We'll tell you all you need to know to start evaluating and working with this product.
The high-performance, low-power 32-bit AVR RISC-based microcontroller combines 512KB flash, 64KB SRAM, 10/100 ethernet MAC, full-speed (12 Mbps) USB 2.0 with embedded host capability, I2S, and a built-in audio D/A converter.
This device features SRAM/SDRAM external bus interface and achieves 91 Dhrystone MIPS (DMIPS) at 66MHz while consuming only 40mA at 3.3V.
The Peripheral Direct Memory Access (PDCA) controller transfers data between peripherals and memories without processor involvement, drastically reducing processing with continuous large data streams within the MCU.
The AT32UC3A0512AU is the Audio version of the AT32UC3A0512. It allows the execution of Atmel licensed Audio firmware IPs.
Two versions are available:
- AT32UC3A0512AU-ALUT: LQFP144, industrial (-40°C to +85°C), tray conditioning.
- AT32UC3A0512AU-ALTRA: LQFP144, automotive (-40°C to +85°C), reel conditioning.
