Offering a hardware and firmware solution that simplifies the task of designing high-quality digital audio equipment, the AT32UC3xxxxx controller is a tailored version of the low power UC3 32-bit processor. The chips firmware IP includes control and streaming interfaces for a selection of popular smart-phones and portable media players as well as MP3, WMA and AAC decoders to allow designers to decode compressed music files and USB protocol stacks.
AVR UC3 microcontrollers also support the QTouch® Library for easy implementation of elegant, differentiating user interfaces for capacitive touch. The AT32UC3A0512 version combines 512 Kbytes of flash, 64 Kbytes of SRAM, a 10/100 Ethernet MAC, full-speed USB 2.0 host, I2S, and an audio D/A converter. The device has a SRAM/SDRAM external bus interface and achieves 91 DMIPS at 66 MHz while taking just 40 mA at 3.3 V. Othe version include a floating point unit, FlashVault code protection, CAN interfaces, LIN interfaces, and PWM with dead-time insertion, A/D conversion. (11 versions from $5.02 to $10.37 ea/10,000 available now.)
