    Hi,im working up some projects using Atmel's at89s51.
    I had searched at the shop for the programmer(downloader) and found that its too expensive.
    So,i want to do a simple programmer for at89s51 so that i can upload hex file from my laptop to the chip at my home.
    Is there any possible to do a simple circuit as i mentioned above using usb port because im using laptop?
    And i need some simulator for this uc.Can suggest some?

    If you want to download hex code to the 8051 via USB, then i will suggest that you use the Atmel AT89S5131 which is a 8051 derivative. This chip has a USB port and can directly receives hex code via USB from the PC using a free software called the Atmel FLIP.
