USB AVR microcontroller downloader-programmer
Also can program AT89S51/52 (S-series) using USB port
Also can program serial EEPROM (AT24c01,02,04,06,...512)
firmware included

The building AVR microcontroller project now easily by wizard program like codevision AVR then burning firmware into microcontroller using AVR downloader like this (figure 1). Very simple and USB support. Your old microcontroller example AT89S51 (S-series) can program trough this circuit via USB port. For AT89S5x (S-series) the important thing is pin SCK, MISO, MOSI, etc (see figure below... X2) properly connected to the IC ISP (mosi, miso, sck, etc). This circuit also can program serial eeprom like AT24C24, AT24c64, and other..... (using this PC interface)

NOTES FOR ACCEPT AT89S series
1. PROGISP172 firmware-> USB51/main.hex when burning firmware to ATmega8, set fuse bit Low Fuse=EF, High Fuse=C9 also use this Circuit
2. Reset Circuit for AT89S (S-series), the Capacitor (Elco) must be 1uF NOT 10uF, so use 1uF/16V and the Resistor usually 10K ohm
