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.

Since its inception 30 years ago, Atmel® has provided innovations in the essential building blocks of IoT designs—from embedded processing and connectivity to sensors, security, and software.

8-bit AVR microcontrollers (MCUs) offer unsurpassed performance, power efficiency and flexibility with the industry's most code-efficient architecture.

The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.

ATmega MCUs offer substantial program and data memories with performance up to 20 MIPS. With innovative picoPower ® technology that minimizes power consumption, all ATmega MCUs offer self-programmability for fast, secure and cost-effective in-circuit upgrades. You can even upgrade the flash memory while running your application.
