85 in stock

SKU: IC-ATMEGA32A-PU Category: Brand: .


The Atmel® AVR® ATmega32A 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
ATmega32A achieves throughputs approaching 1 MIPS per MHz allowing the system designer
to optimize power consumption versus processing speed.
