Hello Friends,
I had tried programming p89v51rd2 IC with flashmagic . I burnt the same code in 5 same IC's but only 1 IC gave the output and the other 4 IC's aren't giving any o/p.
How can I check whether the IC's are working or not?Is there any way to troubleshoot the IC's coz the IC's are too costly..Pls Help...

A programmer will normally run several checks on a device before erasing and programming. If the programmer is happy with it, then in my experience that is usually good enough. There are more than enough reasons for things not to work besides bad parts, which in a career spanning half a century has happened maybe twice.
