P506 - Quad CAN Bus Interface PMC

The P506 is a 32-bit/33MHz PMC with four CAN interfaces. They support CAN Protocol Version 2.0A/B, standard and extended data frames, remote frames, 0..8 bytes data length and a programmable data rate of up to 1 Mbit/s.

The P506 is based on the USM concept. USM Universal Submodules make PMC modules more flexible than ever. The CAN bus interfaces are realized via four IP cores implemented inside its onboard FPGA. This function can be changed at any time through implementation of different IP cores. The corresponding line drivers are realized on the USM which is simply plugged on the P506.

The I/O mezzanine module is suitable for any PMC compliant host carrier board in any type of bus system, i.e. CPCI, VME or on any type of stand-alone SBC in telecommunication, industrial, medical, transportation or aerospace applications. It offers long-term availability for at least 10 years and is qualified for operation in the extended temperature range.
