4.2.1 Processor
The AT32UC3A3256 flash microcontroller is designed for exceptionally high data
throughput with Hi-Speed USB OTG, SD/ SDIO card, Multi-Level-Cell (MLC) NAND
flash with ECC and SDRAM 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 AT32UC3A3256 offers
outstanding data throughput. The device is reprogrammable through the 10 pin JTAG
connector on the board.
