Description
The AT90S/LS2323 and AT90S/LS2343 is a low-power CMOS 8-bit microcontrollers
based on the AVR
enhanced RISC architecture. By executing powerful instructions
in a single clock cycle, the AT90S/LS2323 and AT90S/LS2343 achieves throughputs
approaching 1 MIPS per MHz allowing the system designer to optimize power con-
sumption 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.
