Atmel ARM-based processors are microcontrollers and microprocessors integrated circuits, by Microchip Technology (previously Atmel), that are based on various 32-bit ARM processor cores, with in-house designed peripherals and tool support.

Atmel Corporation was a creator and manufacturer of semiconductors before being subsumed by Microchip Technology in 2016. Atmel was founded in 1984. The company focused on embedded systems built around microcontrollers.

Atmel Corporation was a worldwide leader in the design and manufacture of microcontrollers (MCUs), capacitive touch solutions, advanced logic, mixed-signal, nonvolatile memory and Radio Frequency (RF) components.

Atmel offers a wide range of solutions for CAN networking, including AVR 8-bit RISC microcontrollers and transceivers ready to go with data-rates up to 5Mbit/s supporting the new CAN Flexible Data-rate standard (CAN FD).

atmel是少数几个能够将高性能、高精度的模拟模块（特别是 adc 和 dac ）集成到数字asic之内的半导体生产商。此外，atmel还可以为 空间应用 提供一系列的防辐射asic产品。

Atmel AT18F 系列由简便易用的配置编程软件 (CPS) 支持，推荐用于新的 FPGA 设计。Atmel 的小外形尺寸封装符合 ROHS 标准，减少了对电路板空间的占用，同时为流行的、基于 FPGA 的系统提供系统级“drop in”解决方案，从而加快了产品面市时间。

AVR单片机是1997年由ATMEL公司研发出的增强型内置Flash的RISC(Reduced Instruction Set CPU) 精简指令集高速8位单片机。 可以广泛应用于计算机外部设备、工业实时控制、仪器仪表、通讯设备、家用电器等各个领域。
