Atmel, acquired by Microchip in 2016, originally developed the ATxmega family of microcontrollers (MCUs). Microchip now offers ATxmega MCUs, which run up to 32 MHz and deliver a combination of real-time performance, high integration and low power consumption.
AVR XMEGA MCUs include features like 2 Msps pipelined ADC, AES and DES encryption, DMA, Advanced Waveform Extension (AWeX), USB, Configurable Custom Logic, LCD controller, battery backup system and more.
New AVR MCU families include features like the Peripheral Touch Controller (PTC), integrated op amps and level shifters, Configurable Custom Logic (CCL), USB and more.
