Features 6-channel 10-bit ADC, USART, SPI, I2C, and three timers (2x8-bit + 1x16-bit). 23 I\/O pins with PDIP-28 through-hole package ideal for prototyping and Arduino-compatible designs. 2.7-5.5V supply with only 1uA power-down current.","working_principle":"The ATmega8A uses the AVR enhanced RISC architecture with 130 instructions, most executing in a single clock cycle. The Harvard architecture separates program memory (Flash) and data memory (SRAM) with separate buses, enabling simultaneous instruction fetch and data access. The 16-bit program counter addresses the 8KB Flash. Peripherals are memory-mapped into the I\/O space and accessed via IN\/OUT instructions or direct addressing. The 10-bit SAR ADC uses successive approximation with auto-triggering from timer compare matches. ISP (In-System Programming) allows Flash and EEPROM programming via the SPI interface without removing the device from the circuit. The A suffix version operates from 2.7-5.5V at 0-16MHz.","pin_description":"
