Microchip ATMEGA328-AU MCU 8Bit 32KB Flash AVR ATmega Microcontrollers

The ATMEGA328-AU is a high-performance 8-bit AVR RISC-based Microcontroller combines 32kb ISP flash memory with read-while-write capabilities, 1kb 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, 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.
