描述 Description

A complete system-on-chip 32-bit AVR microcontroller. It is designed for cost-sensitive embedded applications that require low power consumption, high code density and high performance. The microcontroller's Memory Protection Unit (MPU) and fast, flexible interrupt controller support the latest real-time operating systems. Higher computation capabilities are achievable using a rich set of DSP instructions. The device incorporates on-chip flash and SRAM memories for secure and fast access. 64 KBytes of SRAM are directly coupled to the AVR32 UC for performance optimization. Two blocks of 32 Kbytes SRAM are independently attached to the high speed bus matrix for real ping-pong management.The microcontroller achieves exceptionally high data throughput by combining the multi-layered 32-bit AVR databus,128 KB on-chip SRAM with triple high speed interfaces, multi-channel peripheral, memory-to-memory DMA controller, high-speed USB embedded host, SD/SDIO card, MLC NAND flash with ECC, and SDRAM interfaces.This device features 128KB internal high-speed flash and an AES crypto module, capable of 128 to 256-bit AES encryption at speeds of up to 22.8MBytes.
