AT90S/LS8535

1041H–11/01

Description

The AT90S8535 is a low-power CMOS 8-bit microcontroller based on the AVR RISC

architecture. By executing powerful instructions in a single clock cycle, the AT90S8535

achieves throughputs approaching 1 MIPS per MHz allowing the system designer to

optimize power consumption versus processing speed.
