Get a programmer for 8051

[Majmun]

Hi all. I have AT89C51RB2-UM and 2 AT89C51-24PI microcontroller. Is it posible to program them without buying original programmer? I dont wont to spend money just to programmer this 3 uC. Is there a way so I can build my on programmer?

u can build your own programmer. but again it requires programmed micro-controller chip. so how will you program that chip?

the NXP mircor controller like P89V51RD2 can be serially programmed using flash magic software no need of any external programmer. so it is the best option

[Majmun]

ok. but do you have schematics? 

[Ashutosh Bhatt]

you will get schematic from flash magic website. or just search for P89V51RD2 ISP programmer circuit

Hi,

 

Its preferrable to go for available programmer as to make own programmer, we need another controller and again we have to program it.

 

P89V51RD2 has inbuilt ISP Bootloader and its very easy to program it. If you want, I can give my own designed kit.

may I see your desagn?
