ATMEGA328P-PU

ATMEGA328P-PU is a high-performance low power AVR 8bit microcontroller. It is a low power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.

• 131 powerful Instructions – most single clock cycle execution
• 23 GPIO lines, 32 general purpose working registers, 3 flexible timer/counters with compare modes
• 20MHz frequency, 3KB program memory size, 2KB RAM, 1024bytes data EEPROM
• Internal and external interrupts, USART, an SPI serial port, a 6-channel 10-bit ADC
• Programmable watchdog timer with internal oscillator and five software selectable power saving modes
• Atmel® QTouch® library support
• Operates between 1.8-5.5V
• Industrial temperature range from-40˚C to 85˚C
• Available in 32 pin TQFP package
