8051 on-chip debugging

25/03/2011 - 10:56 von Schueler | Report spam
Folks,



I would like to use the 8051 derivate MAXIM DS89C4xx in one of my
experiments regaring motor controlling but I am worried about the on-chip
debugging capabilites. I could not find any material on this topic. Does
anybody know whether the DS89C4xx series support debugging or not? Any other
known 8051 derivate which features on-chip debugging and which offers an
evaluation board?



Thanks in advance.

Regards B. Schueler

This is because most MCU don't have on chip debugging capabilities.
Over the last 5 -10 years JTAG has become more common. The 8051 family
which is much older does not have it on the majority of parts.

What sort of on chip debugging are you looking for? The Atmel and NXP
parts have on chip debug capability when used with an Ice (they use the
Hooks and Enhanced Hooks system that does nto require a bondout part)

Others such as Sylabs do have JTAG.

Had you asked last month I had two 8061 ICE to give away (a Nohau and a
Hitex) but they have gone now. Might be worth a punt on ebay for
Emulators as both iSystem and Signum did Ice for the Dallas/Maxim part
you are interested in.
