The AT90S8515 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 AT90S8515 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 regis-
ters. 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.
