Did you mean 89S5x instead of 89C5x, Mr Premkumar9?
was the earlier programmer looks like ISP or parallel programmer?
i just saw the cross post
your programmer is LOGIC POWER Flash Mcu Serial Port Programmer Model: SPP 1.03
Because, 89C52 can't be programmed by ISP methods!!
why not put a schematic or make and model of your programmer.
better use 89S52 series. it would not need 12V . For changing the program bits like clock etc, you definitely need a High voltage parallel programmer.
