Description
The AT90S4434/8535 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 AT90S4434/8535 achieves throughputs approaching 1 MIPS per MHz
allowing the system designer to optimize power consumption versus processing
speed.
