Introduction:
Welcome to the world of Microcontrollers, and the first thing you need is a Device Programmer. This In System Programmer is RS232 (serial port) based but can indirectly be used with USB using USB to RS232 converter. If you need something like this you need to assemble a very simple circuit (Programmer Unit).
Hardware:
Figure 1 shows the Block diagram of the in-system programmer interface, the programmer can be self powered or target powered it depends on how you plan to use it.
Figure 2 shows the actual circuit diagram. The Programmer has just two ICs. IC1 = AT89C2051, IC2 = MAX 232. Few Resistors, LEDs, capacitors etc. The value of the crystal is critical and must be 11.0592 MHz.
Firmware:
Assemble the circuit and burn the firmware into an AT89C2051(you will need a conventional parallel Programmer to Program the AT89C2051).
Software:
The Software is a Windows GUI application and supports all programming functions. When you run the software for the first time it looks for a valid programmer on COM1. If the Programmer is connected to say COM2 you will receive an error message but when the application starts select Options->Settings on the Menu and specify the correct COM Port.
Following are the main features of this software,
- Device Supported – AT89S51, AT89S52, AT89S8252, AT89S8253.
- Read and write Intel Hex files.
- Chip Erase.
- Verify.
- Lock.
- Read Device Signature.
- Advanced Device Specific Functions.

good morning
is it works bi directional mean USB to serial..?
how can i burn firmware in at89c2051. plz help
who can burn the firmwere in 89c51
who can burn the firmwere in 89c51. Plz help me sir plzZZZ
kindlysome one tell me about the same kind of programmer i mean isp programmer for PIC24hj128gp502. thanxxx
who can burn firmware in 89c53
plzzzzzz…..help
i am a E.E.E student so iam vary like projet works
its good project i made it thanks
HI
I WANT TO MAKE THIS PROGRAMMER, I AM STUCK ON USB TO DB-9 CONVERTER, I WANT TO MAKE MY OWN CONVERTER. SINCE USB HAS FOLLOWING PINOUTS
1) VCC
2)DATA-
3)DATA+
4)GROUND
AND DB-9
2) RX
3)TX
5)GROUND
I WANT HELP WITH VCC OF USB. DO I NEED TO CONNECT IT? IF YES THAN HOW?
HI
I HAVE RESOLVED VCC ISSUE BUT I AM UNABLE TO BURN THE HEX FILE IN AT89C2051, IT GIVES ME AN ERROR.
HI
I want to ask that when I tried to burn the HEX file named “FirmWare v1.4.HEX” using “DATAMAN PRO” which is a Universal Programmer. It gave me an error. It is possible that the file might be corrupted because I unzip the file and I have only saved the HEX file in usb. it is matter?
If no than the file might be corrupted so is there any other way to disassembles the hex file because I found many disassembles but unable to convert to “.Asm” format properly.
I will thankful to you if you would kindly help me out in this.
Thankyou
sir, I successfully burnt the at89c2051 ic, and the hex file programming into the at89s52 is giving an error, it is not reading the signature even, not programming what to do? please help me somebody
Sir I burnt at89c2051 firmware in ic successfully.When I run software it gives error msgs “RECEPTION ERROR” & “NO SUPPORTED PROGRAMMER DETECTED”. Plz help me
