Introduction:

The ATmega328P 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 ATmega328P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Features:

• 32 x 8 General Purpose Working Registers
• Up to 20 MIPS Throughput at 20 MHz
• On-chip 2-cycle Multiplier
• 512/1K/1K/2K Bytes Internal SRAM
• 256/512/512/1K Bytes EEPROM
• Power-on Reset and Programmable Brown-out Detection
• Operating Voltage : 1.8 - 5.5V
• Temperature Range:  -40°C to 85°C
• Speed Grade: 0 - 4 MHz@1.8 - 5.5V, 0 - 10 MHz@2.7 - 5.5.V, 0 - 20 MHz @ 4.5 - 5.5V
