ATTINY828R-MU中文资料爱特梅尔数据手册PDF规格书

Overview

ATtiny828 is a low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny828 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
