Dear All
please provide me a simple schematics of Philips 89c52 programmer. better if it is serial programmer (DB9) ( I think this is equal to Atmel 89c52 )
your reply is much appreciated.

Dear Li,
Thanks for reply

I sow your attachment but, it is bit unclear if you have simple clear picture. let me see
 

Dear All
please see attached picture and advice me, can I read and write the 89c51/52 using this schematics
Please advice
 

Is it at89c52 or phillips P89v51rd2??
look at this threads and follow down to my post.. : https://www.edaboard.com/threads/237939/

and for your schematics, you can use this, if you have pre programmed microcontroller(8051 written in this picture), this 8051 will program your target microcontroller :

Good Luck

Dear Tushki7
Thank you very much for reply
My MCU is Philips p89c52x2bn
Can I use this schematic for program Philips MCU's?
Please advices
 

Hello
no you cant use this for phillips.. Though you can program at89s51/52 by this programmer...
To program p89 searc for similar threads or google it simple serial programmer circuit...
If you cant find it i will post it for you.

Dear tushki7,
Thank you very much for prompt reply
Can you please post it for me
Thanks again and again
 

Does this at89c52 work in master- slave mode only . I've been trying to program it like at89s52 but it doesn't work at all.

AT89C52 dont have ISP. It can only be programmed with parallel programmer.

Hello,
You cannot use at89s52 programmer to burn at89c51, as at89c52 is older series and it supports parallel programming only.. though at89s52 can be programmed easily and it requires only few pins(MOSI,MISO,SCLK,RESET)..
Here is the circuit for at89C52(Look at attachment Proload 5.4) :
And,
For at89S52 You can use(EZ_ISP Programmer) :

I've replaced the at89c52 with at89s52 but i am facing the same problem in ezdl4 stating try to connect by com1 or com3 ( I've connected by com3).
How to program 89s52 for the first time? Plz reply!

You need a pre-programmed microcontroller(that contains firmare hex file)..
 

I dont have a preprogrammed mcu . I'm just doing my first programming. Can i just program it using UART of the mcu or is it necessary to have a preprogrammed mcu to program another one!

For above programmer circuit, No you cannot program it without using firmware chip..
You need a different Circuit to program it using parallel port of your computer...
Here is the link: **broken link removed**

Or switch to P89v51rd2(they are easy to program).. search the forum for related posts.

Good Luck
