Hi, This is Harish Chincholi, going to work on CAN protocols, I am looking for 3 CAN Module Microcontroller, I have found TMS470R1B768 Microcontroller with 3 CAN Module. I want to know if there is Evaluation kit available which supports this Microntroller. If there is any other Microcontroller which has 3 CAN Modules with evaluation kit, suggestions would be helpful.
Thanks & Regards, Harish Chincholi

But why do you need three CANs?
I need to send messages to 2 PC's continously.. that is having one dedicated transmitter(PC1) which is continously sending messages to remaning 2 PC's.. To all the PC's I like to have evaluation boards interfaced so as to recieve CAN message.
still, are you sure you cannot solve this with 2 CAN networks? I don't see immediately why not, to be honest. Under certain conditions, even a single CAN controller will do.
This definitely sounds like a mistake, unless you are worried about the latencies with more than one transmitter on the cable.
CAN is a bus protocol, so you do not need a large number of individual point-to-point connections unless you need very high tranfer rates.
But in such case: if your microcontroller is not capable of running the bus at a higher baudrate, then it will probably not be fast enough to run multiple point-to-point links at max speed either.
may be there are three seperate CAN busses ;)
whats about NXPs MCUs for example the LPC2294 ?
provides a maximum of 4 CAN interfaces.
for example the olimex Evalboard elmicro.com/.../lpc-e22xx.pdf has 4 CAN connectors mounted.
Yes, vehicles often uses two. But three?
And in this case, the description doesn't sound like three busses because of latency or different baudrate but more because the OP wants several P2P connections.
the amount of busses is not point of request.
I'm working on systems with a lot more CAN busses at one time in a CAN bus network.
May be there're more than one vehicle connected ;)
It is not clear from the request whether it's significant or not - hence the question.
As ever, knowing the reason for the request would enable people to give informed suggestions: it may or may not be sensible to use 3 interfaces in this particular application - but, without any details of the application, it is impossible to tell.
However, it is not unreasonable to speculate that, if there really were a good reason for it, the OP might have taken care to mention that...
