ATTINY45-20SU

Product Summary

The ATTINY45-20SU is an 8-bit microcontroller with 2/4/8kbytes in-system programmable flash. The ATTINY45-20SU 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 ATTINY45-20SU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
