The ATMEGA8U2-AU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA8U2 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.Note: These microcontrollers were found in back stock after we had removed them from any current build. We are offering them for a limited time at a severely reduced cost. We will not be stocking the ATMEGA8U2-AU once the current supply is gone.Features:8K Bytes of In-System Programmable Flash with Read-While-Write capabilities512 Bytes EEPROM512 SRAM22 General Purpose I/O32 General Purpose Working Registers2 Flexible Timer/Counters with Compare Modes and PWM1 USARTProgrammable Watchdog Timer with Internal OscillatorSPI Serial PortDebugWIRE interfaceDocuments:Datasheet
