Overview
ATA6602/ATA6603
Block Diagram
Block Diagram
The ATA6602/ATA6603 uses a low-power CMOS 8-bit microcontroller based on the AVR
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
ATA6602/ATA6603 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
