Description
The AT90S4434/8535 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing pow-
erful instructions in a single clock cycle, the AT90S4434/8535 achieves throughputs approaching 1 MIPS per MHz allowing
the system designer to optimize power consumption versus processing speed.
