ATtiny25 8-bit Microcontroller With 2/4/8K Bytes In-System Programmable Flash

The ATTINY25 ATTINY45 ATTINY85 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 ATTINY25 ATTINY45 ATTINY85 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
