel AVR and AVR32 architectures ), radio frequency ( RF ) devices, EEPROM and flash memory devices ( including DataFlash-based memory ), and a number of application-specific products.

* DataFlash, Atmel proprietary DataFlash is a low pin-count serial interface flash memory.

Three open-source keyer / keyset designs are available: The pickey a ps / 2 device based on the PIC microcontroller, the spiffchorder a USB device based on the Atmel AVR family of microcontrollers, and the GKOS keypad driver for Linux as well as the Gkos library for the Atmel / Arduino open source board.

: In 2006 Atmel released microcontrollers based on the new, 32-bit, AVR32 architecture.

Atmel Corporation was founded in 1984 and is based in San Jose, CA.

In acquiring QRG, Atmel also inherited an ongoing patent lawsuit that QRG had filed against Apple Inc. in 2005 alleging infringement of one of its charge-transfer based patents in the iPod click-wheel ; the case was later settled.

The widely available European funcard series of blank generic ISO / IEC 7816 smartcards were based upon the Atmel processor series ; there was also a PIC card based on the Microchip Corporation PIC series of processors.

* Microcontrollers with as few as six pins need to use low pin-count substitutes for JTAG, such as BDM, Spy-Bi-Wire, or debugWIRE on the Atmel AVR.

Atmel supplies its devices as standard products, ASICs, or ASSPs depending on the requirements of its customers.

Founded by Hal Philipp in 1996, QRG focused on using standard microcontrollers pre-programmed as touch sensors, including devices sourced from several companies including Atmel.

Atmel announced the sale of its North Tyneside, ( England ) facility ( Fab9 ) on October 8, 2007.

* The SwinSID is hardware emulation of SID on the Atmel AVR processor and real SID player using Atmel AVR processor.

The NanoVM was initially developed to run on the Atmel AVR ATmega8 used in the Asuro Robot.

For example, the AT91CAP from Atmel has a block of logic that can be customized during manufacturer according to user requirements.

* Mentec M1 — Processor upgrade board ; microcode implementation of PDP-11 instruction set by Mentec, using Atmel 0. 35 μm ASIC.

Well known RISC families include DEC Alpha, AMD 29k, ARC, ARM, Atmel AVR, Blackfin, MIPS, PA-RISC, Power ( including PowerPC ), SuperH, and SPARC.

* Atmel AVR used in a variety of products ranging from Xbox handheld controllers to BMW cars.

SPARC International was intended to open the SPARC architecture to make a larger ecosystem for the design, which has been licensed to several manufacturers, including Texas Instruments, Atmel, Cypress Semiconductor, and Fujitsu.

Most notably this technique is used by Atmel AVR microcontrollers, and by others as well.

Due to the large number of bits needed to encode the three registers of a 3-operand instruction, RISC processors using 16-bit instructions are invariably 2-operand machines, such as the Atmel AVR, the TI MSP430, and some versions of the ARM Thumb.

This technique is used in some microcontrollers, including the Atmel AVR.

Examples include, the AVR by Atmel Corp, the PIC by Microchip Technology, Inc. and the ARM Cortex-M3 processor ( not all ARM chips have Harvard architecture ).

All SILabs, some Dallas and a few Atmel devices have single cycle cores.

Current vendors of MCS-51 compatible processors include more than 20 independent manufacturers including Atmel, Infineon Technologies ( formerly Siemens AG ), Maxim Integrated Products ( via its Dallas Semiconductor subsidiary ), NXP ( formerly Philips Semiconductor ), Microchip Technology, Nuvoton ( formerly Winbond ), ST Microelectronics, Silicon Laboratories ( formerly Cygnal ), Texas Instruments, Ramtron International, Silicon Storage Technology, Cypress Semiconductor and Analog Devices.

Companies that are current or former ARM licensees include Advanced Micro Devices, Inc., Alcatel-Lucent, Apple Inc., AppliedMicro, Atmel, Broadcom, Cirrus Logic, CSR_plc, Digital Equipment Corporation, Ember, Energy Micro, Freescale, Intel ( through DEC ), LG, Marvell Technology Group, Microsemi, Microsoft, NEC, Nintendo, Nuvoton, Nvidia, Sony, NXP ( formerly Philips Semiconductor ), Oki, ON Semiconductor, Psion, Qualcomm, Renesas, Research In Motion, Samsung, Sharp, Silicon Labs, ST-Ericsson, STMicroelectronics, Symbios Logic, Texas Instruments, VLSI Technology, Yamaha, Fuzhou Rockchip, and ZiiLABS.

Atmel has been a precursor design center in the ARM7TDMI-based embedded system.

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.

Atmel says that the name AVR is not an acronym and does not stand for anything in particular.
