Hi, thank you for your kind attention. Lucky someone here knows well 
STCs..

I've a club light "LED bar" driven by DMX line, inside there is an STC 
12c5616ad and repairing the lamp I broken it. There is no service for 
this lamp available so I would like to clone one STC reading the 
firmware from an equal lamp (I have). Is that possible?

I downloaded the datasheet but they don't talk about firmware 
protection, neither how to dump it, if you never deal with such feature, 
do you know someone who has experience how to proceed?

I've another question, it looks programming these chips need only an 
RS232 port on a PC and some components to interface the RS232 line 
levels (to TTL), I got it right? Then it looks very simple to 
program/read it.

Thank you a lot for your kind support

Datasheet... Page 7. / 1.1 Features: "-Code protection for flash memory 
access"

Thank you for answering,
I got from experts the right answer, the STC bootloader natively doesn't 
support the read feature, so it's impossible to dump anythig and that 
means it's the best protection ever, and always.
THere is nothing to do here.
