ATMEGA8A-AU
Brand: Microchip
ATMEGA8A-AU is a low-power 8-bit AVR RISC microcontroller from Microchip featuring 8 KB of in-system programmable Flash, 1 KB SRAM, and 512 bytes EEPROM. It delivers up to 16 MIPS at 16 MHz and integrates an 8-channel 10-bit ADC, USART, SPI, and I²C interfaces in a compact 32-pin TQFP package. The device supports five software-selectable power-saving modes and operates from 2.7 V to 5.5 V over -40 °C to +85 °C, making it well-suited for cost-sensitive embedded control, sensor interfacing, and consumer electronics applications.
