ATTINY48-MU

8位微控制器 -MCU 4KB In-system Flash 12MHz 1.8V-5.5V

Overview ATTINY48-MU

The ATtiny48/88 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 ATtiny48/88 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
