AT90S4414

Preliminary

Description

The AT90S4414 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 AT90S4414 achieves throughputs approaching 1 MIPS per MHz allowing

the system designer to optimize power consumption versus processing speed.

The AVR core is based on an enhanced RISC architecture that combines a rich

instruction set with 32 general purpose working registers. All the 32 registers are

directly connected to the Arithmetic Logic Unit (ALU), allowing two independent regis-

ters 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.
