Features: Package information
Based on the AVR-enhanced RISC architecture, the ATMEGA1280-16AU has a throughput close to 1 MIPS per MHz, which facilitates the designer to optimize the relationship between power consumption and processing speed. In addition, the ATMEGA1280-16AU includes several selectable power saving modes, such as idle mode, power down mode, standby mode, and extended standby mode, which allows for very fast startup and reduced power consumption at the same time.
The ATMEGA1280-16AU is suitable for applications where the supply voltage is in the range of 2.7 V to 5.5 V. It is specified for operating temperatures from -40°C to 85°C and should ensure that the maximum and minimum temperatures of the application do not exceed this range. The ATMEGA1280-16AU is available in a lead-free, 100-pin, compact TQFP package and is compatible with 2-Wire, SPI, USART and other interfaces.
Where are the 32 registers of the ATMEGA1280-16AU connected to?
All 32 registers are connected directly to the Arithmetic Logic Unit (ALU)
How many registers can the ATMEGA1280-16AU access in one cycle by executing one instruction?
Two independent registers can be accessed
What is the maximum clock frequency of the ATMEGA1280-16AU?
