AVR DA Family
Introduction
®
The AVR128DA28/32/48/64 microcontrollers of the AVR DA family are using the AVR CPU with hardware multiplier,
running at up to 24 MHz, with 128 KB of Flash, 16 KB of SRAM, and 512B of EEPROM in 28-, 32-, 48- or 64-pin
®
packages. The AVR DA family uses the latest technologies from Microchip Technology, with a flexible and low-
power architecture including Event System, intelligent analog features, advanced digital peripherals and Peripheral
Touch Controller (PTC).

The figure below shows the AVR DA 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
