Overview
Block Diagram
2502KS–AVR–10/06
The ATmega8535 is a low-power CMOS 8-bit microcontroller based on the AVR
enhanced RISC architecture. By executing instructions in a single clock cycle, the
ATmega8535 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
