Description:

• A low-power, high-performance 8-bit AVR microcontroller, the ATMEGA328P-AU was created by Microchip Technology.
• High Performance AVR Core:
• Executes strong commands in a single clock cycle.
• Throughputs reach 1 MIPS per MHz.
• Balances power usage and processing speed well.
• Memory:
• 32 kB of in-system programmable flash.
• 1024 byte EEPROM.
• 2 kB SRAM.
• The 32 kB bootloader area permits on-chip firmware updates.
• Peripheral features:
• 23 general-purpose I/O lines.
• Two 8-bit timer/counters with prescaler and comparison modes.
• A single 16-bit timer/counter featuring prescaler, compare, and capture modes.
• Six PWM channels with multiple mode support.
• 6-channel, 10-bit ADC.
• Communication Interfaces:
• Supports programmable serial USART.
• SPI Serial Interface (Master/Slave).
• Two-wire Serial Interface (I²C).
• There is no native USB support.
• Power Management:
• Operates between 1.8V and 5.5V.
• There are three operational modes: active, idle, and power down.
• Watchdog timer with an on-chip oscillator.
• Brownout detection and software-programmable power-saving modes.
• Development and Debugging:
• Supports JTAG for on-chip debugging.
• Interruptions can occur both within and externally.
• Real-time counter with a separate oscillator.
• Oscillators and clocks:
• Internally calibrated RC oscillator provides a reliable clock.
• External clock sources can be linked to ensure exact operations.
