The ATMEGA16-16PU from Atmel is a classic 8-bit AVR MCU with 16KB flash and 1KB SRAM. It runs at 16MHz with 4.5-5.5V supply. Features include BOD, POR, PWM, and WDT. The 40-pin DIP package is perfect for through-hole prototyping and industrial control.

  • 40-pin DIP – easy to solder and replace in legacy systems.
  • 5V operation – compatible with TTL logic and industrial sensors.
  • 16KB flash – ample for complex control algorithms.
  • Mature AVR ecosystem – extensive libraries and community support.
