AT32UC3A1512-AUT Part Information
Details for AT32UC3A1512-AUT by Microchip Technology
AT32UC3A1512
Part Description
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. The MCU achieves 91 Dhrystone MIPS (DMIPS) at 66 MHz while consuming only 40 mA 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.
