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 Figure 1. AVR-DA Family Overview Flash 128 KB AVR128DA28 AVR128DA32 AVR128DA48 AVR128DA64 64 KB AVR64DA28 AVR64DA32 AVR64DA48 AVR64DA64 32 KB AVR32DA28 AVR32DA32 AVR32DA48 28 48 32 64 Pins 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:
