ATMEGA8L 8A 8PU DIP 28 Pin
The ATmega8L-8PU is a low-power 8-bit AVR microcontroller built with RISC architecture, delivering robust performance in compact, efficient design. Packaged in a DIP-28 form factor, it allows easy integration into breadboards and prototyping PCBs.
With 8KB of Flash memory, 1KB SRAM, and 512 bytes EEPROM, this MCU offers ample storage for logic, sensor data, and configuration parameters. It operates at 2.7V–5.5V, supporting applications where low voltage operation and power efficiency are essential. Clocked at a maximum of 8 MHz, it’s a reliable controller for a variety of embedded systems.
Its 23 general-purpose I/O pins, integrated ADC, USART, SPI, and TWI (I²C) interfaces make it ideal for projects requiring multiple sensor or module connections — all in a lightweight, low-power package.
