ATTINY28L-4AI

Product Summary

The ATTINY28L-4AI is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATTINY28L-4AI achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed. All the 32 registers are directly connected to the ATTINY28L-4AI Arithmetic Logic Unit (ALU) , allowing two independent registers to be accessed in one single instruction executed in one clock cycle.
