ATTINY48-AU

Product Summary

The ATTINY48-AU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions ina single clock cycle, the ATTINY48-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-sumption versus processing speed.
