The AT90S2313 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 AT90S2313 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.
