AVR® DB 8-Bit Microcontrollers

Microchip Technology AVR® DB 8-Bit Microcontrollers are designed to bring analog signal conditioning, real-time control, and multi-voltage operation to applications including industrial control, home appliances, and Internet of Things (IoT). The AVR DB MCUs operate at up to 24MHz across the full supply voltage range of 1.8V to 5.5V. These devices include 32KB, 64KB, and 128KB Flash variants in 28- to 64-pin package options.
