Dear TechiEE12, I am currently working on a schematic design involving the Atmel AT89S52 Microcontroller along with several ports. As part of the design, I am looking to program the microcontroller to make an LED connected to Port P1.1 blink for 5 seconds ON and 5 seconds OFF. Given that this is a basic example, I plan to extend my design to include a 16-bit microcontroller along with other components like GPRS, ADC, DAC, etc. However, I am aware that the behavior of programmable devices, such as microcontrollers, is dependent on the code uploaded to them, typically written in Assembly Language or Embedded C. As such, I believe there may not be static SPICE models available for such programmable devices, but I would appreciate your confirmation or correction on this matter. Additionally, I have noticed that OrCAD PSpice Designer includes a feature called the DMI (Device Model Interface) template. Could you kindly clarify whether this feature can assist in simulating the behavior of programmable devices, or if there are alternative methods to achieve this in PSpice? I look forward to your insights. Best regards, Rohit
