Can the TNT4882 be used as a controller?

[philip]

If so,how do I get a hardware reference manual
with bus timing and electrical characteristics?

Hi,

The TNT4882 does not have controller capabilities. This chip is only for talker/listener applications.

You can get all the information on the available chips at :

Hope this helps!
