AT32UC3A464

Part Description

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 AT32UC3A464S 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 AT32UC3A464S 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. 256KB version: AT32UC3A4256S 128KB version: AT32UC3A4128S 144-pin version: AT32UC3A364S Non crypto version: AT32UC3A464
