AVR64EA28/32/48

Preliminary Data Sheet

Introduction

The AVR64EA28/32/48 microcontrollers of the AVR EA Family are using the AVR CPU with hardware multiplier

running at clock speeds up to 20 MHz. They come with 64 KB of Flash, 6 KB of SRAM, and 512 bytes of

EEPROM. The microcontrollers are available in 28-, 32- and 48- pin packages. The AVR EA Family uses the latest

technologies from Microchip with a flexible and low-power architecture, including Event System, accurate analog

subsystems, and advanced digital peripherals.

Family Overview

The figure below shows the AVR EA 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
