ATTINY44-20MU

AVR, 4KB FLASH, 256B EE AND SRAM - 5V, 20MHz, MLF, IND TEMP, GREEN

Overview

The ATtiny24/44/84 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 ATtiny24/44/84 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
