ATMEGA1284P Microcontroller: Pinout, Datasheet, ATMEGA1284 vs. ATMEGA1284P

The ATMEGA1284P-PU is an 8-bit CMOS microcontroller based on the AVR improved RISC architecture that consumes very little power. The ATMEGA1284P-PU provides throughputs approaching 1MIPS per MHz by executing strong instructions in a single clock cycle, allowing system designers to balance power consumption and processing speed.
