AVR64DD32/28
AVR® DD Family
Introduction
The AVR64DD32/28 microcontrollers of the AVR® DD Family of microcontrollers are using the AVR® CPU with
hardware multiplier running at clock speeds up to 24 MHz, with 64 KB of Flash, 8 KB of SRAM, and 256 bytes
of EEPROM. The microcontrollers are available in 28-or 32-pin packages. The AVR DD Family uses the latest
technologies from Microchip Technology, with a flexible and low-power architecture, including the Event System,
intelligent analog features, and advanced digital peripherals. AVR® DD Family Overview
The figure below shows the AVR DD Family devices, laying out pin count variants and memory sizes:
•
• Vertical migration is possible without code modification, as these devices are fully pin and feature compatible
Horizontal migration to the left reduces the pin count and, therefore, the available features Figure 1. AVR® DD Family Overview
