AVR64DD32/28 8-Bit Multi-Voltage I/O MCUs

Microchip Technology AVR64DD32/28 8-Bit Multi-Voltage I/O MCUs are based on the AVR® CPU with a hardware multiplier running at clock speeds up to 24MHz across the full supply voltage range of 1.8V to 5.5V. The family includes 16KB, 32KB, and 64KB Flash variants in 14- to 32-pin package options (TQFP and VQFN). The AVR® DD family is designed to bring real-time control and multi-voltage operation to applications, including industrial control, home appliance products, automotive, and the Internet of Things (IoT).
