ATTINY44A-SSU

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

8位微控制器 -MCU 1.8V, 20MHz Industrial Temp

Overview ATTINY44A-SSU

ATtiny24A/44A/84A 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/84A achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
