    I found a code Downloader for a ATMEL 89C2051, but I have 2 microcontrolers 8051 and 8031 to work on.
    Can I use this device for both?

    Thanks in Advance.
    :shock:

    89C2051 has the same core as that of 8051/8031. The only differenece is that it has 2kB of FLASH ROM and has only 20 pins. Rest everything is same. You can use it in place of 8051/31 provided that your code does not use port pins which it does not have.

    Standard 8051 - 4k EPROM/OTPROM
    Standard 8031 - ROMLESS
