AT90S/LS2323/2343

1004D–09/01

Description

The AT90S/LS2323 and AT90S/LS2343 are low-power, CMOS, 8-bit microcontrollers

based on the AVR RISC architecture. By executing powerful instructions in a single

clock cycle, the AT90S2323/2343 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.
