ATMEGA88PB-AU

8位微控制器 -MCU 8KB 512B 1KB 20 MHZ TQFP GRN

Introduction ATMEGA88PB-AU

ATmega48PB/88PB/168PB 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 ATmega48PB/88PB/ 168PB achieves throughputs approaching 1MIPS/MHz, allowing the system designer to optimize power consumption versus processing speed.
