The AT32UC3A3 32-bit AVR microcontroller yields 91 DMIPS at 66 MHz and has a Hi-Speed 480-Mbit/s USB OTG interface, dual SD/MMC card interfaces, up to 256 Kbytes of flash, and 128 Kbytes of RAM. The chip’s advanced DMA offloads CPU data transfer.
The 144-pin TBGA- and LQFP-packaged IC offers DSP instructions that remove the need for custom audio decoder hardware. It offers an integrated stereo 16-bit bitstream DAC, a NAND flash controller, and a 10-bit A/D converter. The device consumes less than 2 mW/MHz in active mode. ($4.41 ea/10,000 — available now.)
