二、ATMEGA2561-16AU产品概述

1、中文概述

16au ATMEGA2561-16AU是一款高性能、低功耗的8位AVR risc微控制器，结合了256kB ISP闪存、8kB SRAM、4kB EEPROM、86条通用I/O线、32条通用工作寄存器、实时计数器、6条具有比较模式的灵活定时器/计数器、PWM、4个USARTs、面向字节的2线串行接口、8通道10位a /D转换器和一个用于片上调试的JTAG接口。该设备在16MHz下实现16MIPS的吞吐量，工作在4.5到5.5V之间。通过在单个时钟周期内执行强大的指令，该设备实现了接近每MHz 1MIPS的吞吐量，平衡了功耗和处理速度。该装置采用高密度非易失性存储技术制造。片上ISP闪存允许程序存储器通过SPI串行接口，由传统的非易失性存储器程序员，或由在AVR核心上运行的片上引导程序在系统内重新编程。

2、英文概述

　　The ATMEGA2561-16AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 256kB ISP flash memory, 8kB SRAM, 4kB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timers/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 8-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device achieves a throughput of 16MIPS at 16MHz and operates between 4.5 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using high density non-volatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-chip boot program running on the AVR core.
