The ATmega8A is a high-performance, low-power 8-bit microcontroller based on the AVR RISC architecture. It features 8 KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 1 KB of SRAM, supporting a variety of applications. The microcontroller can execute up to 16 million instructions per second (MIPS) at a clock speed of 16 MHz, optimizing power consumption while maintaining processing speed. The ATmega8A includes multiple peripheral features such as two 8-bit timers, one 16-bit timer, a real-time counter, and a programmable watchdog timer. It also offers an 8-channel 10-bit ADC in TQFP and QFN/MLF packages, along with serial communication interfaces including USART and SPI. The device operates within a voltage range of 2.7V to 5.5V and supports five sleep modes for energy efficiency. With 23 programmable I/O lines and various built-in safety features like power-on reset and brown-out detection, the ATmega8A is suitable for a wide range of embedded applications. Its robust memory and processing capabilities make it a viable choice for engineers looking for a reliable microcontroller for their projects.
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, 1 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented Two-Wire serial interface, 6-channel 10-bit A/D converter (8-channel in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, SPI serial port, 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.
