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.
