Hot sale original electronics ATMEGA256016U-TH 8-bit Microcontroller with 64K/128K/256K Bytes In-System Programmable Flash

Product Details

Overview

The ATmega640/1280/1281/2560/2561 is a low-power CMOS 8-bit microcontroller

 based on the AVR enhanced RISC architecture. 

By executing powerful instructions in a single cloc k cycle, 

the ATmega640/1280/1281/2560/2561 achieves throughputs approaching 1 MIPS 

per MHz allowing the system designer to optimize power consumption

 versus processing speed.
