ATMEGA328P-MU AVR 8-bit Microcontrollers - MCU 32KB In-system: Datasheet, Pinout, and Equivalents

The ATMEGA328P-MU is a high-performance picoPower  8bit AVR RISC  -based microcontroller that combines 32kb ISP  flash memory with read-while-write capabilities, 1024B EEPROM, 23 general-purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI  serial port, a 6-channel 10-bit A/D converter  (8-channels in TQFP  and QFN  /MLF packages), programmable watchdog timer with internal oscillator and five software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
