MCU & Digital

Microcontrollers are known as ideal and cost-optimized solutions for all applications with digital and analog inputs and outputs. Even instead of state machines, these microcontrollers can be used as a real alternative.They offer the user much greater flexibility for the same price.The integrated watchdog and the low-voltage reset also ensure operational safety, as do the integrated protective diodes on all inputs and outputs.The available development environment enables easy entry due to its handling and the price structure.

Karl Kruse offers a wide range of Microcontroller such as:

  • 8-BIT Microcontroller
  • 32-BIT Microcontroller
