Product Summary
The ATMEGA48PA-AU is designed as one kind of low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA48PA-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. Also ATMEGA48PA-AU 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 registers to be accessed in one single instruction executed in one clock cycle.
