The high-performance, low-power 32-bit AVR RISC-based microcontroller combines 128KB flash, 32KB 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.
