Description:

• AVR RISC-based 8-bit high-performance, low-power microcontroller, the ATMEGA8U2-AU was created by Microchip Technology.
• High Performance AVR Core:
• Performs strong commands in a single clock cycle.
• Throughput approaches 1 MIPS (Million Instructions Per Second) per MHz.
• Balances power usage and processing speed well.
• Memory:
• 8 kB of in-system programmable flash.
• 512 byte EEPROM.
• 512 bytes of SRAM.
• An 8 kB bootloader allows for speedy and secure updates.
• Peripheral features:
• USB 2.0 full- and low-speed device with six terminals.
• Serial USART is programmable.
• SPI serial interface (master/slave).
• Twelve programmable I/O lines allow for a wide range of applications.
• Robust Development and Debugging.
• JTAG interface allows for on-chip debugging.
• Interruptions can occur both within and externally.
• True Read-While-Writing capabilities.
• Oscillators and Timer:
• Three configurable 8-bit timers/counters with comparison modes.
• One 16-bit timer/counter with compare and capture modes.
• Real-time counter with a separate oscillator.
• Power Management:
• Operates between 2.7V and 5.5V.
• There are three types of waiting modes: active, idle, and powered down.
• Communication Interfaces:
• USB, UART, SPI, and I2C protocols are all supported.
