• 4KB version: ATtiny44A
• 2KB version: ATtiny24A

ATtiny24A/44A are low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC
architecture. By executing powerful instructions in a single clock cycle, the ATtiny24A/44A
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
