Atmel ATmega328-P U 28 Pin Dip Microcontroller

The ATmega328-P U 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 ATmega328-PU achieves through puts approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Advanced RISC Architecture:

• 131 Powerful Instructions
• Most Single Clock Cycle Execution
• 32 x 8 General Purpose Working Registers
• Fully Static Operation
• Up to 20 MIPS Throughput at 20 MHz
• On-chip 2-cycle Multiplier

• Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode
• One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode
• Real Time Counter with Separate Oscillator
• Six PWM Channels
• 8-channel 10-bit ADC in TQFP and QFN/MLF package Temperature Measurement
• 6-channel 10-bit ADC in PDIP Package Temperature Measurement
• Programmable Serial USART
• Master/Slave SPI Serial Interface
• Byte-oriented 2-wire Serial Interface (Philips I2 C compatible)
• Programmable Watchdog Timer with Separate On-chip Oscillator
• On-chip Analog Comparator
• Interrupt and Wake-up on Pin Change
