I am using NXP P89LPC954 microcontroller( www.kynix.com/.../P89LPC954FA,529.html ).
I am having problem with In System programming(ISP). When i solder it

Here&amp;#39;s a pro tip, use a SOCKET, and diff the content of the
micro-controller in the universal programmer vs the ISP. Know the
checksum of your image, and validate it.&lt;/p&gt;

&lt;p&gt;
You can typically buy parts preprogrammed from a distributor, they
usually charge a fee to do the work.&lt;/p&gt;

&lt;p&gt;
There are definitely a whole class of old devices that I&amp;#39;d program
before populating on a board, as the wiring on the board can
interfere with the programming in system.&lt;/p&gt;

&lt;p&gt;
Tester time is expensive when building/testing thousands of
device, wasting time programming and erasing will add to part costs,
most people want the parts in the least expensive form available.
When building multiple parts/boards, your stockroom wants a single
SKU&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
