• ATmega8A-PU Atmel Microchip MCU | 8KB Flash, 28-Pin DIP

ATmega8A‑PU – 8 KB Flash, 28‑Pin DIP Microcontroller
The ATmega8A‑PU is a low‑power, high‑performance 8‑bit AVR microcontroller from Microchip (formerly Atmel) packaged in a classic 28‑pin DIP. Ideal for hobbyist labs, introductory embedded‑systems courses, and rapid‑prototyping projects, it combines a robust instruction set with a generous 8 KB of self‑programming Flash, 1 KB EEPROM and 512 B SRAM—all accessible through familiar Arduino‑compatible pins. Its built‑in peripherals—timers, ADC, UART, SPI, and I²C—let students move from blinking LEDs to fully‑featured sensor nodes without swapping hardware.

What students will learn: programming in C/Assembly for real‑world hardware, configuring I/O ports, using on‑chip peripherals, implementing interrupt‑driven designs, and mastering low‑power modes for battery‑operated devices. By wiring the DIP into a breadboard and debugging with an AVR‑ISP programmer, learners gain hands‑on experience with the complete development cycle—from code compilation to in‑circuit testing.

Key features

• 8 KB In‑system programmable Flash, 1 KB EEPROM, 512 B SRAM
• 28‑pin DIP package – easy to prototype on a breadboard
• 32 general‑purpose I/O pins, 6 PWM channels, 8‑channel 10‑bit ADC
• Three 8‑bit timers/counters, UART, SPI, I²C (TWI) interfaces
• Low‑power sleep modes (down to 0.1 µA) for energy‑aware projects
• Robust bootloader support for Arduino‑style development

Why it’s great: The ATmega8A‑PU offers the perfect balance of simplicity and capability, making it a go‑to teaching tool for anyone starting with embedded systems. Its DIP form factor eliminates soldering headaches, while the extensive AVR ecosystem—IDE, libraries, and community tutorials—means students can focus on learning concepts rather than fighting hardware quirks. Whether building a line‑follower robot, a weather station, or a custom keypad, this microcontroller delivers reliable performance at an unbeatable price point.
