Device Overview

Summary

32-bit AVR microcontroller designed for exceptionally high data throughput with Hi-Speed USB OTG, SD/SDIO card and Multi-Level-Cell (MLC) NAND flash with ECC interfaces. Designed with the multi-layered 32-bit AVR databus, 128 KB on-chip SRAM with triple high speed interfaces,and multi-channel Peripheral and memory to memory DMA controller, the AT32UC3A4256S offers outstanding data throughput.

The device also features a Built-in Hi-Fi stereo Audio DAC, and a full duplex multi-channel I2S audio interface.

The AT32UC3A4256S features an 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 variant.

128KB version: AT32UC3A4128S
64KB version: AT32UC3A464S

144-pin version: AT32UC3A4356S
Non Crypto version: AT32UC3A4256
