A Simulator for P89V51RD2

The Philips’ P89V51RD2 is a 80c51 microcontroller which provides a set of powerful features:

  • Timer/Counter 2
  • PCA (Programmable Counter Array)
  • Watchdog timer

uCsim, the 8051 simulator for SDCC, supports various types of 8051 family and one of them is 89C51R. I think it close to the features of P89V51RD2 microcontroller as mentioned above.

To use, enter this commands:

$s51 -t 89c51r

which prompt you to uCsim command shell. You can view the special modules supported by uCsim by enter this in the uCsim shell:

Although this simulator is based on command line, it is free and powerful for the modern 8051 chips.
