AVR64DU in AVR DA/DB/DD/DU Family
The AVR64DU family, developed by Microchip Technology, represents the latest generation of 8-bit AVR microcontrollers featuring integrated Full-Speed USB 2.0 connectivity. Operating at up to 24MHz, these MCUs leverage the AVR core with Core Independent Peripherals (CIPs) to offload tasks from the CPU. This sub-family is specifically designed for applications requiring reliable USB communication without external crystal oscillators, while maintaining the low power consumption and robust signal conditioning characteristics typical of the modern AVR DA/DB/DD lineages.
Variants in This Sub-Family
Variants within the AVR64DU sub-family are primarily distinguished by their physical packaging and pin counts, ranging from 20-pin to 32-pin options such as VQFN and TQFP. While core specifications like the 64KB Flash and 8KB SRAM remain consistent across the 64DU series, the number of available GPIO pins and multiplexed ADC channels vary. Temperature ratings also differ between industrial-grade and extended-range variants to suit specific environmental requirements.
