Hi, We're trying to understand some slight differences in timing behaviour we are getting when running CAN-based networks for Infineon C515C, Infineon C167 and Philips LPC2129. I believe the C515C and C167 use 82527 cores, and the LPCs are based on SJA1000. Anyone able to confirm this? Thanks, Michael.

I have used the Infineon C164. It's CAN controller is register compatible with the Intel 82527 CAN controller. I'm not sure what you mean by "82527 cores". I think it is just register compatible. Joe

Michael, you are correct that the listed Infineon devices have the Bosch FullCAN which is compatible to the Intel 82527. This is a FullCAN implementation with the option to use one message object as a "garage door" opening the CAN controller for all messages on the bus. Besides that the limit is basically 16 message objects. The improved version of this module is the "TwinCAN" The LPC2000 device have a new CAN controller that was derived from the SJA1000 but has superior filtering and buffering. Unfortunately the FullCAN mode of the LPC2000 is not functional but in Basci CAN mode filtering is very extensive. If less or equal to 16 messages are sufficient, a FullCAN imlementation has benefits in regards to the CPU load. If more messages or more flexible filtering for groups of messages is needed, the LPC2000 implementation has more features to offer.
