AVR128DA28/32/48/64
Preliminary Data Sheet
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).
AVR-DA Family Overview
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

Note: Marked devices are described in this data sheet.
Devices with different Flash memory sizes typically also have different SRAM.
The name of a device in the AVR-DA family is decoded as follows:
