The applets in this chapter demonstrate various example circuits based on the PIC16C84 or PIC16F84 8-bit microcontrollers from Arizona Microchip. Hades provides a complete hardware-software cosimulation environment including system-level components like serial (RS232) communication and text-mode or graphical displays. The simulator performance can reach 500.000 instructions per second, which allows running the simulation at real-time or at near real-time with full interactive control.

We selected the 16C84 microcontroller as the first microprocessor in Hades for several reasons:

  • small and regular instruction set
  • low cost
  • DIP18 package
  • EEPROM/FLASH based, therefore easy (re-) programmable
  • several low-cost DIY programmers available
  • good software support (e.g. MPLAB, picclite)
By now, the 16C84 and 16F84 chips have been replaced by the faster but pin-compatible 16F628 and 16F88 microcontrollers. Please visit the separate 16F628 chapter for additional demos with the 16F628 microcontroller.
