The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 8 KB ISP Flash memory with read-while-write capabilities, 512B EEPROM, 512B SRAM, 22 general purpose I/O lines, 32 general purpose working registers, two flexible timer/counters with compare modes and PWM, USART, programmable watchdog timer with internal oscillator, SPI serial port, debugWIRE interface for on-chip debugging and programming, and five software selectable power saving modes. The device operates between 2.7-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed. https://elecena.pl/product/25764329/atmega8u2-au-mcu-avr-usb-8k-flash-avr-usb16k-flash 2024-04-29 https://elecena.pl/product/25764329/atmega8u2-au-mcu-avr-usb-8k-flash-avr-usb16k-flash 2024-07-14
