Hello fellow freaks!

I’m starting a new project that will incorporate a CAN transceiver. Never used CAN before so looking to you fellows for recommendations.

Currently the only specification I have of the object to interface with is CAN 2.0B passive up to 500k.
Can any of you freaks recommend a good CAN transceiver?

Thank you!

What CAN controller are you going to use?

I hope the OP knows the difference between a transceiver and a controller; hence my question :)

This #*&%^ forum absolutely refused to let me make a simple edit in my last post, but it finally let me edit it down to one word. I am getting really sick and tired of dealing with this $&(#^$&*!!!!

Point well taken. The OP might be talking about the actual CAN chip????

As for the transceiver interface chip, it also depends on the environment and type of service its going to be used in. Some designs might require a specific ISO standard. Some interface chips withstand very high voltages, some are designed to operate single ended if one of the differential wires fails, etc. All the major manufactures make these types of chips.

Here is a link to an ATMEL CAN interface chip data sheet:

You will need the data sheet for whatever interface chip you choose from whatever manufacturer.

If you want to use an ATMEL AVR CAN processor chip, the AT90CAN128 family is the easiest one to obtain. The automotive ATmega64M1 and ATmega64C1 families are typically harder to get like most specialty automotive products.

If using one of the CAN AVRs is not possible, the Microchop MCP2515 could be a nice solution (but you still need a transceiver).

The original industry standard was the PCA82C250, but EMC rules are messing that up now.
You'll do fine with the TJA1050 from NXP. They're selling millions of them to the automotive industry.

I have used the AT90CAN series and they are really work perfect.

As a remark, I would like to say that it took for me enough time to understand it in deep and to make it function for my needs.
