Designed for high data throughput, low power consumption
and outstanding computing performance, the A0 and A1 Series
features high connectivity with USB On-The-Go, Ethernet MAC
and SDRAM interfaces. These features, combined with a fast
flash and large internal SRAM, make ideally suited for data-
intensive applications.
The A0 and A1 Series are particularly well suited for applications
requiring Ethernet or USB connectivity and high computing
performance. These devices are used in a wide range of
applications including audio, biometric, communication, industrial
control and web servers.

The AVR UC3 A3 and A4 Series are designed for exceptionally
high data throughput with Hi-Speed USB On-The-Go, SD/SDIO
card, Multi-Level-Cell (MLC) NAND flash with ECC and SDRAM
interfaces. With their multi-layered AVR databus, 128 KB on-
chip SRAM with triple high-speed interfaces, and multi-channel
peripheral and memory-to-memory DMA controller, the A3 and
A4 offers outstanding data throughput. They also feature a Hi-Fi
stereo Audio DAC and a full duplex multi-channel I2S audio
interface.
The A3 and A4 Series are available with an optional AES crypto
module capable of 128 to 256-bit AES encryption at speeds of
up to 22.8 MBytes/s. Note that export restrictions apply to this
device variant.
The A3 and A4 Series are particularly well suited for applications requiring Hi-speed USB connectivity,
high computing performance and fast memory interfaces. These devices are used in a wide range of ap-
plications including audio, biometric, communication, USB to SDcard bridges and USB dongles.
